Bangkok · Thailand · Intellectual Property Law
Thailand's intellectual property framework protects the work of creators, inventors, and brands — but only when the right steps are taken at the right time. Pranakorn advises on trademark registration, patent filing, copyright protection, and trade secrets with the patience that careful IP practice requires.
Request a ConsultationPractice Areas
Each engagement is approached with attention to the type of IP at stake, the registration pathways available under Thai law, and the enforcement or protection options that best suit the client's commercial position.
Comprehensive guidance through the trademark registration process under the Thai Trademark Act B.E. 2534 — from clearance search and class selection through to filing, examination, and registration. We also advise on the Madrid System for international coverage.
Advisory support for invention and petty patent applications under the Thai Patent Act B.E. 2522 — covering patentability assessment, specification drafting guidance, filing strategy, and the examination process before the Department of Intellectual Property.
Practical advisory on copyright protection under the Thai Copyright Act B.E. 2537 and trade secret protection under the Trade Secrets Act B.E. 2545 — including ownership structure, licensing frameworks, infringement assessment, and the contractual measures that protect confidential business information.
Why Pranakorn
We follow the practice of Thailand's Department of Intellectual Property closely, including examination guidelines, classification updates, and enforcement protocols — so advice reflects current DIP practice, not outdated procedure.
IP rights are often time-sensitive. Our approach prioritizes filing strategy that protects priority dates and prevents third parties from registering ahead of you — because a delayed application can cost more than the registration itself.
Each engagement produces written output — an assessment, a filing strategy note, a compliance memo — in language that founders, product teams, and commercial directors can read and act on without a legal interpreter.
Many assets attract protection under multiple IP regimes simultaneously. A product design may involve both patent and copyright; a brand may involve both trademark and trade secret. We are familiar with these overlaps and advise on the most appropriate combination of protections.
Our practice works with the people building and running businesses in Thailand — startups, product companies, international brands entering the Thai market — with an understanding of how IP fits into commercial strategy rather than existing in isolation from it.
Where registration alone is insufficient — because a mark is weak, a patent claim is narrow, or an infringement case is uncertain — we say so, and advise on the approaches that build the strongest position over time rather than the fastest path to a certificate.
Before You Proceed
If you are building a brand, developing an invention, or bringing original work to market in Thailand, a short initial discussion can clarify which protections apply and what steps are worth taking first.
