U.S. Patent Office and Trademark Office

The United States Patent and Trademark Office (USPTO) is the Federal agency for granting U.S. patents and registering trademarks. In doing this, the USPTO fulfills the mandate of Article I, Section 8, Clause 8, of the Constitution that the Executive branch "promote the progress of science and the useful arts by securing for limited times to inventors the exclusive right to their respective discoveries." The USPTO registers trademarks based on the Commerce Clause of the Constitution (Article 1, Section 8, Clause 3). Under this system of protection, American industry has flourished. New products have been invented, new uses for old ones discovered, and employment opportunities created for millions of Americans. The strength and vitality of the U.S. economy depends directly on effective mechanisms that protect new ideas and investments in innovation and creativity. The continued demand for patents and trademarks underscores the ingenuity of American inventors and entrepreneurs.
