Detailed Summary

In Request for Director Review IPR2024‑00677, Cisco Systems, Inc. and Fortinet, Inc. challenge the PTAB’s Final Written Decision concerning U.S. Patent No. 8,578,444, which covers authentication using EAP protocols over 802.1x networks. The petition alleges that the patent owner, InfoExpress Inc., violated 37 C.F.R. § 42.6(a)(3) by incorporating extensive conception and diligence arguments by reference rather than presenting them directly in the Response, thereby depriving the Board of a proper factual record. Citing Federal Circuit precedent on the importance of detailed disclosure, the petitioners argue that the Board’s reliance on such improperly incorporated material constitutes an abuse of discretion. They request that the Director vacate the decision and remand the case for a proper merits analysis.
