Tim Chen Saulsbury is a partner in the Intellectual Property Litigation group, based in the San Francisco office.

His exceptional track record has earned him consistent recognition from leading publications.  IAM Patent 1000 describes Tim as a “formidable lead trial attorney,” highlighting wins for Zoom and others.  The Daily Journal labeled him one of the “Top Intellectual Property Lawyers” in California, as well as one of California’s top 40 lawyers under the age of 40.  Bloomberg Law named Tim one of the top 40 lawyers in the country under 40, and Law360 named him one of the top 6 IP lawyers in the nation under 40.  Tim also was recognized by Benchmark Litigation (on its 40 & Under Hot List) and by The Legal 500 (for Copyright, Patent Licensing, Patent Litigation, and Trade Secrets).

Tim’s recent wins include:

• In the 6-month period from March 2025 to August 2025 alone:
• On behalf of a leading American cybersecurity company, Tim argued and won summary judgment of noninfringement in a multi-patent case in which the patentee sought hundreds of millions in damages, earning a “shout-out” in The American Lawyer’s Litigator of the Week column.
• On behalf of an eCommerce client, Tim argued and won another summary judgment of noninfringement that disposed of all three patents asserted by a competitor.
• A complete non-infringement verdict on behalf of a leading videogame company in a patent infringement suit involving one of the most popular videogames of the past decade, earning “Legal Lion” honors from Law360 and recognition in The American Lawyer’s Litigator of the Week column.
• A clean sweep plaintiff’s verdict in a Delaware patent infringement trial invovling eCommerce marketing technology.
• As lead counsel for Zoom in a six-patent case involving end-to-end encryption technology, Tim defended against claims seeking $100M+ annually and amounting to $1.5B+ over the life of the patents. After winning successive dismissal motions, Zoom moved to dismiss the entire case with prejudice. The Court issued a tentative ruling indicating that it was inclined to grant the motion, and the case promptly resolved.
• A complete defense verdict in a competitor patent trial involving USB technology that powers Apple CarPlay. Tim’s cross-examination of the lead inventor was later described as a “climactic moment” and potentially “a big reason why the jury would later reject Microchip’s case.”
• In the months leading up to that trial, Tim put together a streak of five complete walkaways as lead counsel for Zoom, Atlassian, and Brightcove.

Tim also maintains an active pro bono docket, serving as full scope counsel in a range of cases, including FTCA, First Amendment, wrongful termination, and Section 1983 matters.

Prior to joining MoFo, Tim was a partner at a national trial boutique, where he built his practice representing major technology companies in high-stakes intellectual property matters and served on the firm’s management committee.
