EXPERIENCE

  • Assisted an American oncology treatment technology company with IP and consultancy service licensing of their groundbreaking proton therapy diagnosis and delivery system to a Thai medical device company, primarily for use in oncology treatment centers in Thailand. Once deployed, the technology could potentially contribute to significant improvements in cancer diagnosis and treatment in the nation.
  • Represented a major pharmaceutical company by liaising with the Thai FDA on marketing compliance issues, verifying that the client’s marketing activities were in compliance with the complex regulations governing pharmaceutical practice in Thailand, and preventing and mitigating potential risk and loss to the client.
  • Handling the entire trademark and patent portfolio in Cambodia, Indonesia, Laos, Myanmar, Thailand, and Vietnam for one of the world’s largest pharmaceutical and life science companies, including the transfer of the entire agribusiness portfolios of one of their competitors following their acquisition of the competitor in 2018.
  • Assisted hundreds of global franchisors on localizing their franchise agreements and facilitating their market entry into Cambodia, Indonesia, Laos, Myanmar, Thailand, and Vietnam, including many of the world’s best known convenience store, food and beverage, and retail brands.
  • Appointed by the chemical flagship subsidiary of one of Thailand’s largest conglommerates as the sole firm to handle the filing of recordals of assignment and name changes after the purchase of a massive patent portfolio from an affiliated company in the US.
Effective enforcement maximizes the benefits of IP registration.

Tilleke & Gibbins continues to lead the way in developing new IP enforcement strategies. Our services in this area include investigation, staff training, market surveys, comprehensive turnkey anticounterfeiting and antipiracy campaigns, preventive strategies, civil and criminal action, police/excise/customs raids and seizure actions, negotiation and dispute resolution, mediation, arbitration, public relations/press management, government lobbying, law enforcement liaison, and cancellations.

Our investigators are constantly in the field, on the lookout for infringements, and employ creative strategies to track down traders, distributors, and manufacturers of infringing and counterfeit goods.

 

EXPERIENCE

  • Tilleke & Gibbins regularly organizes product identification training sessions across Southeast Asia for our IP practitioners and clients to come together and train government officers on how to differentiate genuine products from counterfeit products for some of the world’s leading brand owners. Through these events, we help support educational programs, enhance border control measures, strengthen IP protection for our clients, and build collaborative relationships with officials from the operational to the executive level.
  • Assisted a leading manufacturer of household and oral care products in taking action against imported shipments of potentially dangerous counterfeit healthcare products from China into Laos, Thailand, and Myanmar, working in collaboration with the customs department of each country to track and seize the shipments.
  • Assisted a world-renowned coffee company in the client’s project to eliminate all online counterfeit merchandise in Cambodia, Laos, and Thailand. We regularly conduct comprehensive online market survey investigations, identify infringing online sellers, and subsequently send cease-and-desist notices, initiate raid actions in cooperation with local authorities, and send take-down notices for websites containing infringing content in an effort to entirely remove counterfeits from the market.
  • Represented a client in a landmark website takedown request, based on online trademark infringement, made directly to Thailand’s Department of Intellectual Property under the Computer Crimes Act. This was the first request of its kind made to the DIP in Thailand, and the successful takedown opened an efficient new avenue for fighting online infringement in the jurisdiction.
  • Acted for a leading agricultural machinery and product manufacturer in coordinating a raid action with the Cambodian Counter Counterfeit Committee (CCCC), which ended up being one of the largest raids in Cambodia to date in terms of number of products seized—upwards of 30,000 counterfeit products infringing our client’s trademarks.
Our clients deserve the best representation in IP disputes.

Our IP litigation team handles a full range of criminal and civil IP disputes, including disputes related to patents, trademarks, copyrights, trade secrets, trade names, infringement, invalidity, cancellation, appeals of decisions by the trademark and patent offices, and other commercial disputes involving IP assets such as franchising and distributorship. Tilleke & Gibbins has successfully secured rare Anton Piller orders and emergency injunctions from Thailand’s Central Intellectual Property and International Trade (IP&IT) Court.

