Masimo has also accused Apple of infringing on patents protecting its blood oxygen-sensing technology. The trial will last 10 days, and may feature testimony from Apple CEO Tim Cook.
Masimo scored a win against Apple in January, when a judge with the International Trade Commission ruled that Apple infringed upon Masimo’s pulse oximeter patents.
Masimo’s ultimate goal is an import ban on Apple Watches with pulse oximeter sensors. The ITC may finish its investigation into the case later this month. Apple has also been challenged by device company AliveCor, which successfully prompted the ITC to issue an import ban in December. But that ban is suspended until the two companies resolve their patent issues. The ITC has ruled in AliveCor’s favor, but the Patent and Trademark Office has come down on Apple’s side.
