Practice Areas Overview

Based in San Francisco, Dergosits & Noah LLP is one of the Bay Area's preeminent intellectual property law firms, representing a diverse array of clients nationwide and internationally in all aspects of patents, trademarks, and copyrights, including intellectual property litigation matters. 

We have secured and protected intellectual property for clients from virtually every sector of the science, technology, and entertainment industries, including biotechnology, semiconductors, computer software and hardware, video entertainment systems, food and wine, consumer products, wired and wireless communication networks, automotive, pharmaceuticals, medical equipment, action toys, construction technology, and clean energy research and development.

In particular, we have extensive experience assisting clients in the following areas:


We assist clients with every aspect of patent law, including preparation and prosecution of domestic and foreign patent applications, patent infringement litigation, and licensing issues.  Our goal is to help our clients avoid infringement lawsuits wherever possible; as such, we regular provide due diligence, non-infringement opinions, and freedom to operate searches.  When disputes do arise, our experienced litigators pursue and defend patent infringement claims in federal court and handle contested matters before the U.S. Patent and Trademark Office.  In addition, we have developed a particular expertise in the area of requests for re-examination.


Trademarks and service marks consist of any word, name, symbol, device, or other designation that distinguishes a company's goods and services from those of a competitor.  As such, protecting these rights can be crucial to ensuring a business's continued profitability and distinctiveness in the marketplace. 

We have extensive experience handling all aspects of trademark prosecution, including domestic and foreign preparation, filing, and clearance searches.  We are also experienced litigators, and regularly pursue and defend trademark and trade dress infringement litigation involving likelihood of confusion and dilution claims.  In addition to trying cases in federal courts nationwide, our attorneys regularly appear before the United States Patent and Trademark Office and its Trademark Trial and Appeal Board to argue opposition and cancellation matters.

Internet and Social Networking

Internet-based companies and businesses with an online presence face unique intellectual property concerns.  At Dergosits & Noah LLP, we advise clients on the full range of issues involving trademark, trade dress, copyright infringement, and domain name "cyber-squatting" that can commonly arise in this context.  We have a particular wealth of experience representing developers that supply tools, applications, and widgets to social networking websites.   


Copyright law protects the rights of an author to distribute, publish, copy, display or perform, and alter his or her original work, while also granting him or her the ability to license these rights to others.  Although registering for copyright protection is simpler than obtaining patent protection or trademark registration, copyright infringement litigation can often prove complex.  Our attorneys have extensive experience pursuing and defending infringement claims based on all aspects of copyright law, including the Digital Millennium Copyright Act (DMCA).

Trade Secrets

Trade secrets include any information a business's competitors cannot easily learn from public domain sources that could help them achieve financial gain, and can often be among the most valuable information a business can possess.  We counsel companies who have hired former employees of competitors on how to avoid violating trade secret laws.  We also counsel our clients on the creation of policies and procedures to protect their valuable trade secret assets.  When disputes arise, we represent them in trade secret litigation and unfair competition matters. 

Clean Technology Research and Development

As the number of patents awarded for clean technology innovations continues to increase, it has become increasingly important for companies to be proactive about protecting their intellectual property in this fast-growing and highly competitive area.  By staying abreast of the latest technological advances in the field of clean energy, we can advise clients on the best ways to identify and protect their own innovations.
