PHOTOMOSAIC PATENT CHALLENGED BY PUBPAT: U.S.P.T.O. Asked to Review and Revoke Patent Asserted Against Important Open Source Project

New York, NY -- September 9, 2008 -- The Public Patent Foundation ("PUBPAT") announced today that it has filed a formal request with the United States Patent and Trademark Office to review a patent relating to photomosaics, which are large pictures made by using many smaller pictures. 

The patentee, Mr. Robert Silvers, has been aggressively asserting the patent against many individuals, small businesses, and even against an important open source software program (GIMP)

In its filing, PUBPAT submitted prior art that the Patent Office was not aware of when reviewing the application that led to the issuance of the patent (U.S. Patent No. 6,137,498), described in detail how the prior art invalidates the vast majority of the claims of the patent and asked that those claims of the patent be revoked.
