Trademark Search & Clearance

A full search covers: (1) DIP Trademark Register — all registered and pending Thai marks, identical and similar; (2) WIPO Global Brand Database — international registrations designating Thailand; (3) ASEAN TMview — consolidated ASEAN trademark registers; (4) Thai-script phonetic analysis — transliteration of your mark into Thai and search for phonetically equivalent prior marks. For comprehensive searches, we add common-law use review. Each conflict is analysed across visual, phonetic, and conceptual similarity under the DIP Examination Guidelines and Section 13 of the Trademark Act B.E. 2534.

Standard search: 3–5 business days from receipt of the complete brief (mark, Nice class list, goods/services description). Comprehensive search including common-law use review, ASEAN TMview, and registrability strategy memo: 7–10 business days. Same-day expedited turnarounds are available on request. Quality should not be sacrificed for speed — a Thai-script phonetic conflict identified in day 3 saves a 14-month examination refusal.

A High Risk verdict means the search found one or more prior marks where the multi-factor Section 13 test weighs against you, and a DIP refusal is likely. You have three options: (1) modify the mark — add a design element, change a word component, or create more phonetic distance from the conflict; (2) negotiate co-existence with the prior owner if your goods/services are different enough; (3) proceed and argue through DIP examination — the most expensive and least predictable path. Narai Partners coordinates option 2 through the IR Global network when the prior owner is a foreign brand.

Yes — the DIP online search portal is publicly accessible and free. What you cannot do without professional trademark training: (a) construct phonetic-similarity searches across Thai script, (b) apply the multi-factor Section 13 likelihood-of-confusion test against DIP guidelines and Supreme Court precedent, (c) search the WIPO Global Brand Database and ASEAN TMview for cross-jurisdictional priority claims. The public DIP portal provides data; a professional search provides a registrability verdict. The analytical layer is where undetected conflicts hide.

No — and any provider claiming otherwise is misrepresenting the law. The DIP examiner exercises independent judgment, and any party may file an opposition during the 60-day publication window after a mark passes examination. A thorough search identifies the known obstacles before you spend the filing fee, so you make the application decision with complete information. Our clearance opinions are professional opinions, not guarantees — and we say so explicitly in every report.

We advise on the three options: modify the mark, negotiate co-existence, or proceed with risk-eyes-open. If modification is the right path, we work with you on the mark redesign and run a targeted re-search on the modified version before recommending filing. If co-existence negotiation is viable, Narai Partners handles the outreach — including cross-border coordination through IR Global when the prior owner is a foreign brand. If you decide to proceed despite the conflict, we file with a prosecution strategy designed for the anticipated office action.

Narai Partners (Plizz Group) is the IR Global member firm for Thailand. The difference is: (1) four-database coverage including Thai-script phonetic analysis — not available from most freelance agents; (2) partner-led written verdict with legal analysis, not a database printout; (3) cross-border coordination through IR Global when conflicts involve foreign marks or multi-jurisdiction filings; (4) integrated platform — trademark search is connected to company structure, accounting, and M&A advisory under one accountability chain.

The mark itself (word, logo, combined mark, or sound file for sound marks), the goods and services it will identify (specific enough to assign Nice classes), the geographic scope of intended use (Thailand-only, ASEAN, or wider), and whether the mark is already in use anywhere in the world. If you have prior foreign registrations or pending applications in other jurisdictions, share those — they affect the search strategy and any Paris Convention priority claim you may want to assert.
