The Department of Intellectual Property announced on March 4, 2024, that “Koh Yao Sea Cucumber” has been registered as the fourth geographical indication (GI) product of Phang Nga Province. This recognition was granted due to the product’s unique characteristics and its wide range of potential applications, including both food consumption and use in the production of medicines and food supplements.

Koh Yao Sea Cucumber has distinctive characteristics that significantly differ from ordinary sea cucumbers. Sea cucumbers that generally live in the sea are often stressed, which affects their physical growth. In contrast, Koh Yao sea cucumbers are raised in mud and sand ponds with channels that allow seawater to flow in and out. The breeding area is limited to Koh Yao District, in Phang Nga Province, which has a rich biodiversity and is suitable for the habitation and breeding of aquatic animals. Koh Yao sea cucumbers are raised together with other marine species, which contributes to making them larger, firmer, and thicker than sea cucumbers raised elsewhere. Sea cucumbers indeed feed on the sediment in the pond and the waste from other organisms, and they tend to live at the bottom of the pond and do not move much. These differences make Koh Yao sea cucumbers a sought-after product in many countries.

They now join the respectable list of GI registered for fresh fish, mollusks, and crustaceans in Thailand, which also includes the Suratthani oyster, Pla Rad (giant gourami) from Lumnam Sakae Krang Uthai Thani, Pla Chon (snake-head fish) from Mae La, the Songkhla Lake seabass, the Surat Thani stinging catfish, the Mae Klong mackerel and the Bang Phae giant freshwater prawn.

Within this past year, Thai elephant pants, a product that has been produced and sold in Thailand for a long time, have become increasingly popular among both Thais and foreigners. This has led to a call from the public to promote elephant pants as part of Thailand’s soft power.

In a bid to respond to this call, the Thai government has conducted a market survey of all elephant pants produced and sold in Thailand. The results outlined that elephant pants sold in Thailand are both domestically and foreign-produced. In response, the Department of Intellectual Property has initiated measures to inspect and raise awareness among manufacturers and distributors regarding their intellectual property rights, in particular the copyright attached to Thai elephant patterns, which belong to Thai creators. Additionally, a collaboration with the Customs Department has been established to scrutinize imported goods that may potentially infringe on said intellectual property rights.

Moreover, there are currently other patterned pants created by Thai designers to showcase the identity of different provinces and localities in Thailand, such as the cat-patterned pants from Korat Province and the Mae Klong River Mackerel-patterned pants from Samut Songkhram Province.

The Department of Intellectual Property has informed and assured manufacturers and creators that if the patterns of these pants are designed without copying the work of others, they will be protected immediately upon creation. However, as for other types of artworks, it is still recommended to file a copyright notification with the Department of Intellectual Property to use as evidence of copyright ownership.

The Thai Department of Intellectual Property (DIP) introduced a “Target Patent Fast-Track Program” in 2022. It is tailored for patent and petty patent applications associated with creative inventions in the fields of medical sciences, public health and, since the 1st of January 2024, future food.

This program is designed to accelerate the examination process, aiming to be completed within 12 months for patents and 6 months for petty patents from the date the applications are accepted in the program. It has the comprehensive goal of addressing the ongoing public health crisis and aligning with the global emphasis on the importance of consuming healthy and sustainable food.

Conditions for participation in the program

Inventions eligible for participation must comply with the following formal and substantive requirements:

Formal requirements:

  1. It must have been filed as a patent application for which substantive examination has been requested or as a petty patent application which has been pending for more than three months.
  2. It must have been filed with the Thai DIP as a first office (without claiming the priority of a foreign application) or as a PCT application with the World Intellectual Property Organization (WIPO) through the Thai Patent Office (PCT Receiving Office: RO/TH).
  3. The application must not have more than 10 claims.
  4. The application must be available on the DIP e-Filing system.

Substantive requirements:

  1. It must relate to:
  • Medical sciences and public health: Technology associated with medical science and public health, encompassing products, processes, materials, equipment, or medical tools intended for public benefit.
  • Future food:

              (1) Novel food: This category relates to the production of food using new processes, where components  may be employed in a new form or through the application of innovative technology in the production, storage, or preservation of food.

              (2) Health supplements: This category includes food designed to offer essential nutritional value, providing benefits in enhancing the body’s immune system, supporting various bodily systems, and delaying the deterioration of various organs.

              (3) Organic food: This category includes organic farming, which prohibits chemical food additives, hormones, and antibiotics. Genetically Modified Organisms (GMOs) are excluded from this category.

              (4) Medical food: This category covers products used as substitutes for medicines or nutritional supplements under the supervision of a doctor.

  1. The invention must have the potential for commercial use, and the applicant must have plans for production and distribution, or a license agreement for the invention must be prepared.

Procedure to participate in the program

A request must be filed by the applicant, along with an explanation detailing how their invention meets the conditions for participation in the program, supported by evidence such as a utilization plan.

The request should be filed through e-Filing between the 1st and 10th of each month. Participation in the program is free of charge.

The list of the applications selected is announced on the DIP official website by the 5th of the following month.

 

Examination process under the program

Throughout the examination process, any office actions will be communicated via the e-filing system. Upon receipt of the office action, the applicant must respond within 30 days. To facilitate the timely filing of the amendment, a video conference will be arranged with the examiner to elucidate the details of the office action, ensuring precise and effective amendments.

Failure to meet the 30-day deadline will result in the applicants being deemed to waive their participation rights in the program, leading to the examination procedure being converted back to the standard examination route.

On January 3, 2023, less than one year after committing to a shorter examination timeline for trademark applications with a short list of goods and services, the Department of Intellectual Property set up a new accelerated examination process for trademark applications. The timeline from filing to issuance of the certificate of registration will be of only 4 months, which is a third of the average time it takes under the standard procedure.

Unlike the fast-track examination that was announced last year, applicants who would like to use this mechanism have to specifically request it. No additional official fee will be charged, but their application will have to meet the following cumulative requirements:

(1) The application must be submitted via the DIP e-filing system;

(2) The application must be a single-class application with no more than 10 items;

(3) The applicants should submit together with their application the search results for identical or similar prior marks (screenshots of the prior marks found on the DIP database may suffice);

(4) The applicants must provide a document, in Thai language, outlining the reasons why the examination of their trademark applications should be expedited (for example: a marketing plan or intended use of the trademark).

This latest fast-track procedure is however not applicable to trademark applications submitted through the Madrid Protocol, the examination of which is currently still significantly slower than applications filed via the domestic route.

The Thai Department of Intellectual Property (DIP) introduced a new guideline for issuing electronic certificates, known as e-certificates, in parallel with physical certificates. This initiative, effective from April 19, 2021, aims to modernize certificate issuance, maintenance, and verification processes. The guideline includes a new verification system accessible on the DIP website, utilizing QR code and reference numbers to enhance efficiency and accessibility. Importantly, these e-certificates, supported by the Electronic Transactions Act B.E. 2544 (2001), hold equivalent legal standing to their physical counterparts. This significant legislation ensures that electronic documents and signatures are afforded identical legal weight and implications as traditional paper certificates and signatures.

Benefits of e-certificates

Previously, obtaining certificates for patents, petty patents, or designs implied a convoluted process of paperwork and manual verification. The reliance on physical certificates also posed inherent risks such as loss, damage, or forgery, compromising the integrity of the certification process. Additionally, the traditional approach incurred significant logistical overheads associated with storage and international transmission of paper documents.

