It is publicly traded (TSE Prime, ticker 6952) with no parent company. Per its FY2025 (year ended March 31, 2025) results, consolidated net sales were ¥261.76 billion and consolidated employees numbered 8,801; recent third-party profiles cite consolidated headcount near 9,200 and revenue around US$1.8 billion.

Products / operations. Casio is an operating company that develops, manufactures and sells consumer and business electronics. Its four reporting segments are Timepieces, Consumer, Systems and Other. Principal products include watches and clocks (G-SHOCK, Baby-G, OCEANUS, EDIFICE, SHEEN, PRO TREK brands), electronic calculators (including scientific and graphing models), electronic dictionaries, label printers, electronic musical instruments and digital pianos (Privia, CELVIANO, Casiotone), data projectors, handheld terminals, electronic cash registers, management-support systems, and molded parts and molds. Timepieces account for roughly two-thirds of revenue. Casio exited mobile phones (2013) and compact digital cameras (2018).

Patent-litigation posture. Casio appears in the tracked data once, as a defendant, with zero plaintiff-side filings — the profile of an operating company being attacked rather than an active two-way litigant. The sole case sits in the Eastern District of Texas, a plaintiff-friendly venue.

Notable case. Fleet Connect Solutions LLC v. Casio Computer Co., Ltd. (2:24-cv-00240, E.D. Tex., filed April 12, 2024).
