The Verdict & Legal Analysis
Outcome
On March 20, 2024, Webroot, Inc., Open Text, Inc., and Sophos Ltd. filed a joint stipulation of dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii). All infringement claims and counterclaims were dismissed WITH PREJUDICE, while all defenses and non-infringement counterclaims were dismissed WITHOUT PREJUDICE. Each party agreed to bear its own costs and attorneys’ fees. No damages award, injunctive relief, or public licensing terms were disclosed, indicating a privately negotiated resolution.
Key Legal Issues
The case, heard in the Western District of Texas by Judge Alan D. Albright, was a patent infringement action asserting eight patents against four Sophos cybersecurity products. The breadth of the assertion across both legacy and newer patents suggests a comprehensive litigation strategy. The dismissal with prejudice of all infringement claims prevents the plaintiffs from reasserting these specific allegations. The preservation of non-infringement defenses without prejudice allows Sophos to maintain certain legal positions for future needs. The mutual cost-bearing arrangement suggests a negotiated exit rather than a contested judicial ruling under 35 U.S.C. § 285.

Eight U.S. patents were asserted: US8418250B2, US8726389B2, US9413721B2, US9578045B2, US10257224B2, US10284591B2, US10599844B2, and US11409869B2 — covering cybersecurity and network threat detection technologies.
The parties filed a joint stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii). Dismissal with prejudice of infringement claims prevents re-filing of the same allegations; the specific terms of any underlying agreement were not publicly disclosed.
It reinforces that multi-patent assertions against core security products create significant settlement pressure, and that well-resourced defendants can negotiate resolution without judicial determination of validity or infringement.
