Short Summary
Cisco Systems challenges Lionra Technologies' patent (7623518) in an IPR, asserting that multiple claims are obvious over combinations of prior art. The petitioner focuses on network access control list (ACL) improvements and dynamic packet handling techniques using references like Gai, Yip, Kwan, and Georgiou.
Detailed Summary
Cisco Systems, Inc., the petitioner, has filed a Petition challenging eight claims of Lionra Technologies Limited's patent No. 7623518 before the PTAB. The core argument is that these claims are obvious under 35 U.S.C. § 103. Cisco presents several grounds, including combining Gai with Yip and Kwan to show obviousness for Claims 1 and 3 (related to enhanced ACLs), and combining Gai, Kwan, and Georgiou to challenge Claims 15, 17, 19-21 (related to dynamic packet storage and processing). The petitioner details how the combination of these references yields predictable results in computer networking, particularly concerning access control list functionality and handling specific network packets.
