PTAB Cancels Asserted Claims in AIP Voice Communications Patent

  • May 27, 2016

A voice communications patent (7,269,247) asserted by NPE AIP Acquisition LLC has been partly invalidated by the Patent Trial and Appeal Board (PTAB). In an inter partes review (IPR) initiated by Cisco (IPR2015-00307), the Board issued a final decision on May 18, 2016, ruling that claims 1-9, 11-24, and 26-29 of the ‘247 patent—including all of those asserted in litigation—are obvious in light of prior art. The ‘279 patent is the fifth asserted in this campaign (6,078,654; 6,188,756; 6,496,579; 7,724,879) to see claims cancelled via IPR.