The notable advantages of these new certificates are as follows:

Process of obtaining and verifying e-certificates

Anyone can access an e-certificate via the DIP database or by scanning the QR code on the physical certificate. The digital certificate contains all necessary information found in the physical certificate. It also includes filed specifications, claims, abstracts, and drawings (if any) for patents and petty patents, as well as claim, brief description (if any), and drawings for designs.

Here is the reference link for the complete example of an e-certificate: https://patentservice.ipthailand.go.th/ecert/qr/256401000050717

Verification of e-certificates can be done through the DIP-managed system accessible at https://verify.ipthailand.go.th/. Users can input the reference number located below the QR code on the certificate to confirm its validity.

In Thailand, a trademark renewal request can be filed within 3 months prior to the expiration date of a trademark. Late renewal is possible in the 6 months following the expiration date (grace period) and sanctioned with a 20% surcharge of the official fees due.

 

Ordinarily, the recordal of the trademark renewal and the issuance of the new certificate of registration will take between 3 to 4 months from the filing date of the renewal request.

 

In March 2021, the Thai Department of Intellectual Property (DIP) introduced a new fast-track system cutting down this waiting period to one hour. To benefit from this scheme, trademark owners or their representatives must file the renewal request in person at the DIP and specify that they wish to have their request dealt with under the fast-track system. They may then retrieve the new Certificate of Registration within one hour of having filed the request.

 

While this system can also be applied to late renewal requests, it is limited to trademarks that do not cover more than 30 items. Similarly, if any amendment other than deleting items from the list of goods and services is required (such as change of agent, change of owner’s name/address), the renewal request will be processed following the usual timeline.

On April 16, 2021, the Department of Intellectual Property announced a new expedited examination process for trademark applications. Under this fast-track scheme, a trademark will be examined within as few as 6 months from the Thai filing date – instead of the standard 10 to 16 months.

 

This fast-track system is automatically and only applied to applications (filed in person, online or via mail letters) where no more than 10 goods or services are listed, and if all items are included in the traditional list of goods and services used by the Thai Trademark Office. A bilingual list (Thai-English) has recently been made available to the public.

 

If the application is submitted together with evidence of use, or amended or assigned during these 6 months, it will be processed following the traditional timeline.

The Thai Department of Intellectual Property has just announced that the deadlines to submit additional documents or respond to office actions for patent, design and petty patent applications filed in Thailand, if falling between the 16th of April and the 31st of May 2021, are automatically extended to the 30th of June 2021.

This extension is not applicable to PCT national phase applications.

Our Insights

As the substantive examination tends to be lengthy in Thailand, although reforms are underway to shorten the process, ASEAN and Japanese patent holders may request that the examination be expedited under one of the two operational fast-track systems. It may shorten the process by up to 3 years.

These fast-track paths are also called “Patent Prosecution Highway” (PPH), referring to a program that allows patent applicants to request accelerated substantive examination of their patent applications by utilizing a positive examination outcome from other patent offices. These PPH programs are subject to bilateral or regional agreements between countries. They can be used with a number of patent offices worldwide, for instance with the United States Patent and Trademark Office (USPTO), the Intellectual Property Office of Singapore (SG) and the Japanese Patent Office (JPO), as well as with patent offices across Europe and several in the ASEAN region.

PPH pilot program with Japan

The Thai Department of Intellectual Property (DIP) and the JPO are cooperating since 2014 to accelerate the substantive examination of patents based on prior applications filed in Japan or Thailand. This pilot program is currently in force until December 2025, and will probably be extended further by additional 2-year periods.

This procedure is available for (i) applications claiming priority from a JPO application, (ii) national phase PCT applications based on a JPO application, (iii) national phase PCT applications without priority claim or with priority claim of a prior PCT application without priority claim, where the PCT national phase has also been filed in Japan. Once the application or some of its claims is/are declared patentable by the JPO, the applicant may ask that the corresponding patent application pending before the DIP be examined under the PPH program. It is possible to request for the PPH program either through e-filing or in person when requesting substantive examination or at a later time, but before any office action is issued by the DIP during the substantive examination=.

Several documents are required:

  1. The PPH request form.
  2. Copies of all office actions issued during substantive examination by the JPO, along with their translations in either English or Thai.
  3. Copies of all claims declared patentable by the JPO, along with their translations in either English or Thai.
  4. Copies of references cited by the JPO examiner; the translation of the references is not required.
  5. A table connecting the claims of the JPO application with the application submitted to the DIP.

After receiving the request, it will take approximately 6-10 months from the date on which the request is filed to receive the first office action, which may either require the applicant to file an amendment or to proceed with the payment of the grant fee. In general, Thai examiners tend to align their assessment with the examination results of the JPO; they would only carry out an additional examination to ensure that the patent application meets the specific requirements set out by the Thai Patent Act and corresponding regulations. No official fee is charged for participation in the PPH pilot program.

ASEAN Patent Examination Co-Operation (“ASPEC”)

ASPEC is a patent work-sharing program implemented by the IP offices of 9 countries in ASEAN: Brunei, Cambodia, Indonesia, Lao PDR, Malaysia, the Philippines, Singapore, Thailand and Vietnam. It is operational in Thailand since 2013. It promotes the use of search and examination reports or PCT reports issued by another participating IP office to speed up the examination by the IP office designated subsequently. It is free of charge for the applicant. The ASPEC request can be filed together with the substantive examination request, at the designated IP office or through the ASEAN IP portal. In Thailand, it is possible to file an ASPEC request through either e-filing or in person, before any office actions is issued by the DIP during the substantive examination of the application. All relevant documents must be provided in English.

The required documents are as follows:

  1. The duly filled ASPEC request form.
  2. A copy of the prior search report.
  3. A copy of the examination results.
  4. A copy of the patent certificate (if any).
  5. ASPEC claims correspondence table.

As of July 2023, 320 ASPEC requests have been filed in Thailand, mainly by holders of a patent application in Singapore (76%). The average time from the filing of the ASPEC request to the first office action in the 6 ASEAN States where it has been used is 9.3 months.

In Thailand, the scope of invention protection falls under the governance of the Thai Patent Act B.E. 2522, which encompasses both patents and petty patents. These classifications are contingent upon the complexity of the invention and the number of claims for protection. However, these patent types also vary in terms of the examination process and the duration of their protection period. Consequently, applicants may consider converting their applications type during formal examination stage between patents and petty patents, as stipulated in section 65 quarter:

The applicant for a petty patent or the applicant for an invention patent may request to convert his application for a petty patent to an application for an invention patent or an application for an invention patent to an application for a petty patent before the registration of the invention and the grant of the petty patent or before the publication of the application under Section 28, as the case may be. The applicant may claim the date of filing of the original application to be the filing date of the converted application in accordance with the rules and procedures prescribed in the Ministerial Regulations.”

