Preparing for the 2025 Proxy and Annual Reporting Season: Key Issues and Considerations

Susan has significant experience obtaining and defeating temporary restraining orders and preliminary injunctions in trademark and copyright matters, including complex contributory infringement matters on behalf of brands. A leading trademark lawyer for both contentious and non-contentious matters, Susan manages multibillion-dollar global trademark portfolios; negotiates multijurisdictional disputes; and leads IP due diligence for brand acquisitions. She has achieved significant victories for clients before the United States Patent and Trademark Office, the Trademark Trial and Appeal Board and the National Arbitration Forum. Susan’s copyright experience includes the protection and enforcement of works such as fabric designs, artwork and architectural plans, and she represents clients on moral rights under the Visual Artists Rights Act.

Susan also focuses on advertising litigation, defending clients against false claims under the Lanham Act. She is relied upon to provide important counsel on trademark, copyright and publicity issues in advertising campaigns, and she trains companies on U.S. advertising law compliance and counsels on Section 5 of the FTC Act, covering testimonials, endorsements, online marketing, product efficacy claims, the FTC’s Green Guides and "Made in the USA" claims.

In addition, Susan advises clients on the intersection of intellectual property and emerging technologies, particularly artificial intelligence, offering guidance on compliance policies, AI best practices, vendor agreement review and risk management.

Susan has been named as an “IP Trailblazer” by the National Law Journal and an “IP Star” multiple times by Managing Intellectual Property. She is also regularly recognized by the World Trademark Review as a leading trademark practitioner (both litigation and non-contentious).
