Best Patent Lawyers in Bang Khun Thian

About Patent Law in Bang Khun Thian, Thailand

Bang Khun Thian is a district in Bangkok, and patent matters here are governed by Thailand’s national Patent Act and handled centrally by the Department of Intellectual Property under the Ministry of Commerce. If you live, work, or run a business in Bang Khun Thian, your patent filings, enforcement, and licensing are subject to Thai law and are typically processed in Bangkok. Thailand recognizes three main forms of protection: patents for invention, petty patents, and design patents.

- Patent for invention: protects technical solutions and processes that are new, involve an inventive step, and are industrially applicable. Usual term is 20 years from filing, subject to annual maintenance fees.

- Petty patent: similar to a utility model. Protects incremental inventions that are new and industrially applicable, but inventive step requirements are lower. Usual term is 6 years with possible extensions up to 10 years total.

- Design patent: protects the ornamental appearance of a product. Usual term is 10 years from filing.

Patent rights allow the owner to prevent others from making, using, selling, offering for sale, or importing the protected invention in Thailand. Because Bang Khun Thian hosts a mix of manufacturing, logistics, and food processing businesses, patents can be particularly important for equipment, processes, packaging, and product designs used locally and nationwide.
