Apple has once again been banned from selling two smartwatch models in the US, while a legal battle continues over a patent dispute.
The tech giant was earlier allowed to sell its Series 9 and Ultra 2 watches while proceedings were ongoing – but a US appeals court has since reversed that decision.
Imports of watches are also affected.
On Thursday, Apple said it will release watches without the disputed blood oxygen feature to keep them on shelves.
It is the latest turn in a dispute between the firm and medical technology company Masimo.
Masimo and spin-off Cercacor have accused the iPhone maker of poaching key staff and taking other steps to steal technology it developed to measure oxygen levels in the blood.
In October, the US International Trade Commission said it agreed that Apple had violated some patent rights and issued an order barring certain imports and sales. This had been due to go into effect in late December but was paused while the appeal was underway.
