Competitor Doosan Bobcat filed patent infringement lawsuits against Caterpillar in the U.S. and Europe in early December 2025. The lawsuits allege that Caterpillar equipment—including skid-steer loaders, excavators, and dozers—misuses Bobcat’s patented technologies for machine control and maneuverability. Doosan Bobcat seeks damages and a potential import ban on the contested equipment in the United States. The legal action introduces uncertainty for Caterpillar regarding its intellectual property and the availability of key products. As of December 9, 2025, Caterpillar has not issued a public response to the allegations. This litigation follows a period of strong stock performance for Caterpillar in 2025. The potential for an import ban on popular machinery could impact future sales and investor confidence.
