Patent holder Unwired Planet has filed suit against Apple and Google, accusing the firms of infringing on 20 of its patents.
In two separate complaints filed in Nevada, America, Unwired Planet said Google and Apple violated patents relating to smartphone devices, cloud computing, digital content stores, push notification technologies, and location-based services like mapping and advertising.
Unwired Planet shifted its focus to intellectual property last year, and has been working to license its portfolio of 200 patents, CEO Mike Mulica said in a statement. Or patent trolling, depending on who you ask.
"Apple and Google generate substantial revenues from devices and services that rely on the intellectual property that Unwired Planet developed and patented over the last 15 years," Mulica said. "They should compensate us for the use of our patented technologies, which are foundational to mobility."
A Google spokeswoman said the company has not been served, and therefore has no comment. Apple did not immediately respond to a request for comment.
The case against Apple alleges that the firm infringed with its mobile devices (iPhones, iPads, iPods), mobile digital content (Apple App Store, iTunes), cloud messaging (push notifications, Siri), and map and location systems (Apple Maps, local search, iAds, Safari browser, Find My iPhone).
Unwired Planet is still waiting on a verdict regarding four patents pending in a case filed last year against Apple and Research in Motion.
Some of Google's infringing products include search and advertising (Google search, Google+Local, Google Places), mobile digital content (Google Play), short-range radio communications (Google Wallet, Google Offers), and mobile devices (smartphone and tablets running the Android OS, including Motorola Mobility and Nexus products).
Unwired Planet is currently relocating to Nevada, since it has "developed specialized procedures to handle complex patent cases."
"As a result, we believe the Nevada district will be an ideal venue to resolve this matter with efficiency and expertise," Mulica said.
Apple is no stranger to patent infringement cases, having just prevailed in August against Samsung. This week, Samsung announced that it will likely go after Apple again, this time over the iPhone 5.
