Apple Inc., commonly known as Apple, is a publicly traded technology company founded in 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne. Headquartered in Cupertino, California, the company is a major player in consumer electronics, software, and online services. Apple trades on the NASDAQ stock exchange under the ticker symbol AAPL. As of late 2025, the company reported having approximately 166,000 full-time employees, and for the fiscal year ended September 2025, its annual revenue was approximately $416.2 billion.
Apple is an operating company that designs, manufactures, and markets a wide range of consumer technology products and services. Its major product lines include the iPhone smartphone, the iPad tablet computer, the Mac line of personal computers, the Apple Watch smartwatch, and AirPods wireless earbuds. The company also operates a significant services division, which includes the App Store, iCloud, Apple Music, Apple TV+, and Apple Pay. Apple's business model is characterized by a tightly integrated ecosystem of hardware, software, and services.
The provided data shows Apple is predominantly a defendant in patent litigation, with nine out of ten tracked cases filed against the company. This pattern is typical for a large operating company that is a frequent target for patent infringement claims, often from non-practicing entities (NPEs). The lawsuits have been filed in several jurisdictions, including the plaintiff-friendly Western and Eastern Districts of Texas, as well as the District of Delaware and the Patent Trial and Appeal Board (PTAB).

These types of entities are frequently utilized as patent assertion vehicles. The cases span several years, reflecting a continuous stream of litigation targeting Apple's high-revenue products.
