Nokia has just announced that it is commencing patent litigation against HTC, Research in Motion and Viewsonic in the US and Germany. It's claiming that a number of its patents are being infringed and has registered complaints with the ITC and courts in Delaware, Dusseldorf, Munich and Mannheim. Espoo's legal chief Louise Pentland has said that while the company currently licenses its FRAND patents to "more than 40 companies," it had no choice but to lay some courtroom smack-down on the named offenders. It appears that after losing its global market share crown and billion-dollar losses, the company is finally going on the offensive with its deep patent portfolio. You can judge that for yourself when you read the official line after the break.
Update: We've received some clarification from Nokia on what exactly is on the docket here. "Four of the patents asserted against Viewsonic in Mannheim are standards essential. The rest against Viewsonic and all against HTC and RIM are implementation patents, not declared essential to any standard and so we have no obligation to grant licenses."
