The Apple Watch violates patents owned by California-based Masimo, the US International Trade Commission (ITC) ruled on Thursday [PDF]. The federal agency issued a limited exclusion order for the smartwatches, meaning the Apple Watch is in jeopardy of an import ban.
The ITC's ruling upholds a January ruling that found that the Apple Watch infringed on a Masimo patent. The exclusion period recommended on Thursday is supposed to go into effect after 60 days, during which time President Joe Biden can overturn the ruling. Biden previously declined to veto an ITC ruling that found the Apple Watch violated patents of a different company, AliveCor.
The debate is over Masimo's light-based pulse oximetry. The ITC's ruling doesn't specify which watches are affected. But the first Apple Watch to feature blood oxygen monitoring was the Apple Watch Series 6, which came out in 2020.
