Farnan LLP: Patent Litigation Summary
Farnan LLP is a specialized litigation boutique based in Wilmington, Delaware. The firm was founded by Joseph J. Farnan, Jr., after his 25-year tenure as a United States District Court Judge for the District of Delaware, a premier venue for patent litigation. Farnan LLP is not an AmLaw-ranked firm but is recognized by industry publications like Chambers USA as a key player in the Delaware IP market, functioning as a respected regional patent shop that frequently serves as local counsel for out-of-state firms.
The firm's patent litigation practice handles complex commercial disputes across various technologies. Its public track record includes representing plaintiffs in the software and pharmaceutical sectors, evidenced by its role in securing an $84.5 million jury verdict for Densify against VMware and achieving findings of infringement and validity in Hatch-Waxman litigation for the blockbuster drug Eliquis®. The firm's known representations, such as for Datacloud Technologies LLC against Microsoft and Gigex, Inc. against Yahoo!, further underscore its experience in software and internet-related patent matters.
Based on authoritative data and industry commentary, Farnan LLP primarily represents patent holders. Both tracked cases show the firm acting as local counsel for the plaintiff, and Chambers USA notes partner Brian Farnan's "vast experience acting for plaintiffs in patent litigation." The firm’s public case history and attorney biographies consistently emphasize a focus on representing plaintiffs in high-stakes litigation.
The firm's key practitioners include partners Brian E. Farnan and Michael J. Farnan. Both are listed as counsel in the firm's tracked patent cases and are recognized by publications such as Chambers, Super Lawyers, and IAM Patent 1000 for their litigation work. The firm's notable cases, Datacloud Technologies LLC v. Microsoft Corporation and Gigex, Inc. v. Yahoo! Inc., were both resolved via dismissals that suggest settlement. There is no publicly available information to suggest the firm maintains a significant inter partes review (IPR) or other PTAB-focused practice.
