Intellectual property work in Thailand splits into three registers with different rules. Trademark registration protects the brand name and logo, runs through the Department of Intellectual Property, and matters most because Thailand awards trademark rights to the first filer rather than the first user. Patent registration protects inventions and product designs, with terms from six to twenty years depending on the patent type. Copyright protection arises automatically when a work is created, so the legal work there is ownership paperwork, licensing, and enforcement rather than registration.
A trademark lawyer in Thailand typically starts a brand engagement with a register search, then handles filing, examination objections, and the sixty day opposition window through to the certificate. Patent work is drafting-heavy, and copyright work is contract-heavy. Many firms on this page cover all three; others concentrate on one register, which is worth checking against what your business actually needs protected.

Experts assisting clients in conducting their businesses and protecting their rights and investments in Thailand across a wide range of legal matters.
Enforcement in Thailand runs through the Central Intellectual Property and International Trade Court, and the Trademark, Patent, and Copyright Acts all carry criminal penalties for infringement alongside civil claims. Thailand is also plugged into the international system: the Madrid Protocol for trademarks since 2017, the Patent Cooperation Treaty since 2009, and the Berne Convention for copyright since 1931, so international filings can designate or enter Thailand through a local firm.
What a firm quotes is worth reading in two parts. Official fees are set by law or regulation, such as the trademark application fee of 1,000 baht per item of goods for up to five items in a class. Professional fees for searching, drafting, and prosecution are set by each firm and vary with the complexity of the mark or invention, so comparing firms means comparing what each engagement includes. This page is general information, not legal advice; for a specific brand, invention, or dispute, speak with a qualified professional.
