Company profile

Company overview. Ricoh Company, Ltd. (TYO: 7752; ADR: RICOY) is a Japanese multinational founded in 1936 and headquartered at 1-3-6 Nakamagome, Ota, Tokyo. It is publicly listed on the Tokyo Stock Exchange (Prime) and is not a subsidiary. Company/financial-data disclosures put headcount at roughly 75,000–76,000 employees and trailing twelve-month revenue around ¥2.6 trillion (approximately $17 billion) for the fiscal year ended March 2026; figures vary slightly by source and reporting date.

Products / services. Ricoh is an operating company with four reported business segments: Digital Services (office MFPs, laser printers, scanners, IT infrastructure and managed services, business-process services, and software such as DocuWare and RICOH kintone plus); Digital Products (manufacture and OEM production of MFPs, printers, scanners and electronic units); Graphic Communications (commercial cut-sheet and continuous-feed production printers, industrial inkjet heads, imaging systems); and Industrial Solutions (thermal paper/media, precision optical components and modules, factory-automation cameras and inspection equipment). Other operations include digital and 360-degree cameras (Pentax/THETA), environmental and healthcare ventures. Ricoh historically manufactured optical disc drive technology.

Patent-litigation posture. Ricoh is an operating company and a two-way litigant, consistent with its single plaintiff and single defendant appearance in the tracked data. It has asserted its own patents against disc-drive makers while also defending counterclaims and a declaratory-judgment suit. It also runs a substantial outbound licensing program; no plaintiff-friendly venue clustering appears in the tracked cases.

Notable cases. Ricoh Company, Ltd. v. Quanta Computer Inc. et al. (W.D. Wis., filed Aug. 24, 2006) asserted optical recording/formatting patents (e.g., U.S. 5,063,552; 6,172,955; 6,631,109) against Quanta and ASUS entities; a 2009 jury returned a $14.5 million verdict against Quanta Storage, and the court denied a permanent injunction in 2010, noting Ricoh no longer made disc drives. ASUSTeK Computer Inc. et al. v. Ricoh Company, Ltd. (N.D. Cal., filed April 6, 2007) was a declaratory-relief action brought after ASUS was dismissed from the Wisconsin case; the court held Ricoh collaterally estopped from asserting claims 1 and 4 of the '109 patent following the Wisconsin invalidity finding.
