Case Study: Foreign Business Owner Recovers Stolen Brand Trademark
How a foreign restaurant chain owner in Bangkok recovered their brand name after a Thai ex-partner registered it as a trademark. Learn about DIP opposition proceedings and IP court action in Thailand.
This case study is based on anonymized real-world situations and is presented for educational purposes only. Specific outcomes depend on individual circumstances, the jurisdiction, and judicial discretion.
The Situation
A Japanese national had been operating a successful chain of three ramen restaurants in Bangkok under a distinctive brand name for five years. After a business dispute, his former Thai partner — who had managed the local company — secretly filed a trademark application with the Department of Intellectual Property (DIP) for the restaurant's brand name and logo. The foreign owner discovered this when he attempted to register the trademark himself and found it was already registered in his ex-partner's name. The ex-partner then demanded THB 2 million to transfer the trademark back, threatening to open competing restaurants under the same brand.
Legal Issues Involved
Bad-faith trademark registration by former business partner (Trademark Act B.E. 2534 (1991), Section 67)
Prior use rights and evidence of brand ownership before registration
Trademark opposition and cancellation proceedings at the DIP
Unfair competition and passing off under Thai civil law
Recovery of damages for unauthorized use of the brand
What Happened (Process)
- 1
Gathered evidence of prior use: business registration, marketing materials, receipts, and social media presence dating back five years
- 2
Filed trademark opposition at the DIP Trademark Registrar within the 90-day opposition window
- 3
Simultaneously filed a civil lawsuit at the Central Intellectual Property and International Trade Court (IP&IT Court)
- 4
Court issued a preliminary injunction preventing the ex-partner from using the brand during proceedings
- 5
DIP Board ruled that the registration was filed in bad faith given clear evidence of prior use
- 6
IP&IT Court heard the full case over two hearings spanning four months
- 7
Court cancelled the ex-partner's trademark registration and ordered transfer to the rightful owner
- 8
Damages of THB 500,000 awarded for lost business and legal costs
Outcome
The trademark was cancelled and re-registered in the foreign owner's name. The IP&IT Court awarded THB 500,000 in damages covering lost revenue during the dispute period and legal expenses. The ex-partner was permanently enjoined from using the brand. The entire process took approximately 8 months from initial opposition filing to final court order.
Key Lessons
Always register your trademark in Thailand as early as possible — prior use alone does not guarantee protection without registration.
Keep detailed records of brand usage: dated photographs, receipts, marketing materials, and business registration documents.
The 90-day opposition window after trademark publication is critical — monitor the DIP Gazette regularly.
Bad-faith registration by former partners or employees is a recognized ground for cancellation under Thai law.
The IP&IT Court is a specialized court that handles these cases efficiently compared to general courts.
