Sales on the Apple Watch Ultra 2 and Apple Watch Series 9 were paused late last year due to a patent dispute with medical technology company Masimo. The International Trade Commission (ITC) ruled that the blood oxygen monitoring features on Apple's devices infringed on patents held by Masimo. Thus Apple pulled both watches from their shelves.
According to a statement by Masimo, those features will be dropped on the Apple Watch Ultra 2 and Series 9.
