Patent war goes nuclear: Microsoft, Apple-owned “Rockstar” sues Google | Ars Technica

The ghost of Nortel is activated by Microsoft, Apple, RIM, Ericsson, and Sony (collectively "Rockstar Bidco")

"Rockstar may want to keep the patent conflict as a kind of "proxy war" between Google and its competitors. But Google has plenty of patents, and this new attack seems assured to bring a counter-attack.
The smartphone market is more valuable than ever, and the $4.5 billion Rockstar purchase shows that Google's competitors will spare no expense to put a damper on Android, and they hope to make money while they do it. Patents have become the arena in which tech companies have chosen to do battle. Six years after the iPhone and five years after the launch of Android, the stakes keep getting raised."
