Sony

Sony Group Corporation (TSE: 6758; NYSE: SONY), commonly "Sony," is a Japanese public company headquartered at 1-7-1 Konan, Minato-ku, Tokyo, founded May 7, 1946 and listed since 1958. Per its own corporate data page, it reported consolidated sales of roughly ¥12.5 trillion for the fiscal year ended March 31, 2026, with consolidated headcount cited at about 112,300 (other financial data providers list figures in the 94,900–113,000 range depending on date). It is a widely held public parent, not a subsidiary of another group; Sony Electronics Inc. is the U.S. operating subsidiary named in the litigation below.

Operations. Sony operates as a diversified entertainment and technology conglomerate across several reporting segments: Game & Network Services (PlayStation consoles, services, and first-party software), Music, Pictures, Imaging & Sensing Solutions (CMOS image sensors and related components), Entertainment Technology & Services (televisions, digital cameras, audio, and professional/broadcast equipment), and Financial Services (primarily Japanese insurance and banking operations). It is an operating company with real products and services, not a patent-holding vehicle.

Litigation posture. The tracked cases show Sony primarily as a defendant being attacked: 2 defendant appearances versus 1 plaintiff appearance, and the "plaintiff" case is a Patent Trial and Appeal Board petition, i.e., defensive inter partes review rather than an infringement assertion. This is the classic operating-company profile — targeted by a non-practicing entity and responding at the PTAB. There is no evidence in the data of Sony asserting patents offensively against operating rivals.

Notable cases. The tracked matters arise from the Realtime Adaptive Streaming LLC campaign. Realtime sued Sony Electronics Inc. in D. Del. (1:17-cv-01693), part of a broad assertion program against streaming and consumer-electronics defendants (Netflix, Hulu, Amazon, Google, Samsung, Broadcom, Intel, Apple, and others) asserting patents on adaptive/bandwidth-sensitive data compression, many filed in the Eastern District of Texas and District of Colorado. Sony's PTAB petition, Sony v. Realtime Adaptive Streaming LLC (2018-07-31), is a defensive challenge to those compression patents. The third tracked matter, Realtime Adaptive Streaming LLC v. Hulu et al., sits before the Judicial Panel on Multidistrict Litigation, reflecting coordination of Realtime's many parallel suits. Realtime is a Texas LLC widely characterized as a patent assertion entity; court and PTAB records show several of its asserted compression claims were found invalid or canceled in related cases.
