Google has decided to fight back against the Apple and Microsoft-backed patent troll Rockstar. It has filed a lawsuit, asking the court to state that the Android platform does not infringe any of the patents the patent troll is asserting against Android, Google, and Android OEMs. Google describes Rockstar's trolling in no uncertain terms.
Rockstar produces no products and practices no patents. Instead, Rockstar employs a staff of engineers in Ontario, Canada, who examine other companies' successful products to find anything that Rockstar might use to demand and extract licenses to its patents under threat of litigation.
A very interesting tidbit is found further down in the legal documents - Google claims that Rockstar actually contacted companies that use Android, asking them to... Stop using Android.
On information and belief, Rockstar contacted and met with these California-based companies in order to discourage them from continuing to use Google's Android platform in their devices, and to interfere with Google's business relationships.
This Apple and Microsoft shell company is way, way dirtier than we already knew.
