The 3-Year Non-Use Cancellation Trap: A Shorter Window Than You Might Expect

Brand owners accustomed to the five-year non-use periods common in the European Union, United Kingdom, Australia, and many other Western jurisdictions often enter Thailand without appreciating a critical difference: Thailand’s non-use cancellation period is just three years. Under Section 63 of the Thai Trademark Act B.E. 2534 (1991), a registered trade mark that has not been used in bona fide commerce for three consecutive years is vulnerable to cancellation. This shorter timeline creates a tighter obligation on registrants and a more aggressive tool for challengers — but the practical dynamics of the Thai cancellation system add significant complexity.

The Legal Framework: Section 63

Section 63 of the Thai Trademark Act provides that any interested person or the Registrar may petition the Board of Trademarks to cancel a trade mark registration on one of two grounds:

• No bona fide intent at registration: At the time of registration, the owner had no genuine intention to use the mark for the registered goods, and in fact there has been no bona fide use whatsoever of the mark for those goods.
• Non-use in the preceding three years: During the three years immediately prior to the filing of the cancellation petition, there has been no bona fide use of the mark for the registered goods.

The owner can defend the registration by proving that the non-use was due to “special circumstances in the trade” and was not the result of an intention not to use or to abandon the mark.

Three Years vs. Five Years: Why This Matters

The three-year non-use period is significantly shorter than the five-year period applied in the EU, UK, Australia, China, Japan, and most other major trade mark jurisdictions. For international brand owners managing global portfolios, this creates several risks:

• Faster vulnerability: A registration becomes susceptible to cancellation just three years after registration (or after the last bona fide use), leaving less time for brands to enter the Thai market or establish local distribution.
• Portfolio management gaps: Companies that monitor their portfolios based on a five-year non-use assumption may not flag Thailand registrations until after the three-year window has passed.
• Defensive registrations at higher risk: Registrations filed to reserve a position in Thailand without immediate commercial plans are exposed earlier than in other jurisdictions.

The Burden of Proof: A Double-Edged Sword

One of the most significant features of the Thai non-use cancellation system is the allocation of the burden of proof. Unlike jurisdictions such as the UK or EU where the burden shifts to the registrant upon a prima facie showing of non-use, Thailand places the initial burden squarely on the petitioner. The petitioner must prove both that they are an interested person and that the mark has not been used in bona fide commerce.

This creates a practical paradox: the petitioner must prove a negative fact — that the mark has not been used. Proving that something did not happen is inherently difficult, particularly when the petitioner has no access to the registrant’s business records. In practice, petitioners rely on market investigation reports, searches of Thai retail and online channels, inquiries with industry participants, and regulatory checks (such as confirming the absence of import licences or product registrations).

The Conservative Board of Trademarks

Historically, the Thai Board of Trademarks has been conservative in granting non-use cancellations. In many cases, the Board accepted the registrant’s assertion of an “intention to use” the mark as sufficient to defeat a cancellation petition, even without concrete evidence of actual commercial use. Investigation reports showing no evidence of use were sometimes deemed insufficient, and the Board has been reluctant to cancel registrations even where the registrant defaulted on filing a response.

This conservative trend has been a source of frustration for petitioners and brand owners seeking to clear blocking marks from the register.

A Landmark Shift: The 2021–2022 Court Decisions

A significant development occurred in 2021–2022 when the CIPIT Court and the Court of Appeal for Specialised Cases issued landmark decisions that reversed the Board’s conservative approach. In a notable case, the CIPIT Court ruled that a registrant who had held a mark since 2009 but never used it could not defeat a non-use cancellation by merely claiming a “marketing plan” without providing concrete evidence of use or genuine preparation for use.

The Court clarified that “special circumstances in the trade” — the statutory defence to non-use — refers to conditions affecting overall business activities in the country, such as government import restrictions or regulatory prohibitions, and does not include the registrant’s personal business decisions like delays in marketing or manufacturing plans. This interpretation significantly narrowed the scope of the defence and raised the bar for registrants seeking to maintain unused marks.

The Court of Appeal affirmed this decision in October 2022, establishing a stronger precedent that trade mark registrants must demonstrate actual use or genuine preparation for use, not merely an abstract intention.

The “Interested Person” Requirement

A persistent challenge in Thai non-use cancellation is the requirement that the petitioner be an “interested person.” The Thai Trademark Act does not define this term, and the Board of Trademarks and courts have interpreted it inconsistently. Some decisions have narrowed the definition to parties whose own trade mark applications have been refused due to the cited mark, while others have adopted a broader standard encompassing anyone with a “connecting point” to the registered mark.

This uncertainty means that petitioners should be prepared to demonstrate their legitimate interest — ideally by holding a pending application that has been cited against the registered mark, or by showing a concrete commercial interest affected by the registration.

No Partial Cancellation

An important limitation of the Thai system is that partial cancellation is not available. The petitioner must prove non-use across all of the registered goods, not just a subset. If the registrant can demonstrate bona fide use for even some of the registered goods, the entire registration may survive. This makes non-use cancellation more difficult in Thailand than in jurisdictions that permit partial revocation for unused goods.

Strategic Recommendations

• Use your mark within three years: Begin genuine commercial use in Thailand within three years of registration. Do not assume you have five years, as in other jurisdictions.
• Maintain evidence of use: Systematically collect and preserve evidence of use in Thailand — sales invoices, product photographs, distribution records, advertising materials, and import documentation.
• Monitor your Thai portfolio on a three-year cycle: Adjust portfolio management systems to flag Thai registrations approaching three years without use.
• For challengers, build a comprehensive evidence package: Invest in market investigation reports, regulatory database checks, and industry inquiries to demonstrate the absence of use. Single investigation reports alone may be insufficient.
• Demonstrate standing clearly: Petitioners should establish their “interested person” status through a pending application or concrete commercial interest linked to the registered mark.

Common Mistakes

• Assuming a five-year grace period: This is the most dangerous error for international portfolio managers. Thailand’s window is three years, not five.
• Relying on “intention to use” as a defence: Following the 2021–2022 court decisions, a bare intention to use, without concrete evidence, is no longer a reliable defence.
• Filing cancellation without proving standing: Petitioners who cannot demonstrate they are “interested persons” risk having their petitions rejected on procedural grounds.
• Expecting partial cancellation: Thailand does not allow partial cancellation. The non-use must be proven for all registered goods.

Key Takeaway

Thailand’s three-year non-use cancellation period under Section 63 creates a tighter use obligation than most Western jurisdictions. While the burden of proof on petitioners and the Board’s historically conservative approach have made cancellations difficult to achieve, recent court decisions have raised the standard for registrants and narrowed the “special circumstances” defence. For brand owners, the message is clear: use your Thai registrations within three years, maintain evidence, and do not assume the five-year timeline that applies elsewhere. For challengers, the landscape is improving, but a well-documented evidence package and clear demonstration of standing remain essential.
