Boies Schiller Flexner is known for its balanced approach to litigation, regularly representing both plaintiffs and defendants. While their tracked patent litigation cases show a slight tilt toward plaintiff representation (6 plaintiff-side, 3 defendant-side), the firm's patent litigation practice explicitly highlights recovering over $1 billion for patent holders and defeating billions in claims for defense clients. This dual capacity allows them to leverage insights from both perspectives.

In notable recent patent litigation, Boies Schiller Flexner is representing HandsFree Labs Licensing, LLC and Fast IP, LLC in ongoing infringement lawsuits against Skechers U.S.A., Inc. in the Eastern District of Texas. These cases, filed in July 2025, allege willful infringement of multiple utility and design patents related to hands-free footwear technology. The firm also has a notable PTAB/IPR practice, frequently appearing before the Patent Trial and Appeal Board and the International Trade Commission. For example, the firm is defending Fast IP, LLC against an IPR challenge (IPR2026-00342) initiated by Skechers in April 2026 concerning a rapid-entry footwear patent.

Key partners leading the firm's patent litigation practice include Ryan D. Dykal and Blair M. Jacobs, who serve as co-leaders. Other prominent partners in this area are Mark D. Schafer, Philip Eckert, John S. Holley, and Christina A. Ondrick. Many of these partners joined the firm as part of a strategic expansion of its patent litigation capabilities over the past two years.
