Shouldn't CDMA be out of patent?

  Probably, but they have a whole portfolio of related patents obtained at later dates.

    Sure. So use something cinformant to the original standard.

      Backwards compatibile with the old standard. But newer standards are very different. If you want to use the CDMA standard from 1995, you can do so without invalidating a patent. But nobody wants to do that.

  Qualcomm keeps making new IP that has contributed to newer standards like CDMA2000, UMTS & HSPA, and LTE. The article makes it seem like it's Qualcomm's "CDMA Technologies division" that's driving revenue. That might be what Qualcomm calls the division (or not), but it sounds like the division that makes its chips. Either way, Qualcomm still owns a lot of standards essential patents needed for running a modern wireless network or handset.
