Ricoh Sues Zoom in Delaware Over Patent Infringement.

Ricoh Company, Ltd. has filed a patent infringement lawsuit against Zoom Communications, Inc. in the U.S. District Court for the District of Delaware. The case, Ricoh Company, Ltd. v. Zoom Communications, Inc. (No. 1:25-cv-01095), was filed on August 29, 2025, and marks the latest move by the Japanese tech giant to protect its intellectual property portfolio in the United States. According to court records, Ricoh alleges that Zoom has infringed on one or more of its patents, bringing the case under 35 U.S.C. § 271, the federal statute governing patent infringement. Specific patents and technologies at issue have not yet been disclosed in the publicly available docket, but the filing signals potential friction between Ricoh’s enterprise technology business and Zoom’s dominant position in video conferencing and communications solutions.

The lawsuit is at an early stage, with the initial complaint being the only filing recorded so far. Zoom has not yet filed a response, and no hearing dates or schedules have been set. The outcome of the case could carry significant implications for both companies, especially as competition in workplace collaboration and enterprise communications continues to intensify. Observers note that Delaware remains a favored venue for patent disputes, given its expertise in handling complex intellectual property matters. This case will be closely watched for its potential to reshape licensing negotiations or business practices between Ricoh and Zoom.
