1 case as defendant.
Sony DADC US Inc. is the US-based operation of Sony's global disc and digital solutions provider, a subsidiary of Sony Corporation of America. Formed in 1983 as Digital Audio Disc Corporation, a joint venture between Sony and CBS, it opened the first compact disc manufacturing plant in the United States in Terre Haute, Indiana, which remains its US headquarters. Sony acquired CBS's stake in 1985. Publicly available information on current employee count and revenue is not consistently reported, though a 2022 business directory estimated approximately 1,200 employees and over $276 million in sales.
Historically, Sony DADC was a leading manufacturer of physical media, including CDs, DVDs, UMDs, and Blu-ray discs for the entertainment, software, and video game industries. After producing over 23 billion discs from its Terre Haute facility between 1983 and 2022, the company has diversified its operations. Today, Sony DADC US provides a broader range of services, including packaging and distribution, injection molding, and information technology services. It also markets its ISO-certified cleanroom manufacturing space for industries such as electronics and semiconductors.
As an operating company, Sony DADC US Inc. has a defensive patent litigation posture. The company has been tracked as a defendant in one patent case and has not been a plaintiff. This litigation pattern is typical of a technology manufacturer and service provider being targeted by patent assertion entities. The single tracked case was filed in the U.S. District Court for the Eastern District of Texas, a venue historically favored by patent plaintiffs.
The company's only tracked litigation is Uniloc USA, Inc. et al. v. Sony Corporation of America et al., filed in 2010. In this case, Sony DADC US Inc. was named as a co-defendant alongside its parent company, Sony Corporation of America. The plaintiff, Uniloc, is a well-known non-practicing entity (NPE) that has filed numerous patent infringement lawsuits against technology companies. The suit alleged infringement of a patent related to software protection and registration systems.
A consolidated lawsuit filed against several companies in the Eastern District of Texas. It is reported that Uniloc settled with many of the defendants.
