Donald Lee Jackson

Donald Lee Jackson is a Partner at Daignault Iyer, focusing his practice on intellectual property litigation, with a particular emphasis on patent infringement matters. His technical background includes experience with advanced airborne radar, sensing, and surveillance systems from his prior work as a defense contractor. His firm handles a range of technologies, including electrical engineering, computer science, networking, integrated and semiconductor chip technologies, biomedical, chemical, and mechanical engineering, and medical devices.

Jackson has experience representing both plaintiffs and defendants in patent disputes. While his firm, Daignault Iyer, focuses on "Patent Monetization" for patent owners and Hatch-Waxman litigation for generic drug companies, the tracked cases indicate a slight preference for the defendant side, with three defendant appearances and one plaintiff appearance. He has served as lead counsel in numerous patent infringement litigations across the country, including in key patent venues like the Eastern and Western Districts of Texas, the District of Delaware, and the Northern and Central Districts of California.

Among his notable representations, Jackson has been involved in cases for Dynamic Mesh Networks, Inc. (d/b/a MeshDynamics). In one instance, Dynamic Mesh Networks, Inc. filed suit against Cisco Systems, Inc. in the Eastern District of Texas, asserting patents related to mesh networking architectures and Forward Error Correction (FEC) technology, which was voluntarily dismissed without prejudice after 59 days. His practice also extends to post-grant proceedings, including appearances before the U.S. Patent and Trademark Office's Patent Trial and Appeal Board (PTAB). For example, his firm represented Dynamic Mesh Networks, Inc. in an IPR proceeding (IPR2025-01523) where institution was denied following the patent owner's disclaimer of claims. Jackson's firm also highlights successful outcomes, such as a generic drug company client prevailing at trial in a Hatch-Waxman litigation, subsequently winning on appeal, and generating substantial sales.

Prior to joining Daignault Iyer, Jackson was a Partner at Rimon Falkenfort, Davidson Berquist Jackson & Gowdey LLP, and Nixon & Vanderhye P.C. While his firm profile does not detail his specific bar admissions or education, his extensive experience as a patent litigator is well-documented.
