David Ludwig represents technology companies, manufacturers, and patent owners in high-stakes patent disputes in U.S. district courts, before the Patent Trial and Appeal Board, and on appeal to the U.S. Court of Appeals for the Federal Circuit. He handles both plaintiff-side enforcement and defense-side litigation and has served as counsel in district court trials, Federal Circuit appeals, and inter partes review proceedings. His matters regularly involve products with annual sales in the hundreds of millions of dollars and technologies spanning electronics, software, telecommunications, pharmaceuticals, medical devices, and scientific instruments.
Clients turn to David when a matter demands quick command of complex technology, clear strategic judgment, and execution under significant time pressure. With a background in physics and an M.B.A., he brings both technical fluency and business perspective to patent disputes. He helps clients assess merits early, focus the case on the issues most likely to drive outcome, and develop positions on infringement, validity, damages, and remedies that remain coherent through discovery, expert work, dispositive motions, trial, and appeal.
David is particularly effective in matters that do not stay in one forum. He works with clients to coordinate district court litigation, PTAB strategy, and Federal Circuit considerations so positions remain aligned and leverage is preserved. His practice includes claim construction strategy, expert-intensive records, patent-eligibility issues, prior art challenges, damages posture, and appeal-aware preservation of outcome-determinative issues.
