David J. Silbert

David J. Silbert is a seasoned patent litigator at Keker, Van Nest & Peters LLP, a prominent San Francisco-based litigation boutique. He maintains an active license with the State Bar of California (Bar #173128). Silbert's practice at the firm broadly encompasses intellectual property litigation, alongside business litigation, criminal defense, professional liability, and securities and corporate finance matters.

Silbert predominantly represents defendants in patent disputes, aligning with the firm's reputation for defending leading innovators and product developers such as Google, Genentech, and Comcast in high-stakes intellectual property cases. His experience in patent litigation spans various technology areas, with a noted focus on computer architecture, software, and security, in addition to some work in chemical and biotechnology fields.

A notable engagement for Silbert includes his representation of X (formerly Twitter) in a patent licensing dispute with Adeia in the U.S. District Court for the Northern District of California (case number 3:23-cv-06151). This case, where Silbert, Sharif Jacob, and Kristen Lovin represented X, reached a settlement in June 2024. While Keker, Van Nest & Peters is recognized for its trial prowess, there is no indication that Silbert regularly appears in Inter Partes Review (IPR) or Post-Grant Review (PGR) proceedings before the Patent Trial and Appeal Board (PTAB).

Silbert earned his legal degree from UC Hastings College of the Law. He has accumulated 26 years of experience in his legal practice.
