Tim Walker focuses on patent litigation involving computer software, computer hardware and chemistry. His cases have involved object-oriented software; encryption software, databases; networking hardware and software; wireless communications hardware and software; computer conferencing; computer monitors; computer chip design, manufacturing and packaging; medical imaging devices; enzymatic clinical assays; microbial production of food supplements; epoxy resins; robotics; and batteries.

Mr. Walker has more than thirty-five years of experience as a litigator, including first-chair trial and appellate experience. He has had a leading role representing clients in district court, at the ITC, and before the Federal Circuit. He has prepared and presented technology tutorials, argued claim constructions, argued summary judgment motions, presented and cross-examined expert witnesses, presented opening and closing arguments and argued appeals to the Federal Circuit.

Mr. Walker’s educational foundation in science makes him comfortable with complex technologies and allows him to respond in real time to unexpected technical questions from judges, new but flawed arguments by opposing counsel, and evasions by hostile expert witnesses. His strategic approach includes an analysis of the basic scientific concepts at issue combined with rigorous legal analysis.

Mr. Walker is a regular participant in Stanford Law School’s Trial Advocacy Workshop, critiquing students on their performance of a variety of deposition and courtroom exercises.