Factors to consider

  • Cost considerations: Petty patents typically entail lower application fees and maintenance costs compared to patents. This can significantly reduce the financial burden for applicants seeking protection for their innovations, especially in cases where cost management is a priority.
  • Scope and duration of protection: The choice between a patent and a petty patent determines the level of protection for the invention. Patents provide broader coverage, allowing for a wider range of claims and stronger enforceability. Conversely, petty patents offer narrower protection, with claims restricted, typically not exceeding 10. Moreover, patents offer longer protection compared to petty patents. If an applicant initially opts for a petty patent but later realizes the greater potential value of their invention, they can convert their application to a patent to ensure comprehensive protection and exclusive rights.
  • Examination period: Petty patents offer a shorter processing period due to simplified requirements and the absence of substantive examination. This process can be advantageous for applicants aiming to secure intellectual property rights swiftly, particularly in fast-paced industries or competitive markets, enabling quicker access to legal protection for their inventions.

Filing a conversion request

The request must be submitted along with the necessary documents before the patent application is published under section 28 or before the petty patent is granted. Within the request, the applicant must specify whether to retain the original filing date or amend it to match the conversion request date. An official fee of 100 baht is associated with this process.

After the DIP officer receives and acknowledges the request, a new application number will be generated to align with the newly designated patent type, which typically takes a few months to process.

Required documents

  • Conversion request form (SorPor/OrSorPor/004-Kor)
  • Supporting documents such as the Statement of Applicant Right (SAR) or Deed of Assignment (DOA). Previously submitted copies of these documents, affixed with a certified copy stamp, may be reused.
  • Application form along with specification, claims, abstract and drawings (if any). In case of conversion from patent to petty patent, if the number of original claims filed was more than 10, it must be reduced to not exceed 10 claims for petty patent.

Country code top-level domain (ccTLD) names are used to identify the country where a domain name was created. Generally, each country is attributed a 2-letter country code, which is “.th” for Thailand.

Types of third-level country code top-level domain names in Thailand

The registration of ccTLD names in Thailand is the responsibility of the Thai Network Information Center Foundation (THNiC).[1]

There are seven categories of third-level ccTLD names that can be registered in Thailand:

  1. .ac.th: for academic institutions;
  2. .go.th: for government entities;
  3. .mi.th: for the Royal Thai Armed Force agencies;
  4. .net.th: for telecommunication business license licensees;
  5. .or.th: for non-government organizations and nonprofit organizations;
  6. .co.th: for (a) juristic entities registered in Thailand or abroad; or (b) owners of trademark registered in Thailand or abroad; or (c) persons or entities registered for VAT in Thailand; or (d) State Enterprises;
  7. .in.th: for all types of entities with an official location in Thailand, Thai individuals or foreigners with a Thai work permit.

Each of these seven types of domains follows its own registration rules, prescribed by the 2020 Domain Name Registration Policy[2] and the Third-Level Domain Name Registration Guidelines.[3] While the 4 first categories are the most restricted, the last 3 are of more interest for foreign companies and individuals.

Rules for “.co.th” domain naming in Thailand

Generic rules to follow for domain naming are the ones that apply most commonly. The name must be made of roman letters or numerals, have between 1 and 63 characters and can use an hyphen (-).

In addition, “.co.th” can only be granted for:

– The full name of a company (registered in Thailand or overseas), a portion of the company name or an abbreviation of the company name – the normal order of the words should be followed if the company name is made of more than one word.

– The name of a Thai registered trademark. In this case, the domain name will be registered in the name of the owner of the trademark.

– The name of a foreign registered trademark.

If the domain name is based on a foreign registered trademark or a foreign company name, an agent with a registered address in Thailand will be designated as “agent on record” for the owner of the domain name.

Procedure for obtaining a “.co.th” domain name in Thailand

All applicants must have a verified account with the THNiC to receive approval and have a contact person with a registered address in Thailand.

In addition, if the application is filed by an agent based in Thailand, the following documents are required:

– If the name used is the company name:

1. The company certificate of the applicant (with an English translation if issued overseas),

2. A Power of Attorney (simply signed), and

3. An authorization letter from the applicant to use the company name as the domain name in Thailand.

– If the name used is a Thai registered trademark:

1. The trademark registration certificate,

2. A Power of Attorney (simply signed), and

3. An authorization letter from the applicant to use the Thai trademark as the domain name.

– If the name used is a foreign registered trademark:

1. The trademark registration certificate with an English translation;

2. A Power of Attorney (simply signed);

3. An authorization letter from the applicant to use the foreign trademark as the domain name.

The request should be considered by the registrar within one day. If approved, the applicant will have to pay the registration fee.

Transfer of a “.co.th” domain name to a new holder in Thailand

Transfers of these domain names to a new holder can be granted in particular in the following cases:

– When the trademark used for the domain name has been assigned to another entity/person;

– Following a change of legal entity (e.g. M&A);

– When the foreign owner of the domain name who appointed a Thai agent to hold the domain name on their behalf registered a Thai trademark or registered a company in Thailand; in this case, the Thai agent can but is no longer required to hold the domain name.

In this last scenario, the documents required for the transfer of domain name from the agent to the actual owner would be as follows:

– If the foreign owner registered a trademark in Thailand:

1. A copy of the Thai trademark registration certificate, and

2. A copy of the foreign company registration certificate.

– If the foreign owner registered a company in Thailand:

1. A signed copy of the Thai company registration certificate issued within the past 6 months, and

2. A signed copy of the Thai tax registration certificate.

Renewal of a “.co.th” domain name in Thailand

A third-level domain name can be registered and renewed for a minimum of one year and a maximum of ten years. If it is not renewed before the expiry date, three successive grace periods of a total of 60 days will apply:

  • A 5-day grace period during which the domain name is auto-renewed.
  • A 24-day hold period during which the domain name is unavailable.
  • A 30-day redemption grace period after the command to delete the domain name has been sent to the operator; the renewal of the domain name during this period will require the payment of an additional redemption fee of 1,600 Thai Baht.

SLD.th available since 2021

 “.th” is available as a secondary level ccTLD since 2021.[4] Three rounds of applications are open per year.[5] Owners of SLD.th domain names can be Thai citizens, companies incorporated in Thailand or owners of a Thai registered trademark.

However, it is at significantly higher cost than third-level domain names as the official fee is of THB110,000 (around USD3,300).

Third party observations (TPOs) are an alternative approach to formal oppositions to patent applications that allows third parties to file relevant documents or evidence with the Patent Office while remaining anonymous. Similarly to oppositions, the aim of submitting a third party observation is to challenge the patentability of an invention. Third parties should thus provide evidence that could be considered by the patent examiner when assessing whether the invention meets the patentability criteria, e.g. evidence relating to prior art, novelty, inventiveness and industrial applicability.

TPOs overseas: a formal procedure

Both the European Patent Office (EPO) and the US Patent and Trademark Office (USPTO) have specific legal provisions pertaining to TPOs.

In the EPO, any person may file an observation after the publication of a European patent application. Once the observation has been filed, it will be communicated to the applicant who will be allowed to respond. In the meantime, TPOs will be considered by the examiner during the substantive examination the application if they are substantiated. They might be referred to in the first office action issued after they have been filed.[1]

The USPTO refers to “TPOs” as “third party preissuance submissions” whereby third parties can submit documents that may be relevant to the examination of a new application, such as granted patents or published patent applications. Such submissions must be filed within 6 months of the first publication date of the application by the USPTO and before any office action on the merits or notice of allowance is issued.[2]

TPOs before the Thai Patent Office: an informal pre-grant opposition mechanism

Formal oppositions are regulated by Section 31 of the Thai Patent Act and can be filed within 90 days from the publication date of a patent application, by any person who considers that the invention does not meet the requirements set forth in the Thai Patent Act. During the opposition process, the burden of proof will lie on the opposing party. The applicant will have to file a counterstatement to the opposition, failing which their patent application will be deemed abandoned.

