Intellectual property, in outline

Thailand protects trademarks, copyright, patents and related rights through its own registration system, administered mainly by the Department of Intellectual Property, with disputes heard in a dedicated Central Intellectual Property and International Trade Court.

Trademarks

• Registering a company name at the Department of Business Development does not give you trademark rights — trademark protection requires a separate application to the Department of Intellectual Property.
• Thailand generally follows a first-to-file system for trademarks, meaning the first party to register a mark generally wins the right to it in Thailand — using a name or logo first, without registering, offers weaker and less certain protection.
• Registration is by class of goods or services; a mark registered for one type of business does not automatically block use in an unrelated field.
• Thailand is a member of the Madrid System, which lets an existing trademark registration in a home country be extended into Thailand through a single international application in many cases.

Copyright

Copyright in Thailand arises automatically on creation of an original work — writing, photography, software, music, art — without needing registration, broadly consistent with international copyright norms. Formal recording with the Department of Intellectual Property is available and can help as evidence of ownership and creation date if a dispute arises, but is not what creates the right itself. Using someone else’s copyrighted material — including images and text lifted from other websites — without permission or a valid licence is an infringement regardless of whether the original was registered.

Patents and designs

Patent protection for inventions, and separate registration for product designs, both require a formal application and examination process before the Department of Intellectual Property, and neither arises automatically the way copyright does. Patent applications take considerable time to examine, and an invention publicly disclosed before filing can lose its eligibility for protection — timing the application before any public disclosure matters a great deal.

Trade secrets and know-how

Thailand’s Trade Secrets Act protects confidential business information — formulas, processes, customer lists — that derives value from not being generally known and that the owner has taken reasonable steps to keep secret. Unlike trademarks and patents, this protection does not depend on registration, but it does depend on being able to show the information was genuinely kept confidential; a business that never uses non-disclosure agreements or access controls has a much weaker position if information leaks.

Enforcement

Infringement can be pursued civilly for damages and injunctions, and certain infringement — particularly counterfeiting and large-scale piracy — also carries criminal penalties, with specialised investigators and the Central Intellectual Property and International Trade Court handling these cases; see how the Thai legal system works. Customs recordal is also available, letting rights holders ask Customs to intercept counterfeit goods at the border.

For small businesses and freelancers

The most common IP mistakes are avoidable ones: launching a brand without checking whether the name is already registered by someone else, assuming a company registration protects a brand name it does not, and using freelance-commissioned content or code without a written agreement that actually assigns ownership to the business rather than leaving it with the freelancer by default. Getting these basics right at the start is dramatically cheaper than untangling them after a dispute — see business & foreign ownership and contracts & disputes.
