Apple has filed a motion in a California court to prevent Samsung selling its latest smartphone, the Galaxy S III in the US, according to court papers.
The filing, made Tuesday in the California district court in San Jose, was posted online on Wednesday by Florian Mueller, a leading patent law blogger.
In the filing, Apple asked the court to add the new phone to its existing complaint against the Samsung Nexus, which the South Korean company developed in conjunction with Google.
"Apple has been able to obtain the Galaxy S III sold in the United Kingdom and determined that this device clearly infringes on at least two of the Apple patents at issues in the preliminary injunction motion for the exact same reasons as the Galaxy Nexus," Apple wrote in its filing.
Apple claimed that the new phone, which is yet to go on sale in the US, could cause it "irreparable harm," citing press reports that mobile companies had already sold more than nine million units in pre-orders.
