Margret Caruso is Chair of the firm's Trademark and Copyright Practice Group. 

She devotes a substantial portion of her practice to intellectual property litigation and appellate litigation, including copyright, trademark and patent infringement, as well as unfair competition and false advertising.  Her experience is broad based, with a focus on Internet, technology, entertainment, and consumer goods companies in the copyright, trademark, design patent, trade secret, and false advertising contexts.  She has also represented plaintiffs and defendants in infringement actions concerning design, biochemical, computer, and mechanical patents.  

In addition to her trial experience and litigation of numerous temporary restraining order and preliminary injunction motions, Margret has briefed appeals to the United States Supreme Court and the Second, Fourth, and Ninth Circuits on issues of copyright, trademark, false advertising, patent, and antitrust. World Trademark Review 1000 recognized her as a “go-to lawyer for internet, entertainment, and consumer goods companies” who is “fearless in high-stakes situations.”

Margret is active in the International Trademark Association, where she has served as Chair of the Internet Committee, and is currently a member of the Copyright Committee, as well as in the Association of Business Trial Lawyers, where she serves on the Board for the Northern California chapter.
