Federal Circuit affirms PTAB invalidation of Uniloc patent which wasn’t invalid in 65 district court cases

The Uniloc patent invalidated by the PTAB in this case is U.S. Patent No. 5490216, titled System for Software Registration and issued in February 1996. It claims a registration system for licensing execution of digital data in a use mode, the system including both local and remote licensee unique ID generating means, and a mode switching means operable on a platform which permits the use of digital data only if the locally-generated licensee unique ID matches the remotely-generated licensee unique ID. The innovation solved issues in prior art systems for software registration for software transferable by physical media which used shell programs or did not utilize information unique to the intended licensee which is distinguishable from the identification of the platform. According to data collected from Lex Machina, Uniloc’s ‘216 patent has been asserted in 65 cases filed in U.S. district court going back to September 2003.
