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.

EXPERIENCE

  • 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.
  • Representing one of the world’s leading chemical manufacturers on patent matters in Indonesia, in addition to managing a portion of the client’s IP portfolio in 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.

  • 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

RELATED INSIGHTS

When considering a franchise, many people first think of a restaurant, retail chain, or service outlet. From a legal perspective, however, the foundation of every franchise lies in the right to use a brand, which is typically granted through a trademark license. Trademarks are often the most valuable assets in a franchise system. Through a trademark license, a franchisor authorizes a franchisee to use its trademarks, logos, and branding while maintaining control over how the brand is presented to customers. The Role of Trademarks in Franchise Businesses Under the Trademark Law 2019, a mark is defined as a sign that is capable of distinguishing the goods or services of one undertaking from those of others in the course of trade. This distinguishing function is particularly important in a franchise arrangement, where the franchisee’s use of the franchisor’s trademark allows consumers to recognize the source, quality, and reputation of the business. In this way, trademarks help preserve brand identity, strengthen market recognition, and protect the commercial value of the franchise system. Legal Foundation for Franchise Brand Protection Myanmar presently does not have a specific statutory framework governing franchise arrangements. As a result, franchise agreements are generally regulated under the broader applicable legal framework, including the Contract Act 1872, the Trademark Law 2019, the Competition Law 2015, the Consumer Protection Law 2019, and the relevant implementing rules and regulations. The licensing of trademarks within a franchise arrangement is particularly governed by the Trademark Law 2019. Franchisors should ensure that the trademarks intended to be licensed to franchisees in Myanmar are registered under the Trademark Law 2019 and that the relevant trademark license is properly recorded with the Intellectual Property Department (IPD). Trademark License Recordal Under the Trademark Law 2019, the owner of a registered trademark may grant a license to another

It is generally understood that patents are granted for new designs that have not been widely known or used in Thailand and not been disclosed anywhere prior to the date of the patent application. It is trite law that design law protects the distinctive appearance or products. Under Section 3 of the Thai Patent Act B.E. 2522, as amended by the Patent Act (No. 2) B.E. 2535 and the Patent Act (No. 3) B.E. 2542, a design is defined as “any form or composition of lines or colors that gives a product a special appearance and can serve as a pattern for an industrial or handicraft product.” This raises an important question. Can a patent be issued for a product design that contains text, numerals, trademarks, or symbols that do not fall under the definition of a design? This issue commonly arises when attempting to register packaging, labels, and graphical user interfaces (GUIs). Until a few years ago, applicants could file design applications with the Thai Patent Office for designs that contained such elements, provided that an appropriate disclaimer was included. This practice was generally accepted by Thai design examiners at that time, but the Patent Office has since implemented a change in its practice that could have a significant impact on applicants for design patents. Where design representations are submitted as line drawings or computer-aided design (CAD) drawings, the examiner may now issue an office action requiring their removal. This practice, however, appears to be applied inconsistently, as some examiners still exercise their own discretion in determining whether drawings containing these elements are acceptable. Below are examples of a GUI design, a CAD drawing design, and a photographic design representation that illustrates issues relating to the presence of nonallowable elements. GUI design For this GUI design, the submitted

Franchising in Thailand has matured into a sizeable commercial sector, but the rules governing franchisor–franchisee relationships remain scattered across general legislation rather than consolidated in a dedicated franchise statute. In this environment, the decisions of the Trade Competition Commission of Thailand (TCCT) have emerged as valuable practical guidance. Thailand follows a civil-law system in which judicial and administrative decisions do not create binding precedent; however, past rulings are nonetheless influential. This article examines the most instructive recent TCCT decisions and distills the practical compliance considerations for franchisors and franchisees operating in Thailand. Postcontract Changes: Justified or Unfair? A recurring issue is whether a franchisor may alter the terms of engagement after contract execution. The TCCT has established that midterm modifications are not inherently unfair; the determinative factors are whether there was a reasonable business justification, adequate advance notice, and a transparent process. In a 2023 coffee franchise matter, for instance, the TCCT declined to find a violation where a franchisor increased raw material prices, noting the increase had been communicated in advance and supported by demonstrable cost pressures. A bubble tea franchise matter reinforces this principle. The TCCT found that postcontract mandatory purchases of branded syrup and flavorings were justified, as the agreement reserved the franchisor’s right to modify product requirements, the materials were sold at or below market prices, and the branded ingredients possessed distinctive qualities deemed essential to franchise quality. The complaint was dismissed, with the additional requirements characterized as a legitimate measure to preserve brand consistency. Considered together, these decisions indicate that post‑contract modifications will be evaluated against three criteria: (1) whether there is a legitimate business rationale, (2) whether adequate advance notice was provided, and (3) whether franchisees were treated equitably throughout the transition.
