Apple has filed another lawsuit against Motorola over smartphone technologies.
The iPhone maker claims that Motorola’s Droid phone maker infringes on three patents covering touchscreen software and other display technologies.
“Motorola’s infringing activities have caused and will continue to cause Apple irreparable harm, for which it has no adequate remedy at law, unless Motorola’s infringing activities are enjoined,” Apple said in a nine-page filing on Friday with the US District Court for the Western District of Wisconsin.
Motorola said it has not yet reviewed Apple’s filing, but said it will “vigorously defend” itself.
The suit is a latest in a series of legal salvos between the two companies, which were once close allies. Last month Motorola sued Apple in Delaware court earlier this month, asking a judge to declare it is not infringing on a dozen Apple software patents, in response to an earlier complaint by Apple.
Apple is also embroiled in legal disputes with HTC, Nokia and Kodak over phone technologies.
