The US is set to ban some older Samsung phones and tablets in the latest round of patent battles between the South Korean firm and US rival Apple.
In August, the US International Trade Commission (ITC) found Samsung had infringed two Apple patents on mobile technology, but cleared the firm of violating four others.
Apple called for a US ban on patent-infringing products, but the ban was postponed pending an appeal by Samsung.
The ban now looks set to go ahead after the US trade official overseeing the patent row rejected Samsung’s appeal, but it is unclear which products will be banned, according to the BBC.
Apple won a key victory just over a year ago when a US court imposed a $1bn fine on Samsung for copying key elements of the iPhone.
