Bronze - Individuals: enforcement and litigation

Snell & Wilmer has trademark talent in California, Arizona and DC, and a burnished national reputation on all fronts of brands practice. The firm’s IP group continued its expansion in 2021 following major lateral recruitment moves in 2020, giving clients with diverse portfolios more resources and options. In the capital, John Dabney, Mary Hallerman and Richard Kim have settled in extremely well since their arrival in Spring 2020. According to foreign associates, they are “a great set of practitioners with all the wisdom and firepower needed to help out in the most difficult situations”. Working collaboratively, they undertake wide-ranging clearance, prosecution and enforcement work for Medtronic, Pebble Beach Company and many other prestigious names. Dabney and Hallerman are admired for their contentious proficiency, which they put on clear display in their recent representation of Oregon Brewing Company in a multi-layered dispute over its ROGUE trademark with Excelled Sheepskin & Leather Coat Company, in which they ultimately established that their client held nationwide rights to the relevant mark for apparel, and that Excelled’s use of the mark caused a likelihood of confusion. Coming in for special praise, Kim is “unparalleled in his ability to give strategic and pragmatic advice addressing USPTO examination procedure and office actions”.
