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"? One more thought. 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? Can that improvment patent thus stand on it's own merits or can someone replace a simliar patent under the improvment patent which would tend to create a new foundation?
