Dayton, Katherine Lyon

Katherine Lyon Dayton excels at developing effective strategies to secure and enforce clients’ intellectual property rights in difficult and multijurisdictional situations. She advises on international trademark clearance, registration, opposition, and cancellation actions, as well as other enforcement matters.

When clients are faced with sophisticated counterfeiters and serial infringers, Katherine identifies potential problem areas, offers practicable advice on priorities, and crafts solutions, helping to protect clients’ rights internationally. For example, she recently obtained copyright protection for several logos in China, thus providing the client with broader protection than a class-by-class trademark registration would have provided.

In addition to managing global trademark portfolios, Katherine also negotiates, drafts, and analyzes all types of copyright and trademark-related agreements, including coexistence and distribution agreements.
