Jeanne M. Gillsâ unparalleled commitment to advocating for her clients, combined with her ability to formulate solutions at a deeply strategic level, has earned her a national reputation in intellectual property litigation and for crafting her clientsâ overall IP strategy. She brings that same thought leadership to her role as vice chair of the Intellectual Property Department (leading strategic marketing and business development) and service on the firmâs Manufacturing Sector Advisory Board. Jeanne is also a former member of the firmâs Management Committee and the Compensation Committee (where she last served as chair).
As an IP partner with an electrical engineering background, Jeanneâs practice exists at the intersection of law and science. Jeanne acts as lead trial counsel in complex patent, trade secret, trademark, copyright, and unfair competition litigation and appeals â including USPTO post-grant proceedings â in diverse industries ranging from electronics to fashion to biotechnology. Her trial experience includes âbet the companyâ cases with several hundreds of millions of dollars at stake. She has been lead counsel in more than 25 PTAB proceedings, having handled IPRs, CBMs, and rare derivation proceedings, including successful defense of several PTAB decisions before the Federal Circuit. In addition to her IP litigation prowess, Jeanne is respected for providing high-value strategy development and risk mitigation counsel in transactional matters where a companyâs bottom line is IP-driven. Clients appreciate Jeanneâs ability to âread a whole situation and apply her depth of knowledge on strategies, from litigation to suggestions for negotiations.”
“Sheâs borderline genius on some of the ideas and approaches she takes with enforcement, as well as being really knowledgeable on litigation trends. She can see every approach or attack or weakness, and she strategizes.â
