Another day, another lawsuit. Unwired Planet, through its Nevada-based subsidiary, Unwired Planet LLC, has filed patent infringement complaints against Apple and Google in the U.S. District Court for the District of Nevada. The suits involve … you guessed it … patent infringement.

In two separate complaints filed in Reno, Nevada, Unwired Planet — which calls itself ” “the inventor of the mobile Internet” — charges Apple with infringing 10 of its patents, and charges Google with infringing 10 different patents. Together, the two cases charge infringement of a total of 20 patents related to smart mobile devices, cloud computing, digital content stores, push notification technologies and location-based services such as mapping and advertising.

In the case against Apple, the complaint specifically alleges that infringing Apple products and services include, among others:

° Mobile devices (including mobile phones, tablets, and music players with the iOS operating system including iPhones, iPads, and iPods);

° Mobile digital content systems and/or services (including the Apple App Store, Apple apps, iTunes);

° Cloud messaging systems and/or services (including Apple’s Push Notification Service, Siri);

° Map and location systems and/or services (including Apple Maps, Local Search, iAds, Safari web browser, Find My iPhone, Find My iPad, and Find My Friends).
