Apple's $634M payment to Masimo now set in stone after Judge tosses appeal - AppleInsider

What the report says

AppleInsider reported that Apple’s $634 million liability in its long-running dispute with Masimo has effectively been upheld after U.S. District Judge James V. Selna rejected Apple’s post-verdict challenge. Citing a Law360 report, the outlet said Apple had contested the jury’s findings over the meaning of a “patient monitor,” but the judge denied Apple’s requests for either a different judgment or a new trial.

The case centered on Apple Watch blood-oxygen technology and Masimo’s claims tied to its monitoring patents. According to AppleInsider, Masimo did not ultimately secure a permanent ban on Apple Watch sales or on use of the blood oxygen feature. Apple Watch users have continued to have access to the sensor after Apple issued a January 2024 software update that the article says avoided a sales ban.

AppleInsider said the rejected appeal leaves Apple required to pay $634 million to Masimo, now owned by Danaher. The article noted that Danaher acquired Masimo on June 10, 2026, for $9.9 billion, and said Danaher has projected Masimo will generate more than $530 million in EBITDA in 2027. The publisher characterized the payment as financially manageable for Apple but still significant for Masimo’s new parent company.

The decision matters because it appears to narrow the legal path for Apple in a dispute that has affected one of the Apple Watch’s health features. AppleInsider cautioned, however, that Apple could still look for another legal avenue given the complexity of U.S. litigation.
