1. About สิทธิบัตร Law in Bangkok, Thailand

In Bangkok, as the capital and commercial hub of Thailand, patent law is administered by the Department of Intellectual Property (DIP) under the Ministry of Commerce. This framework governs the filing, examination, grant, and enforcement of patents within Thailand's borders. Filing or prosecuting a patent application typically involves Bangkok-based offices and courts, including the Intellectual Property Court for disputes.

Thai patent law protects new inventions that meet the criteria of novelty, inventive step, and industrial applicability. The law also provides avenues for maintenance, licensing, assignment, and enforcement against infringement. Practitioners in Bangkok help navigate translations, filing strategies, and local procedural requirements to secure patent rights in Thailand.

For residents and businesses in Bangkok, understanding local procedures is essential because patent rights are territorial and limited to Thailand unless extended via international routes.
