David L. Larson

Based on available court records and publications, David L. Larson is a patent litigator who was formerly of counsel with McDermott Will & Emery, based in the firm's Menlo Park, California, office. His practice appears focused on defending technology companies in complex patent infringement suits. The authoritative case data shows him exclusively representing defendants, a posture consistent with his role in other publicly documented litigation.

Mr. Larson's work covers software and computer networking technology. He was listed as counsel for the defendant in Intellectual Ventures I LLC v. Trend Micro Incorporated et al. That case concluded with a significant victory for his client, Trend Micro, when a Delaware federal judge invalidated the two asserted patents on the grounds they were directed at abstract ideas, preempting a jury trial that was scheduled to begin in May 2015. Mr. Larson also served as co-counsel for Extreme Networks in a patent infringement case against Enterasys Networks involving computer network switches and routers that concluded in 2013.

No public information was found regarding Mr. Larson's experience in IPR or other PTAB proceedings. His current professional affiliation is not clearly established in publicly available sources, as his biography no longer appears on the McDermott Will & Emery website. Details regarding his bar admissions and legal education are not available from reliably sourced legal publications.
