US - China TRIPS dispute?

Thanks to the IPkat and Bloomberg for details of a possible complaint by the US against China to the WTO Dispute Settlement System, as a result of China's implementation of TRIPS.

We are very interested at the possible further use of the WTO fora in interpreting TRIPS and providing an alternative, or parallel, means of dispute resolution and development of IP jurisprudence. A clash of two such major powers, with huge interest in technology development and manufacturing, could reveal much of interest.
