The particular patent mentioned by i_q isn't used in either CDMA2000 or WCDMA. There is a lot of patent chaf out there with a lot of different contributions from a lot of different players....it's gona take a while to see where any/all the intersection points (infringment) are with our IPR.
IMO, we only have a very small part of "air interface"...
Not being a techie, I can't really tell what is happening with these patents. Is IDCC building on their established patents (I see one to do with TDD handover) or moving into new areas? Are other companies creating patents that build on or supplement IDCC's patents? Are their companies who have patents on processes that compete directly with our patent, especially our most important patent area, air interface?
