Apple has asked a court in California to block the sale of the new Samsung Galaxy Nexus smartphone in the US, according to Reuters.
This is the latest move in an escalating patent war between the two companies being fought in Europe, Australia and the USA.
Apple has alleged that the new Galaxy Nexus smartphones, which use Google's newest version of Android called Ice Cream Sandwich, violate four Apple patents, including new features such as a voice-command search function.
The phone is the first to run on the newest Android version before the platform is adopted by hardware manufacturers such as HTC Corp and Motorola Mobility.
HTC and Motorola are also fighting patent battles with Apple.
In the Apple lawsuit, filed last week in San Jose, the company has said that the Galaxy Nexus infringes on patents underlying Apple product features, including the ability to unlock phones by sliding an image and search for information by voice.
Samsung said in a statement on Monday that it knows of the filing by Apple in the California court.
"We continue to assert our intellectual property rights and defend against Apple's claims to ensure our continued innovation and growth in the mobile communications business," Samsung said in the statement.
Apple and Samsung are currently waging more than 20 legal fights in at least 10 countries in their war for global leadership of smartphone and tablet markets.
