Apple has filed a patent infringement suit against Motorola.
The lawsuit alleges that Motorola is illegally using Apple's patented multi-touch technology in the Droid X and Droid 2 Android-based smartphones.
The patent infringement suit is in response to Motorola suing the iPod maker for infringing upon 18 Motorola patents and asking the courts to ban Apple from selling the offending products in the US.
Motorola has also appealed to the court to invalidate Apple's multi-touch patents as the technology has already become an industry standard.
According to court documents, Apple claims that Motorola infringes on 6 Apple patents related to the multi-touch technology used in Motorola smartphones, user interface and installed software applications.
Apple has also named the Verizon Droid 2 and Droid X, the Backflip, Charm, Cliq, Cliq XT, Devour and the i1 as devices that infringe upon the patents, tech news site Patently Apple reports.
The Cupertino-based consumer electronics giant has said that it is seeking the maximum amount of damages from the case, including all royalties from every offending phone sold.
