USPTO Releases Annual List of Top 10 Organizations Receiving Most Patents

PRESS RELEASE


IBM repeats at top of list

The United States Patent and Trademark Office (USPTO) announced the top 10 private sector patent recipients for the 2001 calendar year. Listed below are the 10 corporations receiving the most patents for inventions in 2001, along with their ranking last year. For the ninth consecutive year, IBM received more patents than any other private sector organization.

"I am proud that American corporations are leaders among U.S. patent holders," said James E. Rogan, Under Secretary of Commerce for Intellectual Property. "Patents promote technological progress and are a potent force for competitive free enterprise. Global confidence in the U.S. patent system confirms the strength of the American marketplace, and plays a key role in bringing an end to the recession."
