# 337-TA-1276 (itc)

Masimo's Section 337 complaint at the ITC over light-based pulse-oximetry. The Commission found the Apple Watch infringed claims 24 and 30 of Masimo US 10,945,648 and issued a limited exclusion order, leading Apple to disable the blood-oxygen feature on imported Series 9 / Ultra 2 watches. The ITC awards exclusion, not money damages.
