Protecting Trade Secrets Essential to Stay Ahead

Bangkok Post, Corporate Counsellor Column

Intellectual property rights (IPR) protection is a key part of success in today’s business environment. As manufacturing companies grow, it is inevitable for corporate management—regardless of the type of industry—to shift its focus from tangible products to the intangible assets of intellectual property.

While trademarks, copyrights, and patents are a central focus in discussions of IPR among business owners, there is another important intellectual property right that can improve a company’s competitive advantage and help it differentiate its business and/or products from those of its competitors: the “trade secret.”

Trade secrets are protected in Thailand under the Trade Secret Act (TSA) B.E. 2545 (2002). The principal rule of a trade secret is that it can be protected as long as it is undisclosed.

Section 3 of the TSA states: “Trade secrets mean 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 the trade secrets has taken appropriate measures to maintain the secrecy.”

“Trade information means any medium that conveys the meaning of a statement, facts, or other information irrespective of its method and forms. It shall also include formulas, patterns, compilations or assembled works, programs, methods, techniques, or processes.”

Trade secrets can be categorized into two types:

  • Industrial secrets, which consist of trade information related to technical matters such as a manufacturing process or a chemical formula.
  • Commercial secrets, which consist of trade information related to sales methods, contract forms, customer lists, advertisement techniques, etc.

Unlike patent protection, there is no expiration date for trade secret protection and no registration procedure is required to obtain trade secret protection. Instead, trade secrets shall be protected as long as they are deemed secret. As the length of time for trade secret protection can be short or long, depending on the ability of the company to maintain the secrecy of its valuable information, it is therefore very important for the company to understand how to maintain and manage its information.

In recognition of this need, the Trade Secret Act stipulates that the controller of a trade secret take “appropriate measures” to maintain the secret. “Appropriate measures” can vary, depending on the type of information. It is recommended, however, that the company should, at the very least, implement a “confidentiality policy” among its employees, especially for those whose work relates to technical information, production, research and development, as well as sales and marketing.

A “non-disclosure term” should be standard in the company’s employment agreements. Also, special steps should be taken to ensure that employees have proper authorization to access any of the company’s important information. These steps should include such measures as passwords, fingerprint scans, and iris scans, among any other method for identification.

Under the law, the trade secret owner has the right to disclose, take, or use his trade secret, and/or permit others to use his right along with any necessary condition to maintain its secrecy. Acts amounting to infringement of a trade secret right under the TSA include disclosure, deprivation, or use of a trade secret without the consent of the owner in a manner contrary to honest trade practices. In so doing, the infringer must be aware or has reasonable cause to be aware that such act is contrary to honest trade practices.

Where there is clear evidence that a trade secret infringement has been committed or is imminent, the affected controller is entitled to apply to the Intellectual Property and International Trade Court (IP&IT Court) for the following injunctions:

  • A preliminary injunction ordering the violator to temporarily stop or refrain from infringing the trade secret, whether before or after the filing of a suit with the Court; and
  • A permanent injunction prohibiting the violator from infringing the trade secret. In addition to damages for the actual damage suffered, in trade secret litigation the court may include in the damages for the plaintiff an accounting of profits accrued from or in connection with the infringement by the infringer.

The greatest advantage of trade secret protection is that a company can maintain secrecy and know-how. Also, there is no time limitation for protection as long as the secrets are deemed secret. Therefore, if a company decides to obtain protection for its know-how through the TSA, it must ensure that it can manage and protect its secret through company capital and/or human effort.

As to whether protection is obtained through a patent or trade secret, it is recommended that a company should weigh the value of the know-how against its ability and capital to manage and maintain the secret. If it is valuable, trade secret protection may be worthwhile for the company to maintain long-term protection.

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.

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.
