It is publicly listed on the Tokyo Stock Exchange (Ticker: 7752) and trades OTC in the US as RICOY. Per Ricoh's own company data, consolidated net sales were ¥2,608.3 billion for the fiscal year ended March 31, 2026, with 75,635 employees on a consolidated basis. It operates in roughly 200 countries and regions. Ricoh is an operating company, not a holding or shell entity.
Products / services. Ricoh organizes operations into segments: Digital Services (office multifunction printers (MFPs), laser printers, scanners, and IT/document-management and managed-print services); Digital Products (development and OEM production of imaging equipment and embedded/industrial computers plus electronic components); Graphic Communications (commercial and industrial inkjet printing systems, cut-sheet and continuous-feed printers, inkjet heads); Industrial Solutions (thermal paper and thermal media, industrial optical modules and precision mechanical components); and Other (digital and 360-degree cameras, environment and healthcare ventures). It sells under its own brand as well as Savin, Lanier, and Nashuatec.
Patent-litigation posture. Ricoh is an operating company defending against patent-assertion suits, not an asserter. The tracked data show 0 cases as plaintiff and 1 as defendant, consistent with a target of NPE litigation rather than an active filer.
Notable case. RAH Color Technologies LLC v. Ricoh Americas Corp. et al. (E.D. Pa., No. 2:15-cv-05203), filed September 16, 2015, named Ricoh Americas Corp., Ricoh Americas Holdings, Ricoh USA, and Ricoh Company, Ltd. RAH Color Technologies—a Virginia company formed in 2005 by inventor Dr. Richard Holub as a licensing vehicle, and characterized as an NPE/PAE by Unified Patents—asserted a portfolio of color-management and color-reproduction patents (e.g., the '870, '251, '008, '546, '444, '704, '314 patents) covering printer and camera color calibration. The case was filed in the Eastern District of Pennsylvania (not a notorious plaintiff venue); Ricoh filed invalidity counterclaims, some of which were dismissed with leave to amend, and the case closed February 16, 2017.
RAH Color Technologies LLC asserted the '546 patent against Ricoh Americas Corp., Ricoh Co. Ltd., and Ricoh USA Inc. The case produced a published pleading-standards opinion and was terminated/closed on or about Feb. 16, 2017.
