Federal Circuit Remands Based On Inadequate Explanation, PTAB Litigation Blog

Palo Alto Networks (PAN) filed a petition for inter partes review of Centripetal Networks’ patent—U.S. Patent No. 10,530,903—which is directed to a computing system for correlating packets in communication networks with a network device and multiple hosts. The PTAB upheld the patent claims, finding that PAN had not shown that the prior art taught or suggested transmitting an indication of the first host (the source of malicious activity) responsive to the correlation of packets across network boundaries. PAN appealed. The Federal Circuit vacated and remanded the PTAB’s decision because the PTAB (1) failed to make clear findings on motivation to combine references; and (2) improperly analyzed the prior art references in isolation rather than as a combined whole.
