The Charlotte-Mecklenburg Hospital Authority (CMHA), commonly known as Atrium Health, is a large, not-for-profit healthcare system headquartered in Charlotte, North Carolina, United States. Established on October 7, 1940, it operates as a municipal hospital authority under North Carolina law, classifying it as a unit of local government. As of December 2022, Atrium Health merged with Advocate Aurora Health to form Advocate Health, the third-largest nonprofit health system in the United States, which employs approximately 150,000 people. Atrium Health's Charlotte and Georgia operations alone reported $14.2 billion in revenue in 2025.
Atrium Health provides a comprehensive range of healthcare and wellness services across North Carolina, South Carolina, Georgia, and Alabama. Its offerings include academic medical centers, numerous hospitals, freestanding emergency departments, physician practices, and specialized care centers. Major service lines encompass pediatric care (including developmental and behavioral pediatrics), cancer care through the Levine Cancer Institute, and heart care via the Sanger Heart & Vascular Institute, as well as organ transplants, burn treatments, and musculoskeletal programs.
In patent litigation, Charlotte-Mecklenburg Hospital Authority appears to be an operating company primarily defending against intellectual property assertions. Its tracked history shows one case as a defendant and zero as a plaintiff. This posture suggests that the entity is a target of patent litigation rather than an active enforcer of its own patent portfolio.
The single tracked case, Lone Star SCM Systems, LP v. Charlotte-Mecklenburg Hospital Authority, was filed on November 13, 2023, in the North Carolina Western District Court. This aligns with Atrium Health's headquarters jurisdiction. The company's significant growth and recent combination into Advocate Health highlight its substantial presence and operational complexity within the healthcare industry.
