James Cai founded SAC Attorneys LLP after serving as in-house legal counsel for Yahoo! Inc. His practice focuses on corporate law, intellectual property, immigration, and estate planning.

Mr. Cai believes in relationship lawyering and has a client-driven practice. He practices law the old fashioned way – giving each client this full attention with prompt responses, thorough research and analysis, aggressive representation and careful attention to details, in both transactional and litigation matters. As a result, most of his clients are repeat and long term clients, including individuals, small businesses, non-profit organizations and public companies. He has successfully represented leading companies and non-profit organizations such as Intel, Nokia Venture (now known as Blue Run Venture), HiSense, Webex, Yulong Group, OFO, Su Zhou Industrial Park, San Jose State University, and Ballet San Jose.

Before founding SAC Attorneys, Mr. Cai served as in-house counsel for Yahoo! Inc. He also practiced law with Morrison & Foerster, LLP and Gray Cary Ware & Freidenrich, LLP (now known as DLA Piper Rudnick Gray Cary), two of the largest law firms in California. Mr. Cai holds a Juris Doctor, Magna Cum Laude, from Temple University School of Law in Philadelphia, graduating in the top 5% of his class.

Mr. Cai was selected as a member in Premier Lawyers of America, an invitation-only organization which recognizes the top 1% of attorneys in America, based on the criteria of case outcomes, legal experience, professional achievements, educational history, certifications, peer and client feedback, ratings and reviews, professionalism and ethics. In 2019, Mr. Cai was recognized by Association of American Trial Lawyers for excellence in business law.

Mr. Cai is admitted to practice in California, United States District Court for the Northern District of California, United States Court of Appeals for the Ninth Circuit and before the United States Patent and Trademark Office.

Client Reviews
Mr. Cai Is a Diligent Attorney. My sister and I were defendants in a civil litigation case. We hired James Cai and his law firm, SAC Attorneys LLP. Mr. Cai is a diligent attorney and responded to our questions in a timely fashion. He and his staff were very helpful in keeping us informed of the proceedings of the case and in explaining each step. Mr. Cai is also very conscientious of fees and costs, and avoided unnecessary charges. The results of the Summary Adjudication sided with us. The Court Trial resulted in the “Final Statement of Decision” and “Judgment after Court Trial” overwhelmingly siding with us. Cynthia F.
I Am Truly Impressed. After spending a significant amount of time, money and efforts with my previous counsel at a larger law firm without getting meaningful results, I transferred my employment matter to SAC Attorneys LLP. The attorneys there were able to understand the complex situations of my case and put together an aggressive litigation strategy. We were able to file a compelling complaint within a week and forced the opposing party, which was represented by one of the largest law firms in California, to make a substantial settlement offer shortly thereafter. I am truly impressed by the no nonsense and results oriented approach by SAC Attorneys LLP attorneys. A job well done! X. Gao
They Took Time to Understand Our Technology. I am the founder of a bioinformatics start-up in the Silicon Valley and chose SAC Attorneys LLP as our corporate counsels. Their attorneys have great experience with high tech start-ups and were able to offer a highly competitive service plan while not sacrificing a bit of their quality of services. They took time to understand our technology and provided value added services by introducing investors and job candidates to us. We regard our attorneys at SAC Attorneys LLP not only as our legal advisors but also our venture partners. Dr. Pete S.
