Tim Carroll is viewed by clients and peers as a go-to patent litigator who has successfully litigated the cutting-edge technology issues of the day, including patent cases involving medical devices, green technologies, mobile apps, location-based services, messaging systems, Wi-Fi-enabled thermostats, and content management platforms. Through his representation of leading and emerging technology companies, Tim has secured trial wins, preliminary injunctions, forced his adversaries to stipulate to noninfringement, won summary judgment awards, earned a substantial attorneys’ fee award and prevailed in claim construction arguments. Tim has also led many joint-defense groups involving some of the largest and most sophisticated companies and law firms in the United States.

Tim recently achieved several victories for companies immersed in patent and licensing disputes.

  • In Smith & Nephew v. Arthrex Inc., Tim was asked to serve as first chair on a case for trial that involved second-generation products. Notwithstanding a prior verdict against Arthrex and a series of adverse rulings from the case involving first generation products, Tim steered Arthrex into a favorable settlement on the eve of trial. Along the way, Tim and his team earned a victory by knocking out plaintiff expert’s liability testing, which left the plaintiff with a lack of liability evidence to present to the jury.
  • In Advanced Transit Dynamics v. Ridge Corp., Tim was the lead trial lawyer in an injunction hearing held by Judge O’Connell of the U.S. District Court for the Central District of California. Following that hearing, Judge O’Connell entered a preliminary injunction in favor of Tim’s client, Advance Transit, forcing Ridge to cease making, selling or marketing its competing green technology offering.
  • In NorthMobileTech v. Simon Property Group, which was the first U.S. case involving mobile-app technology to advance to a substantive ruling, Tim led the effort that resulted in summary judgment on noninfringement grounds and an award of almost $400,000 of fees in favor of his client.
  • In Unified Messaging Systems v. Vanguard Group, Inc., Tim was selected, by a joint-defense group of more than 50 defendants, as one of the two lawyers to argue at the Markman hearing. The result for Vanguard and the other defendants was a resounding win, which forced the plaintiff to stipulate to noninfringement and dismiss the case.
  • In Gardere, Wynne & Sewell v. Open Text, Inc., Tim led the effort to obtain a summary judgment ruling against a Dallas law firm, in Texas State Court, in a case involving licensing issues associated with the delivery of content management tools.

Tim also has extensive experience in inter partes reviews (IPRs) and other post-grant proceedings, and he is actively involved in three separate IPRs. In addition to litigation, Tim has counseled more than 100 global businesses, including two FORTUNE 15 companies, on adopting and implementing lawfully compliant information management programs as well as on e-discovery and litigation readiness initiatives.

Recognized as a patent litigation standout by Intellectual Asset Management Patent 1000, Tim is a member of the Illinois bar and the trial bar of the Northern District of Illinois, and he is admitted to practice before some of the busiest patent litigation dockets in the United States, including the Eastern District of Texas, the Western District of Wisconsin and the Northern District of Illinois. Tim is frequently called for media commentary on compliance and e-discovery issues, and he has been quoted in such publications as the Chicago Tribune, Compliance Week, Metropolitan Corporate Counsel and the Privacy and Data Law Journal. Tim also has been routinely recognized by Illinois Super Lawyers and as a “Leading Lawyer” for IP by the Leading Lawyers Network.
