Eric S. Tautfest

Patent litigation is incredibly different from other areas of law. The technologies involved can be extremely complex and typically have their own unique jargon, making it difficult to explain how they work to someone outside the client’s industry. My approach in each case is to learn everything I can about my client’s technology so when the trial date arrives, I can boil it down to simple terms that any judge or jury can understand and help them focus on the real issues at stake.

Chair of the Intellectual Property Department, Eric Tautfest is a skilled patent litigator and trial lawyer who focuses on developing practical and creative patent monetization strategies and implementing aggressive enforcement litigation and licensing programs throughout the entire patent life cycle. He has successfully prosecuted and defended patent infringement claims before federal courts across the country involving diverse technologies, including wireless telecommunications, software, fiber optics, computer displays, image compression plus many more.

Earlier in his career, Eric worked exclusively on the plaintiff’s side of patent infringement litigation with a strong incentive to resolve cases both quickly, favorably and efficiently. He carries this mindset to the defense side of his practice as well, doing whatever it takes each day to push cases forward and achieve his clients’ goals in the most economical way possible. Based on his reputation for reaching timely and resourceful resolutions, clients have called on Eric to serve as settlement counsel in numerous patent infringement cases. 

Before joining the firm, Eric held an in-house position that gave him a better understanding of the industry from his clients’ perspective and hands-on experience resolving the challenges businesses face while protecting their technologies. This background has made a big impact on Eric’s approach to litigation. In each case, Eric not only focuses on understanding the business needs of his client, but also those of the decision makers on the other side. Once he has a solid grasp of the competing interests involved, Eric can explore creative ways to satisfy the concerns of opposing parties that may stand in the way of reaching the best outcome for his clients.