On the other hand, TPOs are not mentioned in the Thai Patent Act. However, they are allowed in practice by the Thai Patent Office. Under this current informal practice, any third party can anonymously file evidence concerning the novelty, inventiveness, and industrial applicability of a pending patent application at any time before it is granted. Since this is an informal mechanism, there is no specific form to fill in and file with the evidence, nor official fee to be paid. Likewise, the patent examiner will be under no obligation to consider the observations during the substantive examination of the application.

Therefore, the main advantages of TPOs in comparison to oppositions are that they can be filed (1) anonymously, which may circumvent conflicts with business partners, and (2) at any time during the examination process, before and after the publication of the application. However, since they do not follow any formal procedure, they may simply be dismissed at the discretion of the patent examiner

Foreseen changes to the TPOs procedure in Thailand

TPOs will be officially recognized in the upcoming new Patent Act.[3] Under the draft provisions, patent applications will undergo two rounds of publication. The first publication of the application will occur after the end of an 18-month period from the date of filing in Thailand or the first priority date, and the second publication once the substantive examination has been completed. Third party observations can be filed after the first publication of the application and before the second publication.

There is no provision regarding the acknowledgement of TPOs under the draft new Patent Act, nor any provision stating that they should be forwarded to the applicant or that the patent examiner is obliged to take them into consideration during the examination process. It could be assumed that formal guidelines will be drafted on this matter once the new Patent Act is adopted.

An international concept

The origin of geographical indications can be traced back to the 1883 Paris Convention for the Protection of Industrial Property, under the designation of “indications of source” or “appellations of origin”, in an effort to protect as IP assets agricultural and artisanal products that form the traditional, cultural and culinary landscape of countries. Other agreements were made to keep in check the right use of indications of source and appellations of origin (the Madrid Agreement for the Repression of False or Deceptive Indications of Source on Goods in 1891 and the Lisbon Agreement for the Protection of Appellations of Origin and their International Registration in 1958), to which Thailand is not signatory.

The TRIPS Agreement covers rather effectively the matter in its Section 3 on Geographical Indications, defining them as “indications which identify a good as originating in the territory of a Member, or a region or locality in that territory, where a given quality, reputation or other characteristic of the good is essentially attributable to its geographical origin” (Article 22). It also imposes on member States an obligation to provide legal means to prevent misuse of geographical indications, including misuse through trademark registration. Geographical indications for wines and spirits benefit from a specific protection (Article 23).

To approach this somewhat vague concept more clearly, here are a few examples of GIs recognized around the world: Gruyère and Gorgonzola cheeses, Basmati rice, Darjeeling tea, Australian wild abalone, Zhostovo paintings…

How to protect a geographical indication in Thailand?

Geographical indications can be protected by different means. In most countries, like Thailand, a registration system has been set up, allowing for official and formal recognition of geographical indications at the national level. However, the geographical indications can also be protected through the use of certification or collective marks, administrative certification procedures or unfair competition regulations, or a combination of some or all of these methods.

Thailand’s geographical indications’ registration system stems from the 2003 Geographical Indications Protection Act. Its Section 3 gives a definition that overlaps with the definition given by the TRIPS Agreement.[1] The Act also excludes the registration of two types of geographical indications: generic names and indications conflicting with public order, good moral or public policy.[2]

Registration process

Thailand’s geographical indications’ registration system is in place since 2004 and open to foreign geographical indications that are or can be protected in their country of origin.[3]

Three types of persons or entities can apply for registration:[4]

  • Government agencies or public companies and entities having a mandate covering geographical origin of goods;
  • A person or a juristic person involved in the trade of goods for which a geographical indication is used and having its place of residence/registration where the geographical indication originates;
  • A group of consumers using the goods belonging to a geographical indication.

The application must include details relating to the quality and reputation of the goods and the geographical indication.

The application will be processed within four months of the filing date. If it does not comply with the requirements set forth in the Act, the applicant will be notified and will have 90 days to appeal the decision before the Geographical Indications Board.

If it complies with the requirements, the application will be published and any interested party may object to its registration within 90 days from its publication date. If no opposition is filed, the geographical indication will be registered as from the filing date of the application.[5] If an opposition is filed, the counterstatement should be filed within 90 days, failing which the application will be deemed abandoned.

The applicant and the opponent have the right to appeal against the registrar’s decision before the Board of Geographical Indications.

Chapter III of the Act focuses on correction and revocation of registered geographical indications. It is to be noted that geographical indications that become generic overtime can be revoked upon request.[6]

A ministerial regulation clarifies the requirements for the registration of a geographical indication.[7] Foreign applicants must be represented by an authorized person in Thailand through a legalized Power of Attorney. All supporting documents must be translated in Thai (certified translation).

The application must contain the following information: details about the applicant; representation of the geographical indication (name or symbol); description of the goods and their characteristics; information on the connection between the goods and the geographical origin; location of the geographical origin; examples of use of the geographical indication on the goods; and a photograph of the goods.

Misuse of geographical indications & sanctions

If the geographical indication is misused by the producer of the goods for which it has been registered, i.e., not used as per the conditions set forth in the registration and application documents, the registrar may order this person to stop using the indication for up to two years.[8]

Once the geographical indication is registered, other acts that amount to misuse are prohibited by law:

  • Use of a geographical indication in a way that misleads others to falsely believe that the goods sold are from the geographical origin that has been registered;
  • Use of a geographical indication in a way that causes the public to be confused or misled as to the origin of the goods and to their quality, reputation or other characteristics, with the intention to cause damage to competitors.[9]

These acts are sanctioned by a fine of 200,000 Thai Baht.[10]

In addition, Thai’s geographical indications are also protected indirectly under the following laws:

  • Thailand Criminal Code 1956: under Section 271, a person selling goods using inaccurate geographical indications in order to deceive the buyer as to their origin or quality will be sanctioned by three-year imprisonment or a fine of 60,000 Thai Baht, or both.
  • Consumer Protection Act 1979: Sections 22 and 47 sanction the use of deceptive advertisements to sell goods, including as to their origin, by six months imprisonment or a fine of 50,000 Thai Baht, or both.

Registered geographical indications in Thailand

At the time of writing this article, a total of 174 geographical indications have been registered with the Thai Department of Intellectual Property: 18 from abroad and 156 for Thai products.

As can be seen in the above chart, in the past decade, the Thai government has scaled up its efforts to protect the value and specificity of Thai products by trying to register at least one geographical indication per Thai province. A few examples of Thai GIs are Phetchabun sweet tamarind, Doi Tung coffee, Chaiya salted eggs, rose apples from Petchaburi, Koh Kret pottery, Koh Phangan coconuts, Khao Yai wine and Sisaket garlic. Thailand’s government also registered a few geographical indications overseas.

