4 cases as defendant.
I'll verify the key facts with some searches before writing.
Let me verify the NPE plaintiff and the case context.
Overview. Toshiba Corporation is a Japanese diversified electronics and infrastructure group headquartered in Minato-ku, Tokyo (with plans to relocate its head office to Kawasaki). It traces its roots to 1875 and was renamed Toshiba in 1978 as the successor to the Shibaura Engineering Works / Tokyo Electric Company merger. It was listed on the Tokyo Stock Exchange (ticker 6502) for 74 years until December 2023, when a consortium led by private equity firm Japan Industrial Partners (with Orix, Chubu Electric Power and Rohm) completed a roughly ¥2 trillion buyout and took the company private. Toshiba reports approximately 106,000 employees and FY2023 net sales of about ¥3.2 trillion.
Products / operations. Toshiba is an operating company, not a licensing vehicle. Its segments include Energy Systems & Solutions (thermal, nuclear and hydro power generation equipment), Infrastructure Systems & Solutions (water treatment, transport, broadcasting, battery systems such as SCiB), Building Solutions (elevators, lighting, HVAC), Retail & Printing Solutions (POS systems and multifunction printers, largely via publicly listed Toshiba Tec), Electronic Devices & Storage Solutions (power devices, small-signal and optical semiconductors, analog/mixed-signal ICs, HDDs), and Digital Solutions (IT services). It has divested several former units, including its NAND flash memory business (reorganized as Kioxia), medical, TV and laptop operations.
Litigation posture. Toshiba appears in the database only as a defendant (1 case, 0 as plaintiff), consistent with a large operating company targeted by patent assertion entities rather than an active plaintiff. The sole tracked suit was filed in the District of Delaware, not the Eastern District of Texas.
Notable case. Collabo Innovations, Inc. v. Toshiba Corporation et al., No. 1:15-cv-00608 (D. Del., filed July 16, 2015), named Toshiba plus Toshiba America Inc. and Toshiba America Electronic Components Inc. Collabo Innovations is a subsidiary of Wi-LAN/Quarterhill, a patent-licensing entity; the asserted portfolio covered image-sensing technology and was acquired from Panasonic in 2013. WiLAN announced on December 30, 2015 that Collabo had entered a patent license agreement with Toshiba, resolving the Delaware litigation on confidential terms.
Monument Peak Ventures asserted several patents, including 7684090, against Toshiba entities. The court granted Toshiba's motion to dismiss on § 101 patentable-subject-matter grounds, and MPV appealed.
ITC Section 337 investigation by Macronix against Toshiba entities asserting the '360, '602, and '417 patents. The ALJ found no violation as to the '360 and '417 patents, while the Commission found a violation as to claim 6 of the '602 patent and issued remedial orders; those orders were rescinded on November 13, 2018 based on a Macronix-Toshiba license and settlement agreement.
Macronix sued Toshiba entities in S.D. Cal. asserting U.S. Patents 6,552,360, 6,788,602, and 8,035,417. The case was stayed pending the parallel ITC investigation and dismissed on October 11, 2018 after the Macronix-Toshiba settlement.
Collabo Innovations sued Toshiba Corporation, Toshiba America Inc., and Toshiba America Electronic Components Inc. in D. Del. The case was filed on 2015-07-16; the record does not confirm whether US 6,166,405 was asserted or the outcome.
