Detailed Summary
In Request for Director Review IPR2024-00678, Cisco Systems, Inc. and Fortinet, Inc. challenge the PTAB’s Preliminary Decision that denied institution of an inter partes review of U.S. Patent No. 8,117,645, which claims a method for formulating an audit request in a security policy audit. Petitioners argue the Board erred by restricting the Krantz prior‑art reference to user authentication, ignoring disclosures of device information, operating‑system credentials, and encryption protocols that fall within the “audit request” limitation. They cite dependent claims of the related ’350 continuation patent to support a broader reading and request the Director vacate the decision and institute the IPR. The petition includes expert testimony from Dr. Henry Houh and references the Krantz reference as prior art.
