Samsung has failed to halt an injunction blocking US sales of its Galaxy Tab 10.1 tablet.
The ruling is the latest episode in an ongoing legal war between Samsung and Apple, with both companies having mounted litigation against the other accusing them of copyright infringement.
The sales ban was put in place after Apple convinced the court that there was sufficient merit in its claims of patent abuse to award a temporary ban.
Apple was ordered to post a $2.6m bond to protect Samsung from damages in the event that the patent claims were dismissed.
As well as its ban on the Galaxy Tab 10.1 Apple also secured a similar sales ban blocking the sale of Samsung's Galaxy Nexus smartphone. The ban was put in place by a San Francisco court on 29 June, after the iPhone maker accused the Galaxy Nexus of infringing on four of its patents.
Apple was required to post a $95m bond designed to cover possible losses by Samsung should Apple's claim be overturned.
The lawsuits have led to a patent accumulation battle between the two companies, with both looking bolster their legal defences by improving their patent portfolio.
Most recently Samsung purchased British chip maker CSR's mobile phone connectivity and location technology for $310m, in a move that will bolster its patent portfolio.
