Nintendo Co., Ltd. (任天堂株式会社; TSE Prime: 7974; US ADR NTDOY) is a Japanese entertainment company headquartered at 11-1 Kamitoba Hokotate-cho, Minami-ku, Kyoto. It was founded in 1889 by Fusajiro Yamauchi and incorporated in its present form in 1947; its shares have traded in Tokyo since 1962. It is a public, independent company with no parent, reporting roughly 8,700 consolidated employees and trailing-twelve-month revenue near ¥2.3 trillion (≈$15 billion) as of the fiscal year ended March 2026 (Barron's, FT, PitchBook profiles; nintendo.co.jp).
Products / operations. Nintendo develops, manufactures and sells dedicated video game hardware and software: home consoles in the Nintendo Switch family, handheld devices, first-party game software, accessories and figures (amiibo), digital storefronts and subscription services (Nintendo Switch Online), mobile titles, and licensed merchandise and IP. Hardware production is largely outsourced; US sales and operations run through Nintendo of America, Inc. (Redmond, WA). Nintendo is an operating company, not a shell licensor.
Patent-litigation posture. In the tracked data Nintendo appears in exactly one matter — as a defendant, with zero appearances as plaintiff. That pattern is consistent with an operating company being targeted rather than an aggressor. The single venue is the U.S. International Trade Commission, not a district court; no tracked cases sit in the Eastern District of Texas.
Notable case. That matter is Technology Properties Limited LLC et al. v. Acer Inc. et al. (filed July 24, 2012), a Section 337 complaint brought by patent-licensing entities Technology Properties Limited LLC, Phoenix Digital Solutions LLC and Patriot Scientific Corp. They asserted U.S. Patent No. 5,809,336 ("High performance microprocessor having variable speed system clock") — part of the "Moore Microprocessor Patent" portfolio — against 24 respondents including Nintendo, Amazon, Samsung and LG, covering wireless consumer electronics such as handheld game consoles. The ITC instituted Investigation No. 337-TA-853; the ALJ found none of the accused products infringed, and the Commission terminated the investigation in 2014 without a Section 337 violation. Parallel district court suits were filed in the Northern District of California.
