Patent and Trademark Office
The United States Patent and Trademark Office (USPTO) was established by the act of July 19, 1952 (35 U.S.C. 1) "to promote the progress of science and the useful arts by securing for limited times to inventors the exclusive right to their respective discoveries for a certain period of time'' (Article I, Section 8 of the United States Constitution). The registration of trademarks is based on the commerce clause of the U.S. Constitution.
USPTO examines and issues patents. There are three major patent categories: utility patents, design patents, and plant patents. USPTO also issues statutory invention registrations and processes international patent applications.
Through the registration of trademarks, USPTO assists businesses in protecting their investments, promoting goods and services, and safeguarding consumers against confusion and deception in the marketplace. A trademark includes any distinctive word, name, symbol, device, or any combination thereof adopted and used or intended to be used by a manufacturer or merchant to identify his goods or services and distinguish them from those manufactured or sold by others. Trademarks are examined by the Office for compliance with various statutory requirements to prevent unfair competition and consumer deception.
In addition to the examination of patent and trademark applications, issuance of patents, and registration of trademarks, USPTO advises and assists government agencies and officials in matters involving all domestic and global aspects of intellectual property. USPTO also promotes an understanding of intellectual property protection.
This agency has published 1,052 documents since 1994.
