Here are some links that reports on Neustar licensing with Neomedia and once again, you are talking about one patent, 048, however, you are linking all of NeoMedias's patents in your previous statement below.
Considering Neustar has relicensing rights, there could never be exclusive rights to NeoMedia's patents ever again.
Additionally, the Microsoft license restricts NeoMedia's ability to transfer, sell, or re-assign those patent rights. They can never sell the patents.
