Patents and Trademarks: United States

Information on finding patents and US trademarks

US Patent and Trademark Office

The United States Patent and Trademark Office (USPTO) is repsonsible for registering and maintaining all patent and trademark records in the United States. Usually to file a patent on USC research, you will go through the USC Stevens Center for Innovation, not directly through USPTO.

USPTO does maintain searchable databases of all US patents.

Google Patents

Google Patents coverage includes:

  • United States (1790-present)
  • European Patent Office, EPO (1981-present)
  • World Intellectual Property Organization, WIPO (some coverage)
  • Some Germany, China, and Canada patents

If you are having issues searching the USPTO databases, try searching Google Patents to find the US patent number. Then go back to the USPTO and search by patent number.
