Actionable Insight • Neutral

Monitor for upcoming trial dates or settlement developments on the '777 Patent. The denial of the Daubert motion keeps plaintiff's case intact, modestly increasing Cisco's litigation exposure. The mooted Interrupt Patents are a minor positive. Expected near-term stock impact is negligible unless a significant damages figure emerges in later proceedings.

Executive Summary

The Eastern District of Texas denied Cisco's motion to exclude plaintiff Eireog's expert (Dr. Brogioli) under Daubert, allowing his opinions on patent benefits and infringement for the '777 Patent to proceed. Separately, the Interrupt Patents claims against Cisco were mooted after Eireog elected to pursue only the '777 Patent. The ruling is a procedural loss for Cisco but does not resolve liability or damages.
