Google isn't about to remain idle while the Apple- and Microsoft-led "Rockstar" patent group sues numerous Android partners. The search giant has quietly filed a declaratory judgment complaint asking a San Jose court to rule that the company (and therefore, the Android ecosystem) doesn't infringe seven of Rockstar's patents. As GigaOM notes, Google isn't mincing words -- the firm accuses Rockstar of "placing a cloud" over Android and harassing a large part of the technology industry. The legal action doesn't necessarily amount to fighting fire with fire, though. Declaratory judgment complaints frequently represent attempts to score an early victory, rather than the first line of defense; Google likely has more up its sleeve if this tactic doesn't work.
