Apple sued medical technology company Masimo Corp in Delaware federal court on Thursday, accusing its new W1 line of smartwatches of infringing several Apple Watch patents, reports Reuters.
The two lawsuits said Masimo copied Apple’s technology while seeking bans on sales and imports of Apple Watches in earlier intellectual-property cases against the tech giant in California and at a U.S. trade tribunal. Apple said Masimo “carefully studied Apple’s IP” during those cases and claimed a Masimo spinoff received confidential information about the Apple Watch.
In June Masimo filed a patent infringement complaint agains the tech giant and is asking for a ban on impacts of the Apple Watch. The medial device companyclaims that the Apple Watch Series 6 infringes on five of its patents for devices that use light transmitted through the body to measure oxygen levels in the blood. The company says that the tech is vial to its business and that Apple is unfairly copying its features.
In September 2020 Masimo accused Apple of trying to delay a legal fight over allegedly stolen blood-oxygen monitoring technology in the Apple Watch Series 6 so it could gain a more dominant share of the smartwatch market. Blood-oxygen monitoring is a key feature of the latest Apple smartwatch.
Masimo and its spinoff Cercacor Laboratories first sued in January 2020. They accused Apple of promising a working relationship only to steal secret information. The tech giant also allegedly attempted to hire away key employees, including Cercacor’s former chief technology officer and Masimo’s chief medical officer.
Masimo is an American manufacturer of noninvasive patient monitoring technologies based in Irvine, California. The company sells more pulse oximetry to hospitals than any other company.
