An intellectual property lawyer in Bangkok can do three quite different jobs: register rights, advise on how they are owned and used, and enforce them when someone copies. Most firms listed here are full-service practices where IP sits beside corporate, property and dispute work, and at least one is a dedicated IP firm. Both models can suit a client. What matters is whether the firm lists the specific work you need.
The profiles are not interchangeable. Copyright and licensing appear on most of them, trademark filing on fewer, and patent work and IP disputes on fewer still. One firm lists the practice area without naming individual services, so ask it directly. Open each profile to see the services a firm reports before you contact it.
Each card shows the languages a firm works in and whether the first consultation is free or paid, where the firm has listed it. Every firm here works in English and Thai, and several add Chinese, German, French or Japanese, which matters if your brand or invention documents are in one of those languages. For how trademarks, patents and copyright are protected across the country, see the Thailand-wide guide to IP protection.
Registration is filing work with the Department of Intellectual Property. For a brand, that means search, filing and replies to the registrar; the Bangkok trademark registration page covers the documents and deadlines. For an invention, it means drafting claims and prosecuting the application; see patent lawyers in Bangkok. Copyright needs no registration, but an owner can file a voluntary notification with the Department, and the DIP's notification procedure lets an attorney-in-fact file it on the owner's behalf.
Advisory work is mostly contracts. It covers who owns what a team or contractor creates, licensing agreements that let others use a brand or technology, and the confidentiality measures behind trade secret protection. It is often where a business needs IP help first, before any filing.
Enforcement starts when a right is copied: evidence, a demand letter, negotiation and, if needed, a case. Check that a firm's profile lists IP disputes before you contact it about a case. Ask whether the same team that handles your filings would also appear in court.

Blumenthal Richter Sumet & Schuler is a leading law firm in Bangkok, Thailand. We provide legal services in all practice areas.
Experts assisting clients in conducting their businesses and protecting their rights and investments in Thailand across a wide range of legal matters.
Three offices do most of the work. The Department of Intellectual Property sits just outside the city in Nonthaburi, and filings reach it electronically or through an agent, so few clients ever visit.
Disputes go to the Central Intellectual Property and International Trade Court on Chaeng Watthana Road in Lak Si. Its published jurisdiction covers civil and criminal trademark, copyright and patent cases, disputes over technology transfer and licensing agreements, and trade secret cases. Because no regional IP courts have been set up, it currently hears these cases from across the country.
The third office is the Customs Department's IPR Coordination Center in Khlong Toei. Trademark and copyright owners can record their rights in the Customs trademark and copyright database, known as TCIRs, to request Customs protection for those rights. If copies of your products are being imported, ask whether a firm handles Customs recordation as part of its enforcement work.
