The firm maintains a significant presence with offices in major U.S. cities, including Chicago, Los Angeles, New York, Philadelphia, Phoenix, and Washington, D.C.

Clark Hill's Intellectual Property Litigation practice is equipped to handle high-stakes disputes across a broad spectrum of technologies, including patents, trademarks, trade secrets, unfair competition, false advertising, and copyright infringement. The firm’s patent litigators possess technical expertise spanning electrical, mechanical, and medical devices, as well as software, chemical compounds, and semiconductor technologies. While the firm's practice description indicates experience representing both patentees and defendants in infringement claims, the firm's tracked cases show appearances exclusively on the defendant side.

A notable engagement for the firm includes its representation of Tianma Microelectronics Co., Ltd. in the patent disputes with LG Display Co., Ltd. and Tianma Microelectronics Co., Ltd. et al., which involved OLED and automotive display technologies. These disputes, encompassing lawsuits in U.S. District Courts in Texas, were resolved through a settlement in May 2026. In a related development, the USPTO Director issued a precedential ruling in March 2026 denying Tianma's inter partes review (IPR) petitions against LG Display patents due to issues of legal standing. The firm also represented Moskowitz Family LLC as Lead Counsel in Medtronic, Inc. v. Moskowitz Family LLC.

Clark Hill actively engages in PTAB proceedings, with its IP litigation team possessing experience in the United States Patent and Trademark Office (USPTO), including AIA trials, oppositions, and cancellation petitions. Key partners in the firm's IP litigation practice include John K. Kim, who has extensive experience in patent, trademark, and copyright litigation and has prosecuted AIA trials before the PTAB. Other prominent practitioners include Ahmed J. Davis, who served as Lead Counsel in a tracked patent case, and Ralph W. Selitto, a registered patent lawyer with decades of experience in patent, trademark, and copyright litigation, alongside IP portfolio management.
