BT Americas, Inc. v. Palo Alto Networks, Inc.

BT Americas, Inc. v. Palo Alto Networks, Inc. The Federal Circuit affirmed the Board's final written decision in IPR2023-00889 holding claims 1-25 of the '641 patent unpatentable as obvious. Substantial evidence supported the Board's findings on dynamic modification, motivation to combine, and claim 6's SOC analysis, and the court rejected the argument that the Board lacked jurisdiction over an expired patent. The decision shows the deference given to Board fact-finding crediting expert testimony on obviousness, and it confirms that expiration of a patent before the petition was filed does not deprive the Board of IPR jurisdiction under Gesture Technology. Affirmed. BTA appealed the Board's final written decision that claims 1-25 of the '641 patent (dynamic network intrusion monitoring) were unpatentable under § 103. The Board found claims 1-7 and 15-17 obvious over Duvall and Chu and relied on other grounds for the remaining claims, which BTA did not challenge on appeal. Dynamic modification: substantial evidence supported the Board's finding that Duvall's dynamically modifiable filter database changes the probe's analysis capability during operation. The Board credited expert testimony that this was a routine database feature, and the Duvall-Chu system did not need significant alteration. The court also rejected BTA's cached-copy argument because Duvall does not require a cached copy. Claim 6: BTA misread the petition. PAN relied on two analyst systems, one at the SOC that takes part in the multi-stage analysis and one at the probe, so the Board did identify the claimed analysis at a SOC. The court also found substantial evidence for the motivation-to-combine findings. Jurisdiction: the argument that the Board lacked jurisdiction over a patent expired before the petition was filed was foreclosed by Apple Inc. v. Gesture Technology Partners, 127 F.4th 364, which the panel could not depart from and saw no persuasive reason to doubt. § 103 claim construction standing / jurisdiction non-precedential § 103 standing / jurisdiction non-precedential § 103 standing / jurisdiction