EXPERIENCE

  • Won a landmark ruling from the Thai Central Intellectual Property and International Trade (IP&IT) Court for a leading Japanese automotive company in a design patent infringement case involving multiple infringing companies. This challenging case required the combined legal efforts of our IP litigation, enforcement, and in-house investigation teams in filing the case, requesting preliminary measures, liaising with authorities in raids and seizures, conducting market surveys to obtain evidence, and other work. Our teams ultimately secured a victory for our client, with the court awarding them the largest civil lawsuit compensation amount for a design patent infringement case to date in Thailand.
  • Achieved a victory for a German multinational life sciences company in one of the first civil patent litigation cases in Vietnam. In the case, we brought a patent infringement charge against a local chemical manufacturer, with the court later ruling in our client’s favor.
  • Represented Thailand’s largest cable and satellite television provider and sole Thai licensee of the broadcast right to the FIFA World Cup 2018 in a court case against subsidiaries of its main competitor, in complex copyright litigation relating to the broadcast of the World Cup under Thailand’s “must-carry” law. Our swift action and high-level knowledge resulted in an emergency injunction preventing the opposition parties from broadcasting the world cup through their digital channels, ceasing the infringing broadcasts early in the competition.
  • Won a historic judgment from the IP&IT Court for a global technology leader against former employees who misappropriated our client’s tremendously valuable trade secret technology. In the IP&IT Court decision, our client was awarded an injunction against use and disclosure of its trade secret technologies, including machines, processes, and information. Our client also received substantial damages and recovery of legal fees amounting to over THB 52 million. The Supreme Court also affirmed the IP&IT Court’s ruling, in addition to ordering the defendants to destroy their infringing equipment and pay damages to our client.
  • Assisting a major European pharmaceutical company, which discovered two locally made drugs in Vietnam contained an active ingredient in a form for which they hold an active patent. This unprecedented case marks the first time that infringement of a patented crystalline form of a compound has arisen in Vietnam; all other pharmaceutical patent disputes had concerned the patented compound itself. This is also the first patent case in Vietnam in which a foreign expert opinion was allowed to be used to support local expert opinions.
We combine technical training and expertise with deep knowledge of patent law.

Tilleke & Gibbins handles a full range of work in relation to patents, petty patents, and designs. This includes patent and design searches, registration and prosecution of patents, petty patents, and designs throughout Southeast Asia and worldwide, recordal of changes/assignments, annuity payments, oppositions, cancellations, watch services, infringement assessments, freedom-to-operate analyses, validity and invalidity assessments, and registration of patent license agreements. 

With a rise in litigation and invalidation actions in the region—some based on issues related to translations and terminology—it is increasingly important that patent translations be of the highest accuracy and in accordance with local technical terminology and conventions. In this regard, Tilleke & Gibbins has built an in-house translation team featuring experienced translation managers and technical translators. Our technical translators include professionals with engineering (mechanical, computer, electrical, etc.), medical, biology, and pharmacy degrees. Additionally, our translation process includes careful review by translation managers and patent attorneys prior to filing.

  • Handled a significant project for a major industrial group in Thailand involving the change in ownership of the firm’s patents. We verified 205 patents and filed recordals for 150 patent applications pertaining to assignment, merger, change of legal entity, and change of name and address.
  • Appointed to represent the Thai National Innovation Agency, under the Ministry of Science and Technology, in their Mind Credit funding program to protect the intellectual property of Thai SMEs. We are currently assisting a number of fund recipients in registering patents across the region.

  • Handling the entire trademark and patent portfolio in Cambodia, Indonesia, Laos, Myanmar, Thailand, and Vietnam for one of the world’s largest pharmaceutical and life science companies, including the transfer of the entire agribusiness portfolios of one of their competitors following their acquisition of the competitor in 2018.

