Patent

A product, a process, or an improvement of either, when the invention is new, not obvious to a person skilled in that field, and capable of industrial application. Discoveries, scientific theories, and business methods as such are not patentable inventions.

Twenty years from the Thai filing date. The term is not renewable. Annual fees are required to keep the patent in force.

The applicant’s name and address, the inventors, a description of the invention, the claims that define the protection, and drawings where the invention needs them. A filing made abroad may support a later Thai application if the priority deadline is still open.
