Short Summary
The PTAB denied institution of IPR for Cisco and Fortinet against InfoExpress, finding no reasonable likelihood that the challenged claims of U.S. Patent No. 8,347,350 would be found obvious over prior art.
Detailed Summary
Cisco Systems, Inc. and Fortinet, Inc. petitioned for Inter Partes Review (IPR) against InfoExpress Inc.'s patent 8,347,350, asserting obviousness over Krantz and Herrmann. The Board denied institution of the IPR because Petitioner failed to establish a reasonable likelihood of prevailing on any challenged claim. Specifically, the Board rejected arguments that user authentication in the patented invention constituted applying a security policy, noting that the '350 patent describes these as separate process steps.
