Many thanks for the rundown on the patent litigation. I don't know of any more complete assembly than what you have provided. Very much appreciate. One of the key patents, called 5,103,459, deals with the essential features of CDMA. My impression was that this earlier patent was part of a cross licensing agreement with Motorola, in return for certain patents Motorola had, which QCOM needed. It is also the patent that Ericsson challenged, which produced a comment from the judge that he thought QCOM would prevail.

I understand that the latest litigation concerns what QCOM interprets as a breach of earlier agreements, thereby giving QCOM the right to void its agreements with Motorola and charge MOT with patent infringement as a result. I'm not a lawyer, so I can't be sure whether this is exactly what is involved. Given the number of challenges to QCOM's CDMA patents, and the fact that most of the issues have been resolved in favor of QCOM, I'd say that QCOM remains in a pretty controlling position.
