On August 19, 2016, Unified Patents Inc. filed its 50th inter partes review petition, against a patent owned and asserted by Intellectual Ventures I LLC.  The IPR2016-01643 challenges claims  1–4, 6–9, and 11–17 of U.S. Patent No. 6,775,745 B1, currently being asserted in the district court. This is the second patent from that assertion campaign that Unified has challenged to date. 

A copy of the petition can be found on our PTAB portal.
