With more than 60 jury trials to verdict as lead counsel, Tim has a skill set not often found - a licensed patent lawyer with lots of experience on his feet in courtrooms persuading juries and judges, combined also with a busy practice of IP guidance. He knows how IP is put together and he knows how it's challenged - he's seen a lot of it, from both sides.

Intellectual property is the product of the creative mind. Tim views his role with his Clients' work to navigate that creativity to results meaningful to his Clients - guiding his Clients from strategic counseling to registration, to commercialization, to licensing, and, if necessary, to litigation. Tim focuses his practice 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.

PatentLitigationAfter two years of litigation and on the eve of trial, Tim helped his client, a patentee, secure a consent injunction for willful patent infringements (along with several other remedies).
•Tim represented a multinational corporation accused of patent infringement. He helped reach a settlement after early discovery revealed severe flaws in the plaintiffs' case.
•Tim defended an innovative client accused of patent infringement. After two years of litigation, the plaintiff voluntarily dismissed the case to avoid risking a ruling on pending summary judgment motions.
•Represented a plaintiff against a patent infringer. Despite the defendants' arguments of claim invalidity, a settlement was reached.
•Tim secured summary judgment of patent infringement and patent claim validity against a copyist competitor.

Trademark DisputesTim successfully defended a client accused of trademark infringement for using Google ad words that had been registered as federal trademarks. The case settled and the client was able to continue using the search terms.
•He defended a client against a challenge seeking the cancellation of a federal registration. The matter successfully settled after three years of litigation.
•Tim represented a client against a departing employee who took website data and passwords with him. He immediately initiated litigation which resulted in the recovery of the client's URL, content and passwords.

Copyright LitigationTim defended a company accused of copyright infringement. Following extensive discovery, a settlement was reached before trial.

Misappropriation of IdentityAfter a client of Tim ran radio ads, a celebrity sued alleging misappropriation of identity. A settlement was reached for nominal damages.

Outside Nexsen Pruet

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.
