In 2014, Law360 named K&L Gates a Practice Group of the Year for intellectual property. The publication cited our “bevy of high profile wins over the past year…”

K&L Gates’ Intellectual Property Litigation practice is a sophisticated, worldwide enterprise with experience in all aspects of IP litigation. Our clients include those protecting emerging communications technologies, novel drug therapies, iconic brands, trade secrets, copyrights, and other proprietary information. Law360 named us a “Practice Group of the Year” for IP Law, and the National Law Journal named our practice to its “IP Hot List” of the top practices in the U.S. The NLJ said of K&L Gates, “Big firm. Big wins.”

Our practice is distinguished by:

  • Strong technology depth with over 100 U.S. Patent and Trademark Office (PTO)-registered professionals with backgrounds in electrical, mechanical, chemical, biological, software, physics, and material sciences, including approximately 20 with Ph.D.s.
  • Extensive experience in virtually every venue in the United States, including IP litigation hot spots such as the Eastern District of Texas, District of Delaware, Eastern District of Virginia, Central and Northern Districts of California, Northern District of Illinois, Western District of Wisconsin, and the Federal Circuit.
  • Top-ranked trial lawyers with extensive jury and bench experience, and a record of successful outcomes.
  • Depth and scope in Asia Pacific with 11 regional offices, including four in Australia, to meet the growing intellectual property needs presented by the region’s extraordinary economic growth and increasing influence in the global economy.
  • Extensive experience before the U.S. International Trade Commission (ITC) with over 20 Section 337 Investigations ongoing or recently concluded, including ten trials.

Our practice incorporates a robust Patent Office Litigation practice, combining our knowledge of patent litigation, patent office adversarial proceedings, and patent procurement.

Our 100 IP litigators devote their practices to IP litigation, and combine the many complex facets of IP to marshal every resource necessary on behalf of clients. We are steeped in the practice of intellectual property law, including the Federal Circuit’s constantly changing jurisprudence, International Trade Commission procedures, preliminary and permanent injunction practice, and bench and jury trials. We handle every scale of litigation, from large, complex multi-jurisdiction matters and bet-your-company confrontations between industry leaders, to litigation involving non-practicing entities, to modest license dispute and piracy matters.

Above all else, we view the world through our clients’ eyes. Our litigation strategies and tactics advance our clients’ business goals, not our own.

We represented Abercrombie & Fitch in a high-profile case in California federal court brought by Levi Strauss & Co. involving claims of unfair competition, trademark infringement, and dilution. The jury returned a unanimous verdict in favor of Abercrombie & Fitch on all claims. The case was profiled in the Daily Journal – California's largest legal publication – as one of the Top 10 "Defense Wins" in California in 2008.
We defended Acer, Silicon Motion, Transcend and Apacer in an ITC investigation filed by SanDisk. The patents at issue describe methods for storing and organizing data in flash memory devices. K&L Gates was lead trial counsel in the non-infringement part of the two-week trial in Washington, D.C. The ITC ruled accused flash memory devices did not infringe the SanDisk patents.
Our lawyers secured a key victory for Archer Daniels Midland after two weeks of trial before a jury in Syracuse, N.Y. The jury unanimously found ADM's environmentally friendly Caliber brand road-deicing products did not infringe the two asserted patents.
We represented Sigma International (now Baxter Healthcare) in a patent infringement jury trial against CareFusion Corp. in the Southern District of California. The patent at issue related to occlusion sensors for infusion pumps. CareFusion sought $171 million in damages and a permanent injunction. After a two-week trial, the jury returned a complete defense verdict. The verdict received extensive coverage by media outlets such as Bloomberg and IP Law360, and was named one of the top 2012 defense verdicts in California by The Daily Journal.
We are counsel for Amazon.com, Acer, Inc., and Novatel Wireless in Certain Wirless Consumer Electronic Devices and Components Thereof, No. 337-ITC-853, where complainants sought an exclusion order against the Kindle Fire. After a two-week trial, the Administrative Law Judge found no violation of Section 337 (pending).
We represented Eastman Kodak Company in litigation with Apple Computer, Inc. and Research in Motion Corporation in two simultaneous cases before the International Trade Commission and simultaneous federal court proceedings in three states alleging that technology employed in devices such as the iPhone and Blackberry infringes Kodak’s patents. The technologies at issue in the myriad suits include imaging devices such as digital cameras and video cameras, and related software, as well as printers.
Our lawyers led Microsoft Corporation’s defense in its successful seven-year battle with Apple Computer concerning Microsoft's right to develop and distribute the Windows graphic user interface. This case sharply limited the applicability of “look and feel” concepts in copyright infringement disputes involving software. Microsoft won the case on summary judgment by the trial court and successfully defended that judgment through appeals.
We won a complete victory in the French civil court for a producer of diagnostic instruments for critical care and hemostasis. Our client charged a competitor with infringement of the client’s patents on a method of diagnosing a blood coagulation disorder and with product disparagement through statements the defendant made in advertising. After a trial, the court concluded our client’s patents were valid and were infringed by the defendant, prohibited the defendant from further sales of the test, directed the defendant to make corrective advertising, and as an initial damages ruling, awarded more than €2.3 million to our client. The damages award was based in part on U.S. theories of damages not typically followed in French patent law.
Our lawyers secured victory for semiconductor companies Spansion and AMD in the International Trade Commission and Northern District of California. The case was a high-stake, multi-billion dollar litigation. The ITC ruled that the firm’s clients, along with additional defendants, do not infringe semiconductor assembly patents being asserted by Tessera, Inc.
