Intellectual Property Law Firm Representing Tech Startups in Silicon Valley, San Mateo, Palo Alto and Throughout California

CopyrightFor many businesses in California’s Silicon Valley, intellectual property is their most valuable asset. The assets that businesses create or invest in need legal protection against infringement. The success of high-tech companies frequently depends on their success in protecting against illegal appropriation of their inventions, ideas and technology.

At SAC Attorneys LLP, we aid individuals and businesses with applications for intellectual property protection with the United State Patent and Trademark Office (USPTO) and United States Copyright Office. We also prosecute the infringement of copyrights, patents, trademarks, and trade secrets.

To learn more about domestic and international intellectual property protection, contact us for a consultation.

We are able to assist with all types of copyright matters, including:

  • Software
  • Music
  • Film
  • Books
  • Artwork
  • Technology
Application Process

The process of filing for intellectual property protection requires collaboration between clients and attorneys. We have the necessary background and experience in science, engineering and technology to help you file applications with the USPTO, and U.S. Copyright Office to get trademark, copyright, or patent protection, and assist you in the negotiation of technology licensing in order to commercialize your intellectual property.

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.
