Jointly steered by Chicago’s Douglas Winthrop and New York’s Dina Hayes, Arnold & Porter litigates across a litany of luxury goods, tech, pharma and consumer products industries, to name a few, providing its clients with substantive trademark, domain name and unfair competition expertise. In New York, veteran practitioner Paul Llewellyn is well-positioned to advise on infringement litigation and general enforcement mandates and Dori Hanswirth bolsters the practice with her extensive experience across TTAB proceedings, prosecutions, asserting trademark claims and a host of trademark litigation. In Chicago, Michael Harris‘s arsenal of skills extends across trademark, trade dress and trade secret lawsuits, and Christopher Renk frequently handles matters pertaining to computer software, consumer electronics and product design for a diverse roster of clients. New York-based Theresa House and Matthew Salzmann are other names to note in the group.
