Kat Welch

Kat’s trademark practice spans the full lifecycle of a brand, from selecting and registering trademarks to managing portfolios and enforcing rights when someone else gets a little too close. She has particular experience with trademark enforcement and disputes before the Trademark Trial and Appeal Board (TTAB), where she handles oppositions, cancellations, discovery, motions, settlement negotiations, and broader enforcement strategy. She also counsels clients on trademark clearance and prosecution as well as strategies for protecting their brands in the United States and abroad.

Kat also works on the other side of the brand equation: advertising. She counsels clients on comparative advertising, labeling, influencer campaigns, sweepstakes and promotions, pricing and promotional claims, gaming, and other pre-litigation advertising issues. Her work increasingly involves emerging areas of advertising regulation, including sports betting and AI disclosure requirements. She enjoys helping clients turn ambitious marketing ideas into campaigns that can actually make it out of the conference room.

Kat represents businesses of all sizes and across industries, with particular experience in beverage, technology, consumer products, and toys. She works with everyone from growing local businesses seeking their first trademark registration to established companies defending valuable brands. Her approach is practical and business-minded: rather than treating legal advice as an obstacle to a business objective, Kat looks for ways to make the law work for the client.

A particular strength of Kat is her ability to see brands from both sides: as a lawyer who helps companies build, protect, and defend what they have created, and as a consumer who knows that brands influence what people notice, trust, and ultimately buy. She brings that perspective—and a genuine enthusiasm for her clients’ businesses—to every matter she handles.
