so, are there essential WCDMA patents which expire soon? Since NOK and others in Euro were early in filing, does their patents also expire giving them less percentage of "essential patents"? Probably not. As the paper on the relative merits of WCDMA patents made clear, Q started filing patent claims well before WCDMA standardization whereas Nokia started filing patents as part of the standardization process. Does an improvement patent, one which is based on a previous patent, and adds to the functionality of it, thus extend the original patent due to it's citing? Forgotten the terminology, but there are two kinds of patents: a) Ones that clarify/extend the claims a previous patent and thus expire at the same time as the original. b) A completely new patent - with its own separate life.
