US EditionITC judge says Apple Watch's redesigned blood oxygen feature doesn't infringe Masimo patents
Apple’s redesign moves blood oxygen processing to iPhone, avoiding patent infringement while the original feature remains banned under a 2023 ITC exclusion order.
- On Wednesday, ITC Administrative Law Judge Monica Bhattacharyya wrote that there is "no underlying act of direct infringement" on Masimo patents by the redesigned version of Apple Watch's blood oxygen feature.
- Apple redesigned the blood oxygen feature in August 2025, moving data processing to the iPhone after a 2023 import ban forced the company to briefly pause sales and disable the sensor.
- Separately, the United States Court of Appeals for the Federal Circuit affirmed the original 2023 ITC exclusion order, meaning the original version of the Apple Watch blood oxygen feature remains banned.
- A federal jury previously awarded Masimo $634 million, which Apple is appealing; the company stated it is "evaluating all avenues for further review" regarding the ITC decision.
- The ruling from Judge Bhattacharyya now goes to the full ITC Commission as an initial determination for a final decision on whether to affirm the findings.
