Toshiba America Information Systems, Inc. (TAIS) is a U.S. subsidiary headquartered in Irvine, California, established in 1981. It is an independent operating company owned by Toshiba America, Inc., itself a subsidiary of Toshiba Corporation of Tokyo (formerly TSE: 6502; taken private in 2023 under a Japan Industrial Partners-led consortium). Company documents have cited roughly 1,200 employees and 1990s press reporting put U.S. headcount near 1,650; no current, verifiable headcount or revenue figure was found, so those are dated.
TAIS provides sales, marketing and service for Toshiba-branded products in the U.S. and Latin America. Divisions over time included Client Solutions (notebooks, tablets), Digital Display, Branded Storage, Imaging Systems (security, medical and manufacturing imaging), Telecommunication Systems (IP business telephony and unified communications) and Industrial Solutions & Services (IoT development, analytics, IT services). Its scope has changed materially: TAIS assigned its PC master agreement to Toshiba America Client Solutions, Inc., which Sharp Corporation acquired (80.1%, 2018), deconsolidated from Toshiba Group on October 1, 2018, and renamed Dynabook Americas, Inc. in April 2019. The Toshiba-branded notebook business is no longer part of Toshiba Group.
On litigation posture, TAIS appears in the tracked data only as a defendant — 0 plaintiff cases, 2 defendant cases — consistent with an operating company defending against an outside patent holder rather than an asserter. Both entries are the same March 7, 2017 dispute: Macronix International Co., Ltd. et al. v. Toshiba Corporation et al., filed in the U.S. District Court for the Southern District of California and as an ITC Section 337 complaint (Inv. No. 337-TA-1046, "Certain Non-Volatile Memory Devices and Products Containing Same"), asserting U.S. Patents 6,552,360, 6,788,602 and 8,035,417 against NAND flash memory and products containing it. Venue was TAIS's home district, not an NPE-favored forum such as the Eastern District of Texas.
Other respondents included Toshiba Corporation, Toshiba America, Inc., Toshiba America Electronic Components, Inc. and Toshiba Information Equipment (Philippines); Toshiba Memory Corporation was added in June 2017. The ALJ found no violation in April 2018; the Commission reviewed and found a violation as to claim 6 of the '602 patent, issued remedial orders in October 2018, then rescinded them in November 2018 following the parties' license and settlement agreement.
