Company profile

Qualcomm Inc., legally known as QUALCOMM Incorporated, is an American multinational technology corporation headquartered in San Diego, California. Founded in July 1985, the company is publicly traded on the NASDAQ stock exchange under the ticker symbol QCOM. As of 2025, Qualcomm reported approximately 52,000 employees and generated $44.28 billion in revenue. Its market capitalization was around $238.02 billion as of May 27, 2026.

Qualcomm develops and designs foundational technologies for global communications and computing, including next-generation mobile networks, smart devices, and semiconductors. The company operates through three primary segments: Qualcomm CDMA Technologies (QCT), Qualcomm Technology Licensing (QTL), and Qualcomm Strategic Initiatives (QSI). The QCT segment is responsible for developing and supplying integrated circuits and system software for mobile devices, automotive systems (connectivity, digital cockpit, ADAS/AD), and Internet of Things (IoT) products, notably its Snapdragon processors. The QTL segment licenses Qualcomm's extensive intellectual property portfolio, which includes standard-essential patents for 3G, 4G, and 5G cellular technologies. Qualcomm is also expanding into areas such as embedded artificial intelligence, augmented reality, virtual reality, and data center chips.

Based on the provided patent litigation data, Qualcomm Inc. has a posture characteristic of an operating company defending against patent assertions, with no recorded cases as a plaintiff and one tracked case as a defendant. This indicates the company primarily focuses on developing and commercializing its technologies rather than initiating patent enforcement suits from an acquired portfolio.

The company's sole tracked litigation, Longitude Licensing Limited et al. v. Apple Inc. et al., filed on February 18, 2025, in the U.S. International Trade Commission (USITC), lists Qualcomm as a defendant. This case is currently the only recorded patent litigation involving Qualcomm in our database.
