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.

  • 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.

  • 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

Indonesia has updated its fee framework for intellectual property (IP)-related government services, with implications for IP owners, licensees, lenders, digital platforms, and businesses operating in the country. Government Regulation No. 30 of 2026 on Types and Tariffs of Non-Tax State Revenue Applicable to the Ministry of Law (GR 30/2026) was promulgated on July 2, 2026, and will take effect on August 1, 2026. Key Takeaways GR 30/2026, which replaces the relevant IP service fees under Government Regulation No. 45 of 2024, reorganizes the fee schedule into separate categories for copyright, industrial designs, patents, layout designs of integrated circuits, trade secrets, trademarks, geographical indications, IP enforcement, and other categories. The most commercially relevant changes include a new copyright recordation tariff exemption for songs and music, higher fees for several trademark and geographical indication services, new IP enforcement service fees, and a new fee type for registration of fiduciary security over IP rights objects. In addition, this is the first major update for trademark fees in approximately 10 years. GR 30/2026 is significant not only as a fee update but also as a further indication of Indonesia’s increasing recognition of IP as a financeable commercial asset. By expressly assigning fees to the registration of fiduciary security over IP rights objects, the regulation places IP-backed collateral filings within the Ministry of Law’s administrative service framework. While GR 30/2026 does not create a new secured-transactions regime, this development is relevant for lenders, borrowers, and IP owners structuring financing arrangements secured by trademarks, patents, copyrights, industrial designs, or other registrable IP rights in Indonesia. Copyright: New Fee Exemption for Songs and Music Recordation For copyright, GR 30/2026 creates a fee-exempt category for recordation of works or related-rights products for songs or music, while maintaining a separate category for other works and related-rights products. It

Thailand’s Ministry of Digital Economy and Society (MDES) published a notification establishing an expedited court-ordered takedown mechanism for online content in cases of “urgent necessity.” The notification, which was issued on July 17, 2026, under the Computer Crime Act B.E. 2550 (2007), as amended, took effect the following day. It significantly expands the categories of content subject to rapid government-initiated removal. Content Categories Subject to Takedown The notification defines “urgent necessity” (section 20, paragraph 5, of the Computer Crime Act) as circumstances where any delay in suppressing computer data may impact national security, religion, the monarchy, good morals, social culture, or public order. In this regard, it establishes four broad categories of content: Computer Crime Act offenses. National security offenses. IP and other criminal offenses, where it is contrary to public order or good morals and a competent officer has requested its suppression. Content contrary to public order or good morals, a broad residual category encompassing 14 subcategories approved by the Computer Data Screening Committee. The fourth category is the most expansive. Its 14 subcategories include: Content defaming, mocking, satirizing, or devaluing the monarchy. Online gambling advertising or facilitation. Offering illegal firearms for sale. Offering baraku (hookah) products or e-cigarettes for sale. Offering cannabis inflorescences or processed cannabis products for sale. Advertising or soliciting prostitution. Content inciting violence, hatred, or social division. Unauthorized overseas employment advertising. Offering boiled kratom juice for sale. Online sale or advertising of alcoholic beverages. Content satirizing or degrading Buddhism. Money lending at interest rates exceeding legally prescribed limits. Advertising or disseminating information about surrogacy services. Forgery of documents, cards, or official documents. Enforcement Procedure In cases of urgent necessity, a competent official assigned by the MDES permanent secretary must file a petition with supporting evidence to the court with jurisdiction, requesting an order to

Ambush marketing refers to a strategy in which a business associates itself with an event, campaign, or brand without paying for official sponsorship rights. The tactic is most visible in sports, concerts, and festivals, where official sponsors have invested substantially for exclusivity. Ambush marketers may use suggestive wording, event-themed imagery, athlete endorsements, venue-adjacent promotions, or social media campaigns implying a commercial connection with the event. Common Forms of Ambush Marketing Ambush marketing typically takes one of the following forms: Direct ambushing: using event names, logos, or mascots suggesting authorization Coattail ambushing: sponsoring an athlete or broadcaster connected with the event Subtle ambushing: themed advertising, venue-adjacent campaigns, or similar visual cues The legal analysis in each case turns on whether the marketing crosses from permissible event-based advertising into infringement, passing off, deception, or wrongful exploitation of goodwill, and the risk assessment is necessarily fact-specific. Thailand has no dedicated ambush marketing statute, so legality depends on execution. A campaign that merely comments on a public event may be permissible, but one that uses protected marks, creates consumer confusion, misrepresents sponsorship status, or makes unsubstantiated claims may trigger liability under various Thai laws, as laid out below. Ambush Marketing and Thailand’s Trademark Act The Trademark Act B.E. 2534 (1991) is the primary tool for addressing campaigns that use registered trademarks, event names, logos, mascots, or confusingly similar signs. The law gives registered trademark owners the exclusive right to use their mark for registered goods, and infringement risk arises when a nonsponsor uses an event mark or a confusingly similar sign in advertising. Even referential or playful use may create liability if it causes public confusion as to sponsorship or commercial connection. The law also preserves passing-off claims for unregistered marks. This matters because event names, taglines, or mascots may not always be

When Decree No. 186/2026/ND-CP (Decree 186) takes effect on July 15, 2026, it will introduce the most significant reform of Vietnam’s administrative IP enforcement framework since Decree 99/2013/ND-CP was issued in 2013. These changes are expected to make administrative enforcement faster, more accessible, and better suited to the realities of modern IP disputes. Below are the principal reforms and their practical implications for rights holders and enforcement practitioners. The End of Notarization and Consular Legalization Among the most welcome procedural changes is the abolition of the notarization and consular legalization requirement for powers of attorney (POA) submitted in administrative enforcement proceedings. Under the previous regime, foreign rights holders were generally required to execute a POA, then have it notarized and consular legalized (if seeking customs recordal). In practice, this process frequently delayed enforcement by four to eight weeks, often long enough for infringing goods to disappear before authorities could intervene. Decree 186 removes this bottleneck, now requiring only an original or certified copy of the POA. If the document is in a foreign language, a Vietnamese translation is sufficient, provided it is certified by a competent authority or confirmed by the authorized Vietnamese IP representative. Consular legalization and notarization are no longer required. For rights holders, the practical impact is substantial. Administrative enforcement files that previously took weeks to prepare can now be completed in a matter of days, allowing much faster responses in time-sensitive matters such as warehouse raids, border interventions, and trade-fair enforcement. The decree also introduces a useful administrative simplification. Where an original POA has already been submitted to the same enforcement authority and remains valid, applicants may rely on a copy of that earlier submission by identifying the previous case file. This eliminates unnecessary duplication for rights holders pursuing multiple enforcement actions before the same