Meanwhile, the number of foreign geographical indications remains low. The current foreign geographical indications registered in Thailand, listed by registration dates, are: pisco from Peru (2005), champagne from France (2006), Brunello di Montalcino from Italy and cognac from France (2007), prosciutto di Parma from Italy and scotch whisky from Scotland (2009), Napa Valley from the United States (2011), tequila from Mexico (2012), Barbaresco and Barolo from Italy (2013), Buon Ma Thuot coffee from Vietnam (2014), Parmigiano-Reggiano from Italy (2016), Kampot pepper and Kampong Speu palm sugar from Cambodia and Shan Tuyet Moc Chau tea and Van Yen cinnamon from Vietnam (2017), Grana Padano from Italy (2019) and the most recent, Higashine cherry from Japan, registered in 2021.

A complete updated list is available on the DIP website at the following link:

http://www.ipthailand.go.th/th/gi-015.html

Producers or traders of the goods that benefit from a registered Thai geographical indication can apply for the right to use the geographical indication’s logo or symbol at the DIP. They must provide documents summarizing the production process of the goods. If their application is approved by the Board of Geographical Indications, they will obtain a license to use the logo or symbol for a period of two years.

Trade secrets in Thailand are still today the somewhat neglected stepchild of IP rights. With patents, trademarks and copyright being the favored siblings, trade secrets are too often overlooked among all IP assets that it would be in a company’s best interest to protect. While protecting a trade secret is not as straightforward as registering a trademark or a patent, it might indeed be worthwhile for companies to take all appropriate steps to identify their assets that qualify as such and to set up minimum measures to ensure they will remain “secret”.

What is a “trade secret”?

From a legal standpoint, trade secrets protection in Thailand does not differ from international standards and the definition set forth by Article 39 of the TRIPS Agreement under the title “protection of undisclosed information”. Section 3 of the 2002 Trade Secrets Act provides that they are “trade information not yet publicly known or not yet accessible by persons who are normally connected with the information (…) the commercial values of which derive from its secrecy and that the controller of trade secrets has taken appropriate measures to maintain the secrecy”.

Trade secrets are thus a trade information that meets three cumulative criteria:

  • it is undisclosed: the information is not known by the public,
  • it has commercial value stemming from the fact that it is secret: the information made public will no longer offer the same competitive edge to its initial owner, and
  • it remains confidential because its owner has taken appropriate measures to safeguard its secrecy: such measures could be legal (e.g. confidentiality clauses and non-disclosure agreements in employment contracts) or technical (e.g. information accessible to only a few persons having the access code or specific privileges, information protected by security systems).

In a case from 2019, the IP & IT Court considered that a trade information protected by a password that was changed monthly by its owner could be viewed as a trade secret.[1] On the other hand, a simple confidentiality clause in an employment contract would not be seen as sufficient measure to ensure the non-disclosure of a trade secret.[2]

Why should trade secrets be protected?

We can identify two categories of trade secrets: business information (such as a clients’ list, marketing strategies) and technical information or processes characteristic of a “know-how”. The Coca-Cola recipe and Google search algorithm are famous examples of the latter and fostered the development and success of multinational companies, with no end in sight to their leading position in their respective market.

There lies the undeniable advantage of trade secrets: they can be protected indefinitely. However, they can remain so only if its holder has carefully thought through the procedures and mechanisms securing

its confidential nature, as early as possible. Similarly to other IP rights, prevention is key, but even more so for trade secrets. Indeed, once they are revealed or made public, they will most likely turn into simple “trade information” easily exploitable by competitors.

What constitutes an infringement of trade secret?

Sections 6 and 7 of the 2002 Trade Secrets Act regulate what constitutes an “infringement”: it is an act of disclosure, deprivation or use of the trade secret that meets three cumulative criteria:

  • the disclosure happened without the consent of the owner,
  • the disclosure was done in a manner contrary to honest commercial practices and
  • the infringer was aware (or had reasonable cause to be) that his/her act constituted a violation of honest commercial practices.

The law gives examples of acts contrary to honest commercial practices, ranging from breach of contract, infringement or inducement to infringe confidentiality, bribery, coercion, fraud, theft to espionage. Independent discovery, reverse engineering, honest use and disclosure by a state agency (if necessary for the protection of public health or for the benefit of other public interests) cannot be considered as infringement.

The time limit to bring infringement cases to court is three years from the date the infringement and the identity of the infringer is known, but not more than ten years from the date of infringement (Section 10).

What are the legal remedies and sanctions to trade secrets infringement?

Two types of civil remedies can be sought before the IP&IT Court by the trade secret owner (Section 8): an interim injunction to temporarily stop the infringement or a permanent injunction to stop the infringement and claim damages from the infringer. In the case of a permanent injunction, the trade secret holder may also request the destruction of the equipment used for the infringement (Section 11).

According to Section 13 of the 2002 Trade Secrets Act, the damages are normally evaluated based on the profits made by the infringer in connection with the infringement or, by default, as the court “deems appropriate”. Punitive damages can be determined by the court if it has clear evidence that the infringement happened “willfully or maliciously” and resulted in disclosing the secret to the public.

In case of a malicious disclosure, the infringer may also be liable for criminal offences punishable by a maximum of one year and/or a fine not exceeding 200,000 Thai baht (Section 33).

How to choose between trade secrets and patent protection?

Some IP assets may qualify as either trade secrets or patentable inventions. A company thus needs to evaluate its capabilities to maintain the secrecy of the invention. If they are insufficient or if it would be too cumbersome in practice to set up confidentiality protocols, the company might be better off protecting its invention through a patent, even though its protection will only last for 20 years. Moreover, if, once commercialized, the invention could be easily reverse engineered by competitors, a patent would again be the best option.

In some cases, companies might opt for a combination of both. Such has been the path picked by the Thai National Science and Technology Development Agency (NSTDA) who came up with a process to re-utilize some of the rubber waste generated during the process of transforming rubber latex. While the process developed was patented, the exact proportions of acidic compounds used in the process were kept secret. For more information, please see WIPO case study “Bridging the Gap from the Laboratory to the Market”, published on November 22, 2012.

In 2015, the Supreme Court confirmed that disclosing part of the invention through patent registration did not prevent a company from protecting undisclosed information related to the same invention with trade secrets.[1]

The short-lived trade secrets registration system in Thailand

From 2002 to 2013, companies had the possibility to register their trade secrets with the Thai Department of Intellectual Property (DIP). This system was set up to facilitate the use of evidence of trade secrets ownership in case of infringement. We can assume that, considering the sensitive “confidential” nature of trade secrets, this registration system did not encounter much success. Therefore, the DIP cancelled this procedure in July 2013.

If you filed an international trademark application via the Madrid system designating Thailand, in a great majority of cases, you will face a provisional refusal issued by the Thai Department of Intellectual Property (DIP) before your trademark is allowed for registration in Thailand.

Most commonly, this provisional refusal in Thailand is based on one or more of the following grounds:

  1. The goods or services listed in the application are deemed to be too “broad or vague” (Section 9 Trademark Act).
  2. Part of the trademark (a word or a device element) is deemed common to the trade and should be disclaimed by the applicant (Section 17 Trademark Act).
  3. The trademark is deemed to be similar to a prior trademark (pending or registered) used with the same kind of goods or services, which might confuse or mislead the public as to the ownership or origin of the goods or services (Section 17(2) Trademark Act).
  4. The mark is deemed not distinctive, either because the registrar considered that the words used are too generic, that the words or the device elements are descriptive of the characteristics or quality of the goods and services; or because the mark consists only of an acronym and/or numerals without any stylization (Sections 6 and 7 of the Trademark Act).

