About the USPTO and the Office of Policy and International Affairs

Aside from the issuance of patents and registration of trademarks, the USPTO has a statutory mandate to advise the President and all federal agencies, through the Secretary of Commerce, on national and international IP policy issues, including IP protection in other countries. In addition, the USPTO is authorized by statute to provide guidance, conduct programs and studies, and interact with IP offices worldwide—and with international intergovernmental organizations—on matters involving IP.

The USPTO’s Office of Policy and International Affairs fulfills this mandate by leading negotiations on behalf of the United States at the World Intellectual Property Organization (WIPO); advising the Administration on the negotiation and implementation of the IP provisions of international trade agreements; advising the Secretary of Commerce and the Administration on a full range of IP policy matters, including in the areas of patent, copyright, trademarks, and trade secrets; conducting empirical research on IP; and providing educational programs on the protection, use, and enforcement of IP.
