McDermott Will & Emery

As of May 2026, McDermott Will & Emery operates as an international "BigLaw" firm, which public sources indicate merged with Schulte Roth & Zabel in 2025 and is now known as McDermott Will & Schulte. The firm is consistently ranked in the AmLaw 100 and has its headquarters in Chicago, with more than 20 offices across North America and Europe. It is a full-service firm with a diversified corporate practice, including a significant intellectual property group recognized by industry publications like Chambers and IAM Patent 1000.

The firm's patent litigation practice handles complex, high-stakes disputes for clients in the technology and life sciences sectors. Based on the provided case list, the firm’s recent work has been exclusively on the defense side, representing technology companies such as Keysight Technologies and Trend Micro. This aligns with the firm's broader description of representing established commercial and financial enterprises. The matters range from network security technology in Centripetal Networks, LLC v. Keysight Technologies, Inc. to software in Intellectual Ventures I LLC v. Trend Micro Incorporated et al.

McDermott maintains an active practice before the Patent Trial and Appeal Board (PTAB), handling inter partes review (IPR) proceedings for its clients. The firm’s IP group is noted for representing clients in key patent litigation venues, including the district courts of Texas and Delaware, as well as at the US International Trade Commission (ITC). While specific outcomes in the tracked cases are not detailed in public records, the firm has a history of notable results, including a significant 2013 Federal Circuit appellate victory for Hanmi Pharmaceutical in a Hatch-Waxman Act case.

The firm's IP litigation practice is led by partner Nicole M. Jantzi, who has been recognized as an "IP STAR" by Managing IP. Attorneys from the provided case list with a significant IP profile at the firm include Robert W. Zelnick, a registered patent attorney who primarily focuses on trademark litigation. Another attorney on the list, Paul M. Schoenhard, has also been recognized as a leading IP litigator; however, legal industry press from March 2026 reported his move to McGuireWoods.