The first ground of refusal is almost systematic since the list of goods and services used by the DIP deviates largely from the Nice Classification. It is however easy to overcome, simply by filing an amendment of the specification in line with the requirements of the DIP, which means that the items should be especially specific and listed one by one.

The second ground of refusal is also easy to resolve by disclaiming the element(s) cited by the registrar as “common to the trade”. The disclaimer will prevent the owner of the trademark from claiming exclusive rights over the element(s) disclaimed, but her/his trademark will still be protected as a whole. In comparison to other South-East Asian countries, the Thai DIP strictly enforces the disclaimer requirement. Naturally, the applicant always has the option to challenge the registrar’s disclaimer request by filing an appeal before the Trademark Board, but the appeal procedure is rather lengthy and more costly.

The third and fourth grounds of refusal can only be overcome by filing an appeal against the registrar’s decision before the Trademark Board. The success rate of such a course of action should be determined on a case-by-case basis.

Currently, it takes around one year for the DIP to process an amendment of the specification or to record a disclaimer for incoming Madrid applications (for 3 to 6 months for standard applications filed in Thailand). The appeal procedure before the Trademark Board lasts 2 to 3 years.

These numerous obstacles encountered by foreign applicants using the Madrid Protocol should be carefully considered prior to choosing this path to register a trademark in Thailand. In many instances, filing a trademark application via a local representative would be more time and cost-effective. A minima, a local representative would (1) ensure that the list of goods and services complies with the requirements of the DIP; (2) advise on the necessity to include disclaimers in the application; and (3) conduct a trademark search to identify any existing similar prior marks.

Thailand accessed the Madrid Protocol in 2017. As such, trademark applications can be filed in and out of Thailand via the so-called “Madrid system”, allowing for the filing of one trademark in several designated signatory states with the payment of one set of fees transiting through WIPO.

In 2019, more than 8,000 applications designating Thailand have been filed via the Madrid System, which represented 38.5% of foreign applications in Thailand; in 2020, this number was down to 6,700 but represented 43% of foreign applications.

Incoming applications

A substantial number of incoming “Madrid applications” are objected by the Thai DIP due to Thailand’s specific requirements regarding the listing of goods and services. This generates additional cost for the applicants who should carefully select the items on the list of goods and/or services prior to file a trademark application in Thailand via the Madrid system.

If no objection is made by the registrar upon examination of the international application, the trademark will be published. If it is objected, a provisional refusal will be issued and forwarded to the applicant via WIPO.

If the basic application or registration is abandoned, rejected or cancelled, the applicant or trademark owner may file a national application in Thailand within 3 months. Provided that this application covers identical goods or services, the national filing date will be deemed to be the international registration date of the application or registration that has lapsed.

Outbound applications

An international application can be filed in Thailand by a person who is the owner of a pending application or registered trademark in Thailand, and who either (a) is a Thai national or juristic person incorporated in Thailand; (b) is domiciled in Thailand; or (c) has an industrial or commercial establishment in Thailand.

When filing a Madrid application in Thailand, the DIP will collect an additional fee of THB2,000 per application.

The owner of a trademark can authorize someone else to use their trademark(Trademark Licensing) in connection with some of or all the goods and/or services designated in the registration, with a license agreement.

To be effective in Thailand, this license agreement must be registered with the DIP, and include the conditions and terms of the use of the trademark and specify the goods or services with which the trademark is to be used by the licensee (Section 68 of the Thai Trademark Act). The registration of the license agreement takes 3 to 6 months.

The trademark owner must retain control over the quality of the goods or services provided under the license agreement. Failure to exercise such control can be cause for the cancelation of the license agreement by the Trademark Board, upon request by the registrar or a third party. The license may also be canceled by the Trademark Board if it is demonstrated that the use of the trademark by the licensee either confused the public or is contrary to public order, morality or policy (Section 72 of the Thai Trademark Act).

By default, unless otherwise provided in the license agreement (Sections 77 to 79/1 of the Thai Trademark Act):

  • The trademark owner will retain the right to use the trademark and to sign license agreements with third parties.
  • The licensee will be allowed to use the trademark in the entire country and with all the goods and services designated in the registration.
  • The licensee will not be allowed to transfer the agreement to a third party or conclude sub-license agreements.
  • Assignment or inheritance of the trademark will not revoke existing license agreements.

The rights to a pending trademark application or to a registered trademark might be assigned or transferred to another party (Trademark Assignment). This assignment or transfer needs to be registered at the DIP to take effect (Section 51). The following documents and information are required:

  1. The original notarized copy of the merger documents OR the original notarized Deed of Assignment, specifying the name, address and citizenship of the assignor and assignee, the details of the trademark application or trademark being assigned, the territory (Thailand) and the effective date of the assignment, signed by both assignor and assignee. If the assignment request is filed online, only an electronic copy of these documents is required.
  2. A copy of a notarized Power of Attorney executed by the assignee.
  3. For a registered trademark: the original Certificate of Registration. If the assignment request is filed online, only an electronic copy is required.

The official fee to register an assignment or transfer is THB2,000 per application or per trademark.

The assignment will be effectively registered within 3 to 6 months. For registered trademarks, a new Certificate of Registration in the name of the new owner will be issued.

The design registration process in Thailand takes approximately 16 to 24 months.

Formal examination

Following the filing of the application, the Thai Patent Office will take at least 6 months to undertake the preliminary examination of the application. If the application does not comply with the regulations, the applicant will be asked to amend the application within 90 days from receiving such request.

Publication

If the application complies with the formal regulations, the applicant will be asked to pay the publication fee (THB250) within 60 days of receiving the notice. If the applicant fails to pay the publication fee in these 60 days, a second (and last) notice will be issued, granting the applicant another 60 days to process the payment.

The application will then be published in the Thai Patent Gazette. Third parties may file an opposition against the application within 90 days from the publication date and present supporting documents within 30 days from the date of submitting the opposition. If no counterstatement is filed within 60 days from the day the applicant was notified of the opposition, the application will be deemed abandoned.

Substantive examination and grant

If no opposition is filed or if the opposition was unsuccessful, the examiner will perform the novelty examination of the application, which can last 6 to 8 months.

If the novelty examination is satisfactory, the applicant will then be required to pay the issuance fee (THB500) to obtain the design patent, within 60 days of receiving such notice. The design certificate will be issued in the weeks following the payment.

If the registrar considers that the design application does not meet the novelty requirements, the applicant can challenge this decision before the Patent Board within 60 days of being notified of the rejection of the application

Design Filing Requirement in Thailand

To file a design application in Thailand, the following Design Filing Requirement in Thailand need to be submitted to the Thai Department of Intellectual Property (DIP):

  1. A graphic representation of the design: there is no minimum or maximum number of drawings, but it is customary to submit 7 different views; the format does not matter, as long as the drawings are clear.
  2. An indication of the product with which the design will be used (only when it is not apparent from the design title or the drawings).
  3. A short claim.
  4. An original simply signed Deed of Assignment (DOA) if the applicant is not the creator OR an original simply signed statement of the applicant’s right if the applicant is the creator.
  5. A copy of a notarized Power of Attorney (executed by the applicant or their legal representative) appointing the agent in Thailand – this document will cover required information on the applicant (name, address and nationality or country of incorporation).

