Apple must be sued for patent infringement over Apple Watch's heart rate technology. Circuit Court of Appeals for Federal Circuit ruled today.Omni MedSci sued Apple in 2018 alleging that Apple had used its patent technology in the Apple Watch. Omni MedSci alleged that Apple met with them between 2014 and 2016, to discuss possible partnerships. However, Apple is reported to have abandoned the talks and instead used technology from four Omni patents.According to Reuters Apple tried to have the lawsuit dismissed.Mohammed Islam owns Omni MedSci. He has been called a "poster child" for patenting professionals. He is the owner of six companies and has more than 150 patents. He has sued companies such as Fujitsu and Alcatel-Lucent, Huawei and Nokia in the past using those patents.The University of Michigan employs Islam. Apple claimed that his patents are owned by the university. However, the University of Michigan supported Apple. Appeal court ruled that this was not true and that Islam's employment contract did not automatically transfer his patents to university.Omni MedSci claims that Apple willfully violated its patents. The company seeks an injunction to prevent the sale of Apple Watches, as well as damages. Omni MedSci's lawyer told Reuters that the company was "pleased but not surprised" at the ruling.