EXPERIENCE

  • Handling over 100,000 active trademark matters in Cambodia, Indonesia, Laos, Myanmar, Thailand, and Vietnam, for more than 14,000 brand owners, and directly filing an average of 7,500 new applications in each jurisdiction.
  • Represented a Japanese pharmaceutical company, a Korean automotive manufacturer, a Finnish technology company, and a Japanese consumer goods company in registering their sound marks after a ministerial regulation allowed for such registration in late 2017, and was the first law firm in Thailand to successfully register such marks.
  • Conducted international registration of a trademark shortly after the Madrid Protocol became effective in Thailand in late 2017, and was the first law firm in Thailand to register through the Madrid route.
  • Became the first firm to successfully re-file a trademark during the soft-opening period of the Myanmar Department of Intellectual Property (DIP) under the country’s new trademark law.
  • Handling the entire trademark and patent portfolio in Cambodia, Indonesia, Laos, Myanmar, Thailand, and Vietnam for one of the world’s largest pharmaceutical and life science companies, including the transfer of the entire agribusiness portfolios of one of their competitors following their acquisition of the competitor in 2018.

  • Acting as the sole external IP firm for a leading global manufacturer of energy drinks, which has trademarks registered in over 150 countries. We manage the client’s full range of trademark needs, including registrations, renewals, recordals, assignments, license agreements, and enforcement measures. We continually assist the client in its goal of becoming a global brand by effectively managing their global IP portfolio, and ensuring strong protection as the brand grows internationally.
  • Successfully registered a three-dimensional mark used as jewelry packaging for a French luxury goods conglomerate. The registration of three-dimensional marks in Vietnam is quite rare, and extensive evidence of fame and use is required. Our work may pave the way for more 3-D trademarks to secure registration in Vietnam, and has also contributed to the government’s understanding of 3-D marks

Recycling, upcycling, and refill-packaging models are now widely promoted as ways to reduce waste, lower carbon emissions, and respond to consumer demand for sustainable products. However, complications arise when these environmentally driven trends intersect with intellectual property law—particularly where reused or altered packaging continues to display third parties’ registered trademarks. Adding to this complexity, Thailand’s draft Sustainable Packaging Management Act aims to introduce new environmental compliance obligations that businesses must navigate alongside existing trademark concerns. Recycling and upcycling packaging may infringe trademark rights, especially in cases not protected by the first-sale doctrine—the principle that a trademark owner’s rights over a particular mark-bearing product end once the owner first sells it. Furthermore, even refill packaging carries legal risk due to specific statutory prohibitions under Thai law. Compounding these challenges, the draft Sustainable Packaging Management Act will impose extended producer responsibility (EPR) obligations on manufacturers and brand owners, requiring them to manage packaging throughout its lifecycle. These overlapping legal frameworks could deter manufacturers from pursuing ESG-aligned business models unless businesses understand how to navigate both trademark and environmental requirements. Under Thai law, this issue remains uncertain because the Trademark Act does not expressly codify the first sale doctrine, also known as the exhaustion of trademark rights. Generally, this doctrine provides that once a trademark owner has lawfully sold goods bearing its trademark, the owner’s right to control further resale of those particular goods is exhausted. The rationale is that the owner has already received commercial benefit from the first authorized sale; therefore, the purchaser should be free to resell or otherwise dispose of the goods. Although the doctrine is not expressly codified in the Trademark Act, Thai courts have recognized it in relation to genuine goods and parallel imports, as seen in a Supreme Court Judgment No. 2817/2543 in which the

Indonesia’s regulation on reporting online intellectual property (IP) infringement provides comprehensive procedural guidance for IP rights holders and their licensees in reporting online infringement complaints. Issued in December 2025 by the Ministry of Law as Regulation No. 47 of 2025 regarding Handling of Intellectual Property Infringement Reports in Electronic Systems, this regulation covers all types of IP rights. It also specifies documentation when reporting infringement, and lays out the procedures for examination, verification, and enforcement actions. Submission of Complaints Complainants may submit reports through the online system of the Directorate General of Intellectual Property (DGIP) or in person at the DGIP office. Complaints may also be filed through an authorized proxy. Under the regulation, complainants are required to provide the following information and documents: Personal details of the complainant; Brief description of the protected work or subject matter (i.e., type of IP and name or address of the infringing website, portal, account, or application, or a link to the location of the infringing content); Complete description of the alleged infringement; Certificate of registration or recordal of the relevant IP; Recordal of IP license agreement, if any; and Other supporting evidence. Verification and Examination Process Upon receiving a complaint, the responsible formality officer may request clarification or additional supporting documents. In the latter case, the complainant must then submit the necessary administrative documents within 14 days of the notification date. Once the documentation is deemed complete and sufficient, the case will be formally registered. Subsequently, the DGIP will establish a verification team to handle online IP violations, which will include the Civil Servant Investigator (PPNS), the Ministry of Communication and Digital Affairs, experts with relevant expertise in IP, and representatives from related associations such as AVISI (Indonesian Video Streaming Association). After examining the report, the team will prepare the Minutes

