Actionable Insight ▲ Bullish

Keysight's victory in invalidating all challenged claims reduces near-term litigation risk and removes uncertainty around potential licensing or damages. Traders should view this as a positive resolution to a material legal overhang, particularly given the company's focus on network security technologies covered by the patent.

Executive Summary

The U.S. Court of Appeals for the Federal Circuit affirmed that Keysight Technologies does not infringe claims 1–3, 5–13, and 15–20 of Centripetal Networks' patent, but reversed the lower board's decision on claims 4 and 14, ruling they are invalid due to obviousness. This strengthens Keysight's position in the ongoing patent dispute by invalidating key claims.

Key Facts

  • Court of Appeals for the Federal Circuit ruled on appeal in Centripetal Networks, LLC v. Keysight Technologies, Inc.
  • Affirmed unpatentability of claims 1–3, 5–13, and 15–20 of U.S. Patent No. 10,193,917 for obviousness.
  • Reversed the Patent Trial and Appeal Board’s finding that claims 4 and 14 were not obvious, holding they are invalid.
  • The decision was issued on April 23, 2026, and is nonprecedential.
  • Keysight had challenged the validity of the patent via inter partes review, which led to this appellate outcome.

Financial Impact

Significant risk reduction for Keysight, eliminating potential liability from patent infringement claims. No damages awarded; instead, patent claims were invalidated.

Risk Factors

  • Centripetal may seek further appeal to the Supreme Court, though likelihood is low for a nonprecedential Federal Circuit decision.
  • Remaining patent claims not challenged in this proceeding could still pose risks if asserted in future litigation.
