Apple had said that a proposed redesign would allow it to circumvent findings that the watches infringe Masimo's blood-oxygen reading pulse oximetry patents.
According to Masimo's filing on Monday with the Federal Circuit, Apple told the U.S. Customs and Border Protection agency that its redesigned watches "definitively do not contain pulse oximetry functionality."
Irvine, California-based Masimo has accused Apple of hiring away its employees and stealing its pulse oximetry technology to use in Apple Watches after discussing a potential collaboration.
Apple has included a pulse oximeter feature in smartwatches since its Series 6 Apple Watch in 2020.
Masimo asked the ITC in 2021 to bar Apple's imports and sales of Apple Watches that allegedly infringed its patents.
