Patent-holding giant Intellectual Ventures (IV) began enforcing some of its massive stash of patents with lawsuits in 2010. But its first case, against Motorola Mobility, ended in a mistrial last year when a jury couldn’t agree on the outcome.
Now that case is teed up again with a different set of patents. IV is claiming that Motorola products infringe patents 7,810,144, “File transfer system for direct transfer between computers,” and US Patent No. 7,409,450, which describes a system of “packet-centric wireless point to multi-point.” Neither of these patents were in last year’s trial, although they were mentioned in the original complaint (PDF).
A third patent, 7,120,462, has a priority date of 1999 and describes a portable computer with a detachable handset. The ‘462 patent, invented by Rajendra Kumar, was in last year’s trial and will feature again. IV claims Motorola used this patent in its defunct Lapdock product.
