K.T. (Sunny) Cherian is a leading intellectual property lawyer and Co-Head of the U.S. Intellectual Property Practice of Hogan Lovells. His practice focuses on complex patent litigation and licensing covering a wide range of technologies. He has been lead and co-lead trial counsel in dozens of complex patent cases, has successfully argued appeals before the Court of Appeals for the Federal Circuit, and has represented clients before the International Trade Commission under Section 337. Sunny has been consistently named as a “Northern California Super Lawyer" in the area of Intellectual Property Litigation by Super Lawyers magazine every year for 10 years. He is also listed in Best Lawyers in America.

Sunny has handled numerous cases in the International Trade Commission (ITC), Eastern District of Texas, the Northern, Central, and Southern Districts of California, Delaware, Virginia, Michigan, and other jurisdictions throughout the United States. He has represented his clients in all aspects of patent litigation, including trials, Markman hearings, motions for summary judgment, depositions, and other appearances. He has also assisted clients in all aspects of licensing including the negotiation, drafting, and resolution of disputes. Most recently Sunny and his team prevailed in a motion for summary judgment granting non-infringement of 16 claims in a multi-patent action involving Radio Frequency Identification technology. He was also successful in eliminating another three patents from being asserted against the same client. Ultimately, the matter settled with the patent holder paying the client $6.5M. In another matter, Sunny was able to invalidate the patent- in-suit after prominent industry participants had settled with the patent holder. 

Sunny has tackled dozens of complex patent litigations involving a variety of technologies such as electronics, integrated circuits, networking, software, analogue circuits, and mechanical devices. By utilizing a combination of legal, technical, and team-building skills, Sunny is able to provide his clients with a motivated and talented team that works collegially in obtaining cost-effective results. As a result of his technology experience, he is able to assist clients on a cost-effective basis with licensing and other contractual disputes that have technology related underpinnings.

  • Chrimar Systems, Incorporated v. Foundry Networks, Incorporated. Represented Brocade Communications (acquired Foundry Networks, Inc.) against Chrimar Systems in the Eastern District of Michigan. The matter involved allegations of patent infringement by Foundry’s incorporation of the “Power-Over-Ethernet” industry standard.

Foundry fought to invalidate the asserted claims and after seven years of protracted litigation, we won summary judgment of patent invalidity based upon obviousness of the asserted claim, and the case was dismissed. Chrimar appealed, but the Federal Circuit summarily affirmed the lower court.
