Smith, Gambrell & Russell

Smith, Gambrell & Russell, LLP is a full-service international law firm headquartered in Atlanta, Georgia. With nearly 350 attorneys as of mid-2025, and over 400 professionals by April 2026, the firm operates across 14 domestic and international offices, including key locations such as Chicago, London, Los Angeles, New York, and Washington, D.C. The firm has been recognized on the Am Law 200 list and by Chambers USA in multiple practice areas, including Intellectual Property.

The firm's Intellectual Property Litigation Group offers comprehensive advocacy in patent, trade secret, trademark, and copyright disputes, as well as unfair competition claims. Their patent litigation experience spans a broad range of technologies, including software, semiconductors, pharmaceuticals, chemicals, manufacturing, automotive products, medical technologies, and consumer electronics. Specific representations include a defense in Earin AB v. Audio-Technica U.S., Inc. concerning wireless earbuds, and acting as defense counsel for Intrepid Automation Inc. in an IPR related to 3D printing technology, which is tied to an underlying patent infringement suit against 3D Systems Corporation.

Smith, Gambrell & Russell's IP litigation practice works both sides of disputes, representing both plaintiffs and defendants. While the firm's recent tracked appearances include two defendant-side representations and one plaintiff-side matter, their practice description confirms their engagement in both enforcement and defense strategies. The firm has publicly noted its role in leading major patent cases with market values exceeding $1 billion, securing nine-figure settlements, and arguing appeals before the Federal Circuit, including a successful patent interference appeal in 2017.

The firm maintains an active Post-Grant Proceedings practice, assisting clients as both petitioners and patent owners in Inter Partes Review (IPR), Post-Grant Review (PGR), and ex parte reexaminations before the U.S. Patent and Trademark Office (USPTO). Their involvement in Unified Patents LLC v. Intrepid Automation Inc., where they represented the patent owner Intrepid Automation in an IPR petition, highlights their experience in this area.

Key IP litigation partners include Michael Jason Riesen, who advises on IP strategy and PTAB proceedings and has a background in AI, material sciences, and electrical engineering, and John P. Moy, who focuses on patent litigation and dispute resolution across various technologies. Joseph L. Fogel, a Partner in the Litigation Practice, has extensive experience in complex business and IP disputes. William F. Long, a recognized patent litigation partner, handles patent, copyright, and trade secret disputes, including Hatch-Waxman cases. Gregory J. Kirsch serves as the head of the firm's Intellectual Property Department.
