Apple Inc. is accused of stealing trade secrets and improperly using Masimo Corp. inventions related to health monitoring in its Apple Watch.
Masimo, which develops signal processing technology for health-care monitors, and its spinoff, Cercacor Laboratories Inc., claim in a lawsuit that Apple got secret information under the guise of a working relationship and then hired away key employees, including Michael O’Reilly, who became vice president of Apple’s health technology efforts.
