Apple is suing Motorola, saying that Motorola has infringed on patents related to its smartphones.
Apple said in a filing that the Droid, Cliq, BackFlip and other phones from Motorola violate its patents related to the iPhone’s touch screen and user interface.
Apple says it wants Motorola to stop using the patents and is seeking an unspecified amount of damages, as well as its lawyers’ fees and costs. The lawsuit was filed in a federal district court in Wisconsin on Friday.
The suit comes after Motorola sued Apple in October over patent infringement.
Motorola was a top cellphone maker in 2006, because of the popularity of its Razr clamshell phone, but it was surpassed by others when smartphones became popular. Meanwhile, iPhones from Apple have surged in popularity. The company sold 14.1 million last quarter.
Motorola is the seventh-largest phone maker in the world. In North America, it is outstripped by Apple and Research In Motion, the maker of the BlackBerry. Motorola’s recent smartphones, like the Droid line of phones, run on Google Android software.