Customs recordation is an enforcement mechanism in Myanmar that enables intellectual property (IP) rights holders to seek prevention of the cross-border movement of infringing goods. The enactment of Myanmar’s IP laws in 2019 has enabled customs recordation for registered marks and copyrights under the Trademark Law 2019 and the Copyright Law 2019. By contrast, the Patent Law 2019 and the Industrial Design Law 2019 do not provide a practical framework for customs recordation, and accordingly such rights are not subject to the customs recordation regime. Under the Trademark Law 2019, rights holders may apply for customs recordation and may also ask the Customs Department to suspend the release of goods suspected of bearing counterfeit marks. Likewise, the Copyright Law 2019 allows for customs intervention in relation to pirated works. These provisions reflect Myanmar’s gradual alignment with international standards on border measures, although the implementation framework remains at a relatively early stage of development. Customs Recordation Pursuant to the Trademark Law 2019 and the Copyright Law 2019, the relevant authorities have issued customs rules concerning the protection of registered marks and copyrights. In practice, the process generally begins with the submission of an application to the Customs Department together with supporting documentation. This typically includes proof of registration in Myanmar; details of the rights holder, applicant, and any authorized representative; and a comprehensive description of the genuine goods. Product identification materials—such as photographs, packaging samples, and distinguishing features—are particularly important in helping customs officers identify suspected infringing goods. A recordation remains valid for two years from the date of approval. It may be renewed for additional two-year terms, provided that the renewal application is filed within the thirty days prior to expiry for marks and up to thirty days in advance of the expiry date for copyrights, in accordance with

Patent enablement requirements are provided under Article 102 of Vietnam’s Law on Intellectual Property (IP Law). In particular, a patent specification must “fully and clearly disclose the nature of the invention to such an extent that, based on the specification, a person having ordinary skill in the relevant art can implement the invention.” In pharmaceutical and biotechnology patents, this requirement is more complicated and subject to more rigorous assessment. The Patent Examination Guidelines (Guidelines) of the Intellectual Property Office of Vietnam (IP Office) were amended in March 2026 to introduce Annexes III and IV for the pharmaceutical and biotechnology sectors, in which Annex III provides detailed guidelines on the assessment of specification requirements. These amendments were made under a project for strengthening capacity in industrial property examination between the Japan International Cooperation Agency (JICA) and the IP Office. Annex III provides detailed instructions on how examiners assess enablement in a pharmaceutical or biotechnology application, and offers examples of acceptable and unacceptable descriptions with regard to the enablement aspect. Enablement Requirements in Pharma and Biotech Patents Article 12.7 of Circular 10/2026/TT-BKHCN (Circular 10) adds to the requirements of Article 102 of the IP Law that the description must demonstrate the novelty, inventive step, and industrial applicability of the technical solution. For pharmaceutical composition subject matters, Article 12.9 of Circular 10 sets out that the description must present the results of clinical trials and/or the pharmacological effects of the claimed pharmaceutical composition, and must include at least the following information: Substance/mixture used. Testing method (system) employed. Information on the test results. Correlation between the pharmacological effects obtained from the tests and the application of the pharmaceutical product in the prevention, diagnosis, and treatment of diseases. The Guidelines note that pharmacological study results should be presented in a quantified manner, and pharmacological