If the applicant is a Thai national/corporation, a Power of Attorney (simply signed – no notarization needed) can be submitted together with a signed copy of the applicant’s national identity card (for individuals) or of the company registration certificate issued in the last 6 months (for corporations).

Late filing of the DOA, statement of applicant’s rights and Power of Attorney is possible upon request, within 90 days from the date of filing the trademark application.

The official fee for filing the design application is THB250.

Unlike applications for invention patents that can be made for a group of closely connected inventions, a design application shall identify only one product with which the design is to be used. In addition, if the applicant wishes to protect more than one embodiment of the design, it is imperative to file a separate design application for each embodiment.

Online filing of design applications

The Thai DIP set up an online filing system, which can be used to file design applications and for most design prosecution matters. While only the electronic copies of the required documents need to be submitted, the original must be kept on hand in case they are requested by the registrar.

Additional requirements when claiming priority

For a design applications claiming priority of a foreign application, it is required to submit the original certified copy of the priority application. Such a priority-based application must be filed within 6 months of the filing date of the foreign application.

Assignment of priority right

Assignment of a priority right is possible for design applications, provided that the owner of the foreign application signs a deed of assignment with the applicant who wishes to file an application for the same design in Thailand. The original document needs to be submitted to the DIP.

We assist our clients in protecting their designs and enforcing related rights. For more information, advice or quotation, please do not hesitate to contact us at [email protected].

Formal and substantive examination

For Trademark Registration Procedure in Thailand, after filing the application, the registrar will check whether it complies with the formal and substantive requirements set out by the above-mentioned laws and regulations. If any inconsistency is found, the registrar will either:

  • Issue a refusal to register the mark if it is deemed prohibited, non-distinctive or similar/identical to prior marks (Sections 13 & 16), or
  • Issue an office action to request the applicant to amend the application (Sections 15 & 17) or provide additional documents (Section 12).

In both cases, the applicant will have 60 days from the date of receipt of the notification to answer the registrar:

  • An appeal can be filed before the Trademark Board against a refusal to register the mark or a request to disclaim any non-essential element of the mark. It takes around 2 to 3 years for the Trademark Board to issue a decision in appeal (see appeal flowchart in Annex).
  • An amendment needs to be filed to comply with the registrar’s order to amend the specifications, modify the address of the applicant or the agent on record, or disclaim any non-essential element of the mark, as the case may be. In practice, it takes 3 to 6 months to process the amendment, after which the application is published.

If the applicant fails to answer the registrar’s order within 60 days, the application is deemed abandoned.

Publication of the application and opposition proceedings

If the registrar has not raised any objection, the application will be published in the Thai Trademark Gazette within 9 to 10 months after the filing date.

The Trademark Gazette is published on the DIP website 4 times per month, in Thai language.[1]

The publication period will last 60 days, during which any third party may raise an objection against the suggested trademark on the following grounds (Section 35):

  • If they have better rights in the trademark than the applicant.
  • If the application does not comply with the Trademark Act.

Once the applicant is notified of the opposition by the registrar, they will have 60 days to issue a counterstatement, failing which the application will be deemed abandoned (Section 36).

In practice, the registrar will take about 1 year to issue its decision regarding the opposition, which will be notified to the applicant and the opponent. Both will have 60 days from the day they are notified to appeal the registrar’s decision before the Trademark registration Board, whose decision can further be appealed before the Court of Appeal for Specialized Cases, whose judgment can, in turn, be contested before the Supreme Court.

Registration of a trademark

If no opposition is raised during the publication period, the registrar will request the applicant to pay the registration fee, which is THB600 per item (for not more than 5 items in 1 class) and THB5,400 per class. The applicant has 60 days from the day of receipt of the registrar’s order to process the payment.

A Certificate of Registration can be obtained at the DIP simultaneously with the payment of the registration fee. The trademark will be registered for 10 years from the Thai filing date (or foreign filing date if priority is claimed), renewable indefinitely every 10 years.

The rights conferred to the owner of a registered trademark are as provided in the TRIP Agreement (Article 16), in essence, the exclusive right to use the trademark in connection with the designated goods and services and to prevent any third party from using a similar trademark for similar services and goods.

Single class or multi-class application?

Since 2016, trademark owners who wish to protect their trademarks across different classes of goods and services can do so by filing a single application. This procedure has the advantage of alleviating paperwork and reducing service fees at the different stages of the application process.

This might however raise issues in case a refusal is issued relating to one of the classes, as it will slow down the registration for the rest of the classes designated in the application.

Disclaimer good practice

It is advisable to file a disclaimer when the mark includes one or more words or device elements that are descriptive of the goods or services with which they will be used (or “common to the trade”), provided that the word(s) or shape(s) disclaimed constitute a non-essential part of the mark.

Filing a disclaimer together with the application will save cost and up to 6 months in the trademark registration procedure, as the registrar will most likely issue an office action to request the applicant to disclaim the words (whether in English, Thai or other languages) or shapes that refer to the goods or services or that are considered “too generic”.

As a result, the mark will still be protected as a whole, but the specific words or shapes disclaimed may be used by other parties providing similar goods or services. In other words, the owner of the mark will not have exclusive rights over the elements disclaimed.

We assist our clients in protecting their trademarks and other graphic signs used to distinguish their company, services or products. For more information, advice or quotation, please do not hesitate to contact us at [email protected].

The trademark renewal request can be filed within 3 months prior to the expiration date (Section 54). There is no document required unless the agent on record needs to be amended, in which case a copy of a signed and executed Power of Attorney needs to be provided.

Late trademark renewal is possible in the 6 months following the expiration date (grace period) and sanctioned with a 20% surcharge of the official fees due. The standard renewal fee is THB2,000 per item (if not more than 5 items per class) and THB18,000 per class.

A new certificate of registration will be issued 3 to 4 months after the renewal fee is paid.

A patent can be granted for a design if it meets the following two conditions:[1]

  • It must be new.
  • It must have an industrial application, which includes handicrafts.

Designs that are deemed contrary to public order or morality or that have been prescribed by a Royal Decree cannot be patented.

Under which circumstances is a design not “new”?

According to Section 57 of Patent Act B.E. 2522, there are 4 instances in which a design does not meet the novelty requirements:

  1. When it was widely known or used in Thailand by others before filing the design application.
  2. When it was disclosed in a document in Thailand or a foreign country before the filing date, with the exception of designs presented to the public during fairs, exhibitions or academic seminars within 12 months prior to the application date.
  3. When the design was published in Thailand or a foreign country before the Thai filing date of the application.
  4. When a design is similar to any design described above (already widely used or known, already disclosed or already published) to the extent that it could be seen as an imitation.

These provisions do not prejudice the right for the applicant (derived from the Paris Convention) to file a design application in Thailand within 6 months of the date of filing of the foreign application and claim the corresponding priority date.

We assist our clients in protecting their designs and enforcing related rights. For more information, advice or quotation, please do not hesitate to contact us at [email protected].

Thailand accessed the Paris Convention for the Protection of Industrial Property (1883) in 2008 and is also a member of the WTO. Therefore, the owner of a trademark that has been filed or registered in a country who also signed the Paris Convention and/or is a member of WTO, may claim the first foreign filing date as the filing date in Thailand, if the application is filed in Thailand within 6 months from the first filing date (Claiming Priority for Trademark Registration, Section 28).

