Thai Intellectual Property, Trademark and Patent Practice

Thailand is a Madrid Protocol contracting party (since 2017) and a Patent Cooperation Treaty (PCT) member, making it a strategic Asian filing hub for brand and technology owners. iLC prosecutes trademarks, service marks, collective marks, certification marks, and geographical indications under the Trademark Act B.E. 2534 (as amended 2016), and patents / petty patents / designs under the Patent Act B.E. 2522. Enforcement is delivered through the Central Intellectual Property and International Trade Court (CIPITC), Customs recordal against counterfeit imports, e-Commerce takedown filings, and Suppression Division criminal complaints. Trademark examination timelines shortened to ~18 months in 2024, and DIP now offers e-filing with instant certificates upon grant.

End-to-End Process — ip trademark

The workflow below reflects current 2025–2026 practice with the relevant Thai authority and factors in queue seasonality, translation dependencies, and cross-agency handoffs.

  1. 1) Clearance search

    Availability search on DIP database, Madrid WIPO, and common-law usage to size opposition risk.

  2. 2) Classification and filing

    Nice classification (currently 11th edition, 45 classes) with claim drafting for optimal scope.

  3. 3) DIP examination

    Formalities check → substantive examination; office actions handled with argument or amendment.

  4. 4) Publication and opposition

    60-day opposition period; if unopposed, mark proceeds to registration.

  5. 5) Registration and certificate

    Digital certificate issued; 10-year term renewable indefinitely.

  6. 6) Enforcement and portfolio management

    Customs recordal, marketplace takedowns and annual watch reports.
