The Masimo trial ultimately failed to get a permanent ban on Apple Watch sales or use of the blood oxygen sensor, but the final verdict will have Apple pay $634M to Masimo’s new owner Danaher after the appeal was rejected.
Apple Watch users have been able to take advantage of the blood oxygen sensor in Apple Watch since a software update in January 2024 successfully bypassed a sales ban. Masimo’s attempts to reinstate a ban failed, and all that was left in the case for Apple to pay a fine.
Apple appealed the merits of the jury’s findings based on the definition of a “patient monitor.” According to a report from Law360, U.S. District Judge James V. Selna turned down Apple’s request.
That means Apple must pay the $634 million fine. There doesn’t appear to be any other path for appeal or recourse, as the judge rejected both requests for either a new judgement or trial.
Given the complexity of the United States legal system, don’t put it past Apple to find some other avenue for appeal. The money owed to Masimo is a paltry sum for the multi-trillion-dollar company, but Apple will always appeal where it can.
At least the lawyers got paid
In the end, Masimo didn’t succeed in getting the Apple Watch banned or fundamentally redesigned. It won an empty victory with the funds it will be paid, and the patents affecting the lawsuit will expire in 2028 and 2029 anyway.
Masimo isn’t a patent troll in the traditional sense of the word, as it does build products with its patents. However, it isn’t clear why the CEO pursued this lawsuit with such vehemence when the end result cost a lot of time and money.
As usual with these lawsuits, the real loser is the customer. At the least, it seems we may finally be able to put the Masimo saga to bed.
Masimo was purchased by the technology company Danaher on June 10, 2026 for $9.9 billion. It isn’t clear if the new parent company will care about the lawsuit or the patents in question.
That acquisition did tell us one thing — Danaher expects Masimo to generate EBITDA of more than $530 million in 2027. So, Apple’s $634M payment will be quite the boon for the new owners.
Time will tell if this Masimo case is somehow brought back from the dead.