In addition to the documents to Claiming Priority for Trademark Registration listed above, a separate form must be submitted at the time of filing (in Thai language), along with:

  1. The original certified copy of the foreign application (issued by the foreign trademark office); and
  2. The statement asserting that the former application has not been abandoned or withdrawn (original required).

Late filing of these two documents is possible upon request, within 90 days from the date of filing the trademark application.

The assignment of a priority right is not possible for trademark applications.

Basic filing requirements

If a patent/petty patent application is filed for the first time in Thailand, the following documents need to be submitted to the Thai Department of Intellectual Property (DIP):

  1. The abstract, claim and specification in Thai language, as well as the drawings, if any.
  2. The original simply signed Deed of Assignment if the inventor is not the applicant OR the original simply signed statement of applicant’s right if the inventor is the applicant.
  3. A copy of a notarized Power of Attorney (executed by the applicant or their legal representative) appointing the agent in Thailand – this document will cover required information on the applicant (name, address and nationality or country of incorporation).

If the applicant is a Thai national/corporation, a Power of Attorney (simply signed – no notarization needed) can be submitted together with a signed copy of the applicant’s national identity card (for individuals) or of the company registration certificate issued in the last 6 months (for corporations).

Late filing of the Thai translation, the DOA, the statement of applicant’s rights and the POA is possible upon request, within 90 days from the date of filing the patent application.

The official fee for filing is THB500 for patents and THB250 for petty patents.

The patent/petty patent application must be made for one invention only, or for a group of inventions that are so closely connected that they are part of the same concept. If during the examination, the registrar considers that the application covers several inventions that are not closely connected, the applicant may be required to separate the application into as many applications as inventions covered. The applicant must comply with the registrar’s request within 6 months following the date of receipt of the notice to keep the initial filing date as the filing date of each derived application.

Additional requirements when claiming priority

For a patent/petty patent application claiming priority of a foreign application, additional documents are required:

  1. The English translation of the application – optional but preferred.
  2. The original certified copy of the foreign application on which the priority claim is based.

Such priority-based application must be filed within 12 months of the filing date of the foreign application.

The original certified copy of the foreign application can be submitted within 90 days of the Thai filing date.

Assignment of priority right

Assignment of a priority right is possible for patent/petty patent applications, provided that the owner of the foreign application signs a deed of assignment with the applicant who wishes to file an application for the same invention in Thailand. The original document needs to be submitted to the DIP.

To register a trademark, an application form (“Kor.01”, in Thai language) must be filed by the applicant or their agent with an office or address in Thailand at the DIP or via the DIP online filing platform.

The following documents and information are required:

  1. A copy of a notarized Power of Attorney (executed by the applicant or their legal representative) appointing the agent in Thailand – this document will cover required information on the applicant (name, address and nationality or country of incorporation).

If the applicant is a Thai national/corporation, a Power of Attorney (simply signed – no notarization needed) can be submitted together with a signed copy of the applicant’s national identity card (for individuals) or of the company registration certificate issued in the last 6 months (for corporations).

  1. The specimen of the mark (word, picture, sound):
  • If it is a graphical representation, the specimen should be clear.
  • If it is in a word mark in a foreign language, the meaning and transliteration must also be indicated in Thai; if the registrar has any doubt regarding the translation provided, a certified translation may be required following examination.
  • For a 3D mark, 7 views must be submitted (front, back, left, side, top, bottom and perspective).
  • If the mark is a sound or contains a sound element, the sound should be described and a recording not exceeding 30 seconds should be provided.
  1. An enumeration of the goods and/or services to be used in connection with the prospective mark; multi-class filing is possible under Thai law.

Late filing of the copy of the Power of Attorney is possible upon request, within 90 days from the date of filing the trademark application.

The official filing fee is calculated based on the number of designated goods or services (if not more than 5 items per class, THB1,000/item) or the number of classes (THB9,000/class). All official fees are indicated on the DIP website.

While most formal elements of the application can be amended after filing (such as the address of the applicant), the list of goods and services can only be amended to include additional items at the registrar’s request (that is if the initial list does not comply with local practices), or to delete some items (Section 52). The specimen of the mark can also only be amended at the registrar’s request, usually to remove a specific element appearing on the logo.

Online filing of trademark applications

The Thai DIP set up an online filing system, which can be used to file trademark applications and for most trademark prosecution matters. While only the electronic copies of the required documents need to be submitted, the original must be kept on hand in case they are requested by the registrar.

Black & white or colors?

A mark registered in black and white or using a grayscale will be protected in all other color combinations (Section 45). On the other hand, a mark registered in two or more colors will only be protected with the colors claimed. Therefore, it is advisable not to register the mark in color to provide the widest protection possible to the mark.

Classification of goods and services in Thailand

Although Thailand has not endorsed the Nice Agreement on the International Classification of Goods and Services (1957), it uses the 11th edition of the Nice classification as a guideline, with some peculiarities.

As a result, many provisional refusals are issued against incoming Madrid applications since the designated goods and/or services are not a perfect match with the list used by the Thai Trademark Office. This significantly slows down the registration process for trademark applications introduced through the Madrid system. For instance, the item “pharmaceutical preparations” (in Class 5) will not be accepted, as it is considered too broad. Examples or acceptable items would be “pharmaceutical preparations for slimming purposes” or “…for skin allergies”.

An invention must meet the following three widespread substantive requirements to be registered as a patent in Thailand (Sections 5 to 8 of Patent Act B.E. 2522):

  • It must be new, i.e., not part of the state of the art.
  • It must be industrially applicable, i.e., made or used in any industry (crafts, agriculture, commerce, etc.).
  • It must involve an inventive step, i.e., not being obvious to a person “ordinary skilled in the art”.

For petty patents, the requirements are less stringent as only the two first criteria are to be met, i.e., the invention does not need to involve an inventive step. An invention cannot be the object of both a patent application and a petty patent application, but a patent application can be converted into a petty patent application and vice versa. If a patent and a petty patent application are filed for the same invention, only the petty patent application will be considered by the DIP.


What constitutes the “state of the art”?

By and large, the state of the art refers to the existing knowledge and inventions already known or used in a given field. More specifically, Section 6 of Patent Act B.E. 2522 gives a list of inventions that cannot be considered as “new” under Thai law:

  • An invention widely known or used by others before the filing date or for which a patent has already been granted in Thailand.
  • An invention described in a document or publication disclosed to the public in Thailand or abroad (before the filing date) – unless such disclosure was due to illegal appropriation of the invention or was made during an international/official exhibition that took place in the 12 months preceding the Thai filing date.
  • An invention for which a patent/petty patent application was:
    • Filed abroad more than 18 months before the Thai filing date.
    • Filed abroad and already published.
    • Filed abroad and already resulted in the grant of the patent/petty patent.

These provisions do not prejudice the right for the applicant (derived from the Paris Convention) to file a patent/petty patent application in Thailand within 12 months of the date of filing of the foreign application and claim the corresponding priority date.

Inventions outside the scope of the Patent Act B.E. 2522

The inventions covering the following subject matters cannot be the object of a patent/petty patent:

  • Naturally occurring microorganisms and their components.
  • Scientific or mathematical rules or theories.
  • Computer programs.
  • Methods of diagnosis, treatment or cure of human and animal diseases.
  • Inventions contrary to public order, morality, health or public welfare.
