Eric S. Tautfest

Patent litigation is different from other areas of law. The technologies involved can be very complex, 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 business and the technologies at issue so if a trial is necessary, I can boil it down to terms that the judge or jury will understand, which helps them focus on the real issues at stake.

Chair of the Intellectual Property Department, Eric Tautfest is a skilled litigator and trial lawyer who represents clients in various intellectual property disputes, with a particular focus on patent infringement litigation and trial in federal courts across the country. He has successfully prosecuted and defended numerous patent infringement claims involving a wide variety of technologies, including wireless telecommunications, software, fiber optics, computer displays, image compression, medical devices, the Internet plus many more.

Clients also rely on Eric to protect and defend their rights in cases involving trademarks, trade secrets, copyrights, and other IP disputes. In addition, Eric guides clients through many types of IP transactional matters, from conducting due diligence and asset valuations to structuring license and purchase/sale agreements.

With considerable experience representing clients on both sides of the docket, and having served as in-house counsel, Eric brings a holistic and business-minded approach to every case. While Eric is known for being an aggressive litigator and courtroom advocate when necessary, a jury trial may not always be the best strategy. He focuses on fully developing his client’s strategy from case inception, which leads to a more efficient resolution and, if trial is necessary, a better trial outcome.

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 IP assets. This background also helps Eric visualize what a successful outcome looks like for the decision makers on both sides of a case. Once he has a solid grasp of the competing interests involved, Eric can explore creative ways to bridge the gap and achieve a positive outcome for his clients. Based on his reputation for reaching effective outcomes outside the courtroom, clients have called on Eric to serve as settlement counsel in several patent infringement cases.
