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 45 of its standard-essential 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 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.
