Patent Filing and Registration in Bhutan

Patents in Bhutan play a critical role in protecting inventions and encouraging innovation in an emerging industrial and technology-driven market. Governed by the Bhutan Intellectual Property Act and managed by the Ministry of Economic Affairs (Department of Intellectual Property), the system ensures inventors receive exclusive rights to manufacture, use, or sell their innovations within Bhutan.

Understanding Bhutan’s patent framework is essential for local and international innovators, especially for those considering international patent filing for global protection.

Bhutan’s Patent System Overview

Bhutan follows a first-to-file system, granting patents to the first valid applicant rather than the actual inventor. This approach encourages early filing and careful preparation of applications.

Patent protection in Bhutan generally covers:-

Technical inventions (products or processes)
Utility models (practical innovations)
Industrial designs (appearance and aesthetics of products)

Foreign applicants can file patents but must appoint a registered Bhutanese patent agent or attorney to comply with local legal requirements.
