Cisco Systems, Inc.vsLionra Technologies Limited

The PTAB found the claims unpatentable under 35 U.S.C. § 103 because they were obvious in light of prior art references (Cornett, Paatela, Nelson, Russell). The Board adopted a construction of 'concurrently writing' that aligned with both parties and district court precedent. Petitioner successfully demonstrated that the combination of disclosures taught all limitations of the claims for high-speed packet processing.
