Intellectual Property Litigation

San Francisco law firm Dergosits & Noah LLP represents clients nationwide in intellectual property (IP) cases, including patent, trademark, and copyright infringement matters throughout the nation's federal courts, the Patent Trial and Appeal Board (PTAB) and the Trademark Trial and Appeal Board (TTAB). We also handle trade secret and unfair competition matters through the work of our intellectual property litigation attorneys in San Francisco, CA.

IP counseling and litigation is often complex, lengthy, and expensive. These cases involve intricate legal principals and require an in-depth understanding of the underlying technology; our sophisticated understanding of both law and technology puts us in a strong position to represent clients in IP litigation. Additionally, our strong background in transactional matters makes us especially familiar with the administrative procedures for procuring patent, trademark, and copyright protection, allowing us to uncover potential issues that might affect the outcome of the litigation.


Our broad technical and legal knowledge allows us to represent plaintiffs and defendants in even the most complex patent infringement litigation. We often utilize requests for reexamination and other Post Grant procedures at PTAB, which can be particularly useful for defendants in these cases. Our attorneys argue patent appeals before the PTAB and the Federal Circuit.


Vigilant enforcement and maintenance of trademark rights is necessary to prevent possible confusion, dilution, or both. We represent plaintiffs and defendants in trademark litigation and also handle cancellation and opposition matters before the Trademark Trial and Appeal Board (TTAB). We also supervise international counsel in trademark enforcement proceedings in countries around the world.


Copyright litigation is complex, requiring a thorough understanding of both the Copyright Statute and how this law has been interpreted by the particular circuit court in which the case is filed. We represent clients in disputes involving all types of copyrighted materials, including computer programs, visual art, sound recordings, and any literary, musical, dramatic, sculptural, pictorial, and architectural works.
