Executive Summary
The PTAB found claims unpatentable under 35 U.S.C. § 103(a) based on a combination of prior art references (Gai, Yip, Kwan, and Georgiou). The Board determined that an ordinary skilled artisan would have been motivated to combine these teachings to enhance network security and implement advanced ACL functions.
