- Ad Innovations, LLC v. BMW of North America, LLC, 3:25-cv-00179, S.D. Tex.
Represented BMW Group in a patent infringement suit filed by non-practicing entity Ad Innovations, LLC, which alleged that BMW 7 Series sedans infringed U.S. Patent No. 8,594,341, covering systems for switching between multiple audio channels using interior microphones. The suit, filed in June 2025, was voluntarily dismissed just two months later when Ad Innovations conceded it could not prove infringement. Finnegan secured a swift, cost-effective dismissal of the case. - Beacon Navigation GmbH v. Bayerische Motoren Werke AG et al, 1:11-cv-00931, D. Del.; Certain Automotive GPS Navigation Systems (Beacon Navigation v. Audi), 337-TA-814, ITC; Beacon Navigation GmbH v. Bayerische Motoren Werke AG et al, 2:13-cv-11410, E.D. Mich.
Represented BMW Group against Beacon Navigation in a complex investigation involving 50+ automobile manufacturers and, in 2024, brought the 13-year patent litigation saga to a close. Beacon sued BMW in the District of Delaware, asserting three patents directed to improved navigation systems, including U.S. Patent No. 5,862,511, and filed a parallel ITC investigation. While others settled, BMW persisted, refusing to capitulate with a settlement. After strategic venue transfers, stays, and six USPTO reexaminations, Beacon was left with only two surviving claims. Despite years of litigation, Beacon failed to produce evidence of infringement. Its expert’s report, based solely on software code, confirmed non-infringement. The Michigan court granted summary judgment in BMW’s favor, ending Beacon’s campaign. - Bayerische Motoren Werke AG et al v. Arigna Technology Limited, 1:23-cv-01190, D.D.C.
Represented the BMW Group in a declaratory judgment action for noninfringement and invalidity of U.S. Patent No. 8,289,082, as part of its long-fought battle against Arigna, in which the court dismissed Arigna’s counterclaim of patent infringement with prejudice. This dismissal came after BMW secured a royalty free covenant-not-to-sue on the asserted patent, ensuring that Arigna cannot reassert its claims. This outcome represented a definitive victory for BMW, bringing a close to U.S. litigation surrounding the ’082 patent, the last of four patents initially asserted by Arigna as part of its broader enforcement campaign.
