Trademark Law in San Francisco, CA

Dergosits & Noah LLP assists clients nationally and internationally with clearance searches, trademark applications and registrations, and portfolio management, as well as securing international registrations and enforcement. We represent clients in litigation involving trademark and trade dress infringement throughout the federal courts.


Before a trademark can be safely adopted, we perform clearance searches to determine whether the desired mark is available for adoption, use, and registration. By reviewing the search reports thoroughly, we can conclusively determine the extent to which a mark is already being used and whether its use would adversely impact our client's use and registration of the mark.


Trademark licensing agreements can be complex, taking months to negotiate and finalize. We have extensive experience drafting agreements on behalf of both licensees and trademark owners. We will protect our clients' trademark rights while allowing them to capitalize on these valuable assets.

Prosecution and Filing

Once we adequately clear a particular mark for adoption, use and registration, we assist clients in preparing all of the necessary documentation and filing and prosecuting the application before the United States Patent and Trademark Office (USPTO), including Intent to Use and Use in Commerce applications.

Our clients often want to ensure their trademarks are protected in countries around the world wehere their products and services are sold. We frequently assist clients with filing trademark applications under the Madrid Protocol, which allows trademark holders to obtain protection in multiple countries by filing a single application. We also work with an extensive network of attorneys around the world to secure registrations in the countries where our clients do business.

Trademark Trial and Appeal Board Matters

Throughout the trademark registration process before the USPTO, other parties can challenge a trademark application or registration by filing an opposition or cancellation.

We regularly appear before the Trademark Trial and Appeal Board (TTAB) to defend opposition proceedings and pursue oppositions on our clients' behalf against other trademark applications. We also pursue and defend cancellation proceedings.
