This ruling removes a multi-year patent overhang that had potential for multi-billion-dollar liability and reputational risk. CSCO shares should benefit from the clarity; monitor for any SCOTUS cert petition, though unlikely given the failure of Centripetal's arguments on appeal.

Executive Summary
The Federal Circuit affirmed Cisco's victory in a long-running patent dispute with Centripetal Networks, holding that Cisco's products do not infringe three asserted patents related to network packet filtering. This final appellate ruling eliminates a significant litigation overhang and potential liability that had previously resulted in a vacated $1.9B+ verdict.
Court Ruling Details
Key Facts
- Federal Circuit affirmed district court's judgment of noninfringement on all three asserted patents ('193, '806, '176).
- The patents relate to packet filtering for network security threats; Cisco's products were found to lack the claimed two-stage filtering, but-for causation, and auto-correlation features.
- Original 2020 verdict of willful infringement (over $1.9B) was vacated in 2022 due to judge recusal; this decision conclusively resolves the case in Cisco's favor.
- Costs awarded to Cisco.
Financial Impact
Avoided potential damages that could have exceeded $1.9B plus ongoing royalty risk; no financial impact from this ruling as no damages awarded.
Risk Factors
- Centripetal could seek en banc rehearing or petition for certiorari to the Supreme Court, but chances of reversal are low.
- Remaining '856 patent still pending in district court, though not asserted in this appeal.
