DENVER, Dec. 12, 2012 /PRNewswire/ -- Denver-based health care information technology and services provider HealthTrio, LLC, has filed a patent infringement lawsuit against Aetna, Inc. (NYSE: AET) and two Aetna subsidiaries. In the lawsuit filed Dec. 11, 2012, in the U.S. District Court for the District of Colorado, attorneys for HealthTrio allege that Hartford, Conn.-based Aetna and subsidiaries ActiveHealth Management, Inc. and Medicity, Inc. have infringed 10 HealthTrio information technology patents: U.S. Patent Nos. 7,428,494; 7,440,904; 7,509,264; 7,831,446; 8,073,710; 8,214,234; 8,229,760; 8,265,954; 8,131,563; and 8,321,239. The inventions protected by these patents are methods and systems for connecting all health care participants (including patients, doctors, other health care providers, and health insurance companies) to improve the quality of care, decrease costs, and streamline administrative processes. HealthTrio's patented solutions facilitate the real-time sharing of information via easy-to-access online portals for consumers and their health care providers. Such solutions are now considered best practices for health care participants to promote compliance with recent federal regulations regarding the digitization of medical records. The HealthTrio patents resulted from the pioneering work of Dr. Malik Hasan, founder and CEO of HealthTrio, and his co-inventors' extensive knowledge of both the information-sharing needs of health care participants, and also the functional characteristics of modern health care information technology systems. HealthTrio invests significant resources in its ongoing research and development efforts, to promote its innovative products and technology, and to secure intellectual property protection for its inventions. "HealthTrio's ultimate goal is to create a patient-centric electronic health care record that is comprehensive in its scope and that facilitates information-sharing among all health care participants – patients, hospitals, health care providers, and health insurance companies," said Dr. Hasan. "We have been innovators and market-leaders in the field of health care information technology dating back to the founding of our company."
