A court has banned sales of Samsung's Galaxy Tab 10.1 tablet in the US while it decides on the firm's patent dispute with Apple.
Apple has claimed that Samsung infringed its design patent and copied the look of its popular device, the iPad.
The Samsung tablet is considered by most analysts as the biggest rival to Apple's iPad.
The trial for the case is scheduled to begin in California on 30 July.
"Although Samsung has a right to compete, it does not have a right to compete unfairly, by flooding the market with infringing products," said US District Judge Lucy Koh.
In an emailed statement to the BBC, Samsung said that it "will take necessary legal steps" and that the ruling was unlikely to have a significant impact on its business.
Apple and Samsung are two of the biggest manufacturers of tablet PCs and smartphones.
The two rivals are involved in a variety of legal cases in various countries across the globe amid claims and counter claims of patent infringement.
While Apple had accused Samsung of copying its design and look, the South Korean firm has alleged that Apple infringed its patents relating to the way phones and tablet PCs connect to the internet.
However, this is the first time that either of the firms has been able to win an injunction banning sales of the rival's product.
