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.

  • Retained to assist world-leading Japanese automobile and motorcycle manufacturers and distributors to draft new patent specifications and handle the filing of several of international patent applications under Patent Cooperation Treaties.
  • 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.

  • 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.

  • 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.

  • 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

Myanmar’s first-to-file trademark registration regime under the Trademark Law 2019—which became fully operational in April 2023—provides mark owners with enhanced legal protection compared with the country’s former system. Correspondingly, the current system imposes more rigorous statutory requirements for obtaining, maintaining, and enforcing rights in marks. In this first-to-file trademark registration system, however, evidence of use remains particularly significant, as it may establish acquired distinctiveness, support a claim that a mark is well-known, and strengthen the owner’s position in both registration and enforcement proceedings. Accordingly, it can be said that this framework is underpinned by three key concepts: distinctiveness, well-known status, and, importantly, use of the trademark. Trademark Distinctiveness Under the Trademark Law, signs that lack distinctiveness are generally ineligible for mark protection. These signs include generic terms, basic shapes, unstylized single letters or numerals, and signs that merely describe the kind, quality, quantity, intended purpose, value, geographical origin, production time, or other characteristics of the relevant goods or services. However, a mark that would otherwise be refused on distinctiveness or descriptiveness grounds may be registrable if it has acquired distinctiveness through its use prior to the filing date. To show this, the applicant must demonstrate that the mark became distinctive to relevant consumers through continuous, exclusive, and good-faith use in trade within Myanmar. The burden of proving acquired distinctiveness rests with the mark owner. Accordingly, sufficient evidence demonstrating both use of the mark and the level of consumer recognition attained should be prepared in advance. Well-Known Mark Criteria Myanmar’s Trademark Rules, which govern the substantive examination of mark registration applications, establish criteria for determining well-known marks, aligned with international standards. Where an applicant claims well-known status—whether to overcome a refusal on relative grounds or to oppose a third party’s registration—the registrar will assess the claim based on the following

On August 23, 2026, Vietnam’s National Assembly passed Law No. 11/2026/QH16, amending the country’s Customs Law with effect from March 1, 2027. The amendments represent a substantial reform of Vietnam’s customs-based intellectual property enforcement regime. The reforms come amid considerable external pressure. In its 2026 Special 301 review, the US Trade Representative (USTR) designated Vietnam a “priority foreign country,” citing widespread counterfeiting, weak border enforcement, limited ex officio customs powers, and the absence of controls over goods in transit. Vietnam’s legislative response signals a commitment to bringing its border enforcement practices into line with international expectations. For IP rights holders operating in or through Vietnam, the amended law introduces several tools that substantially strengthen enforcement options at the border. Closing the Transit Gap One of the most consequential amendments is the extension of IP-related customs enforcement to goods in transit. Previously, Vietnam’s customs regime applied IP controls only to goods being imported or exported, a gap the USTR had specifically identified as enabling infringing goods to pass through Vietnamese ports with impunity. Vietnam’s geographic position as a logistics hub for Southeast Asia means that substantial volumes of goods transit its ports and free-trade zones. Extending enforcement to cover these shipments brings Vietnam closer to the standard set by the EU’s customs enforcement regulation and addresses a longstanding concern of multinational brand owners whose goods are frequently counterfeited in the region. Strengthened Suspension and Ex Officio Powers The amended law introduces a dual-track suspension mechanism (Article 73(2)). Customs authorities will suspend clearance upon request by an IP rights holder (or authorized representative) who provides evidence of IP ownership, evidence of infringement, and a financial guarantee. Customs can now proactively suspend clearance on an ex officio basis if, during inspection and monitoring, they discover “clear grounds” to suspect that imported, exported,

Indonesia’s Constitutional Court (Mahkamah Konstitusi) has reinstated a key provision limiting pharmaceutical patent protection, signaling a renewed commitment to balancing patent rights with public access to medicines. In its ruling to Case No. 255/PUU-XXIII/2025, the court partially granted a petition for judicial review of Law No. 65 of 2024, which had amended the country’s Patent Law, and ordered the restoration of a provision that had excluded certain pharmaceutical inventions from patentability. The decision took effect immediately upon its pronouncement at the court’s plenary session on August 28, 2026. Background The petition challenged the removal of article 4(f) from Law No. 13 of 2016 concerning Patents (Patent Law), as amended by Law No. 65 of 2024. Article 4(f) had excluded from patentability certain inventions relating to new uses of known substances. The petitioners argued that removing this provision would open the door to patent protection for second medical use inventions and facilitate patent evergreening—practices that can extend exclusivity periods, delay generic market entry, and reduce public access to affordable medicines. The petitioners included several patient advocacy and public-interest organizations: the Indonesian Dialysis Patients Community Association, the Indonesian Association of Drug Abuse Victims (PKNI), the Indonesian Pulmonary Hypertension Foundation (YHPI), the Rekat Peduli Indonesia Foundation, and the Indonesian Positive Women’s Association (IPPI), along with the Indonesia for Global Justice Association and four individual petitioners. The petitioners also challenged the constitutionality of the phrase “interested party” in article 70(1) of the Patent Law, arguing that it should be construed expressly to clarify who has standing to appeal a decision to grant a patent before the Board of Patent Appeal, and to allow a broader range of parties—such as patent holders, licensees, consumer organizations, prosecutors, aggrieved third parties, and others who may suffer direct or indirect harm from the grant of a patent—to

Thailand and China have a longstanding and significant trade relationship, which increasingly extends to e-commerce and digitally enabled supply chains. While these channels create new opportunities for businesses to reach consumers across borders, their growth also brings greater exposure to intellectual property (IP) infringement across jurisdictions and online platforms. Effective cooperation between the two countries’ enforcement authorities has therefore become increasingly important. To strengthen cooperation in this area, Thailand and China signed a memorandum of understanding (MOU) on IP enforcement in Beijing on July 20, 2026, during the Thai prime minister’s official visit to China. Officially titled “Memorandum of Understanding Between the State Administration for Market Regulation of the People’s Republic of China and the Ministry of Commerce of the Kingdom of Thailand on Cooperation in the Field of Intellectual Property Enforcement,” the MOU forms part of a broader bilateral agenda covering industrial and supply chains, participation by micro, small, and medium-sized enterprises (MSMEs), cooperation associated with the ASEAN–China Free Trade Area 3.0, and progress on the registration of Thai geographical indications in China. The MOU establishes a bilateral framework for cooperation and coordination in five broad areas: Strengthening dialogue in IP enforcement; Enhancing information sharing; Facilitating the enforcement of IP rights in cases arising in the parties’ domestic markets and on online platforms, in accordance with their respective domestic laws; Promoting cooperation in IP enforcement training and human resource development; and Undertaking other cooperation activities agreed upon by both sides. The Department of Intellectual Property (DIP) will serve as the principal coordinating agency for Thailand, while the Bureau of Law Enforcement and Inspection in China’s State Administration for Market Regulation (SAMR) will serve in that role for China. The framework is particularly relevant to the growth of e-commerce, as it covers infringement in the domestic markets and on
