1. About สิทธิบัตPatent Law in Huai Khwang, Thailand

สิทธิบัตร law in Thailand is a national framework that protects new inventions, whether devices, processes, or chemical formulations. The protection lasts for a set period, typically twenty years from the filing date, subject to timely renewal and maintenance fees. In Huai Khwang, as in the rest of Bangkok and across Thailand, patent rights are administered by the Department of Intellectual Property within the Ministry of Commerce, not by a local Huai Khwang-specific court or agency. This means decisions and procedures are uniform nationwide.

The central requirements for patentability in Thailand include novelty, inventive steps, and industrial applicability. Applicants file with IP Thailand and may request substantive examination to assess patentability. After grant, patent owners must pay periodic maintenance fees to keep protection in force. Infringement cases are handled through Thailand’s civil courts, with patent disputes often pursued in Bangkok where courts and IP infrastructure are concentrated.

Patents in Thailand are granted for 20 years from the filing date, with annual maintenance fees required to keep the patent in force.
