Tim chairs Nexsen Pruet's Intellectual Property practice group. A registered patent attorney with more than 60 jury trials to verdict as lead counsel, Tim has a skill set not often found: lots of experience in courtrooms persuading juries and judges, combined with a busy practice of providing IP guidance and pursuing patents and trademarks. He knows how IP is put together and he knows how it's threatened. He's seen a lot of it, from both sides. Which explains Tim's enthusiasm and confidence about NP's Intellectual Property practice group - certainty in proven abilities, “walk-the-talk” experience, and eagerness to think outside the box.

Intellectual property is the product of the creative mind. Tim views his role with his Clients' work to navigate that creativity to meaningful results - guiding his Clients from strategic counseling to registration, to commercialization, to licensing, and, if necessary, to litigation. His practice focuses exclusively on IP, but his work runs that gamut: patents, trademarks, copyrights, and trade secrets. His Clients include individuals, start-ups, established companies, and multi-national corporations.

Much of Tim's work is from referrals from other lawyers, in his view the highest compliment a lawyer can receive. Moreover, he is proud to be a lawyers' lawyer, having represented his attorney peers and their law firms in IP disputes.

Tim volunteers with JDRF, working to cure Type 1 diabetes. “I don't have a personal connection to Type 1 diabetes; I just believe in JDRF and the people associated with it.” His involvement started years ago with a JDRF “Ride to Cure Diabetes” bicycle ride. Since then, he has served for five years as the National Head Coach for JDRF's Ride program and for three years as the national chair of JDRF's Ride Committee. He was recently elected to JDRF's International Board of Directors. “The Ride to Cure is a powerful effort. It fundraises for JDRF, but it also provides the opportunity to show that we're going to turn Type One into Type None. After that, we'll have one more Ride, just to celebrate that we did it.”
