Apple will be halting sales of its Series 9 smartwatch, TechCrunch has confirmed. The news, shared by 9to5Mac, follows an October ruling by the International Trade Commission (ITC), owing to a patent dispute with California-based med tech firm, Masimo. The dispute stems from the blood sensor monitor on the latest flagship smart Watch.

The move goes into effect through online Apple Store at 3PM this Thursday (December 21), with retail locations ceasing sales December 24 – just ahead of the holiday.
