Jeffrey E. Crane Law

Jeffrey E. Crane Law, formally known as The Law Office of Jeffrey E. Crane, LLC, is an Illinois-based firm primarily operating from Northbrook, with an affiliation that includes a Chicago office through FactorLaw. Established in 2014, the firm appears to be a small litigation practice, with Jeffrey E. Crane as its principal attorney, and is recognized on Super Lawyers as having one attorney. The firm’s founder, Jeffrey E. Crane, brings over two decades of experience from major international law firms in Chicago, indicating a background of "big firm experience" in complex litigation. While not ranked among AmLaw or Chambers firms, its focus spans across commercial litigation, class actions, and intellectual property.

The firm's intellectual property litigation practice includes representing clients in patent disputes. Its primary identified specialization, based on a tracked appearance, involves mechanical or consumer product patents, as seen in Champion Power Equipment Inc. v. Harbor Freight Tools USA Inc. In this specific case, the dispute concerned allegations of infringement across 13 patents related to generator models.

Based on available tracked appearances, Jeffrey E. Crane Law has exclusively represented defendants in patent litigation, with one recorded instance on the defense side and no plaintiff-side representations. The notable outcome in the Champion Power Equipment matter saw the Eastern District of Wisconsin dismiss the infringement lawsuit on April 28, 2025, due to the "first-to-file rule," directing the substantive patent dispute to proceed in the Central District of California where the defendant had previously filed a declaratory judgment action.

While the firm lists intellectual property litigation as a practice area, comprehensive data on its PTAB or IPR practice is limited. Although an IPR proceeding related to Harbor Freight Tools USA, Inc. et al. v. Champion Power Equipment, Inc. (IPR2025-00805) was initiated, the listed counsel for the petitioner, Harbor Freight, were "Houston, Michael et al.," without direct attribution to Jeffrey E. Crane Law. Therefore, the firm's specific volume or leadership in PTAB/IPR proceedings cannot be reliably determined from public sources.

Jeffrey E. Crane serves as the key partner and founder of the Law Office of Jeffrey E. Crane, LLC. He is noted for his extensive experience in a broad range of commercial and intellectual property litigation matters.
