Defendant
6 cases as defendant.
General Motors Company, commonly known as GM, is a publicly-traded multinational automotive manufacturer founded in 1908. Headquartered in Detroit, Michigan, the company trades on the New York Stock Exchange under the ticker symbol GM. As one of the world's largest automakers, GM employs approximately 156,000 to 165,000 people. For its most recent full fiscal year, the company reported revenues in the range of $185 billion.
GM's primary business is the design, manufacture, and sale of cars, trucks, and automobile parts. The company's core vehicle brands are Chevrolet, Buick, GMC, and Cadillac. In addition to vehicle manufacturing, GM provides automotive financing and leasing through GM Financial and offers vehicle safety, security, and information services via its OnStar subsidiary. The company also serves the defense industry and sells automotive parts under the ACDelco brand name.
The provided data, showing five patent lawsuits filed against GM and only one filed by the company, indicates the patent-litigation posture of an operating company primarily defending itself against infringement claims. These suits have been filed in plaintiff-friendly jurisdictions such as the Eastern and Western Districts of Texas, a common venue for patent assertion. The single case filed by GM is a proceeding at the Patent Trial and Appeal Board, a common defensive measure used by operating companies to challenge the validity of patents being asserted against them.
The tracked cases show GM defending against suits from several non-practicing entities (NPEs). Notably, the defendants in these cases include both General Motors Company and its subsidiary, General Motors Holdings LLC. The lawsuits involve various technologies, as suggested by the names of the plaintiffs, such as AutoConnect Holdings LLC, Optimum Vector Dynamics LLC, and Chemtron Research LLC. This pattern of litigation is typical for a large technology-focused manufacturing company like General Motors.
