David John Hoffman

David John Hoffman maintains a patent litigation practice primarily representing plaintiffs, often in matters involving technology companies. Operating his own firm, Law Office David J. Hoffman, he has appeared as counsel or local counsel in patent infringement actions in U.S. district courts. His office is based in New York, NY.

Mr. Hoffman's practice areas, as evidenced by his tracked cases, include wireless communications, mobile device technology, and software relating to user interfaces and information discovery. In Mesa Digital, LLC v. US Mobile, Inc., the asserted patent concerned wireless handheld multimedia devices capable of communicating across multiple wireless standards. The case Linfo IP, LLC v. Trustpilot, Inc. involved a patent directed to systems, methods, and user interfaces for discovering and presenting information in text content.

His case history indicates a focus on representing patent assertion entities (PAEs) or non-practicing entities (NPEs), with both tracked appearances on the plaintiff side. For example, Mesa Digital, LLC is identified as an NPE. In Linfo IP, LLC v. Trustpilot, Inc., where Mr. Hoffman served as local counsel, the plaintiff's asserted patent was found ineligible under 35 U.S.C. § 101, leading to the dismissal of the case. The Mesa Digital case was voluntarily dismissed without prejudice by the plaintiff. No specific information regarding Mr. Hoffman's involvement in PTAB or IPR proceedings is reliably available.

Mr. Hoffman is admitted to the New York Bar.
