I don't think it is over yet, per PTSC investor relations reponse:

We can confirm that the ITC has reported in its Investigative History as to Kyocera that the complaint has been withdrawn and the proceeding terminated. The conditions precipitating these events were accompanied by strict confidentiality provisions allowing us only to acknowledge what the ITC has already made public. Unfortunately we are unable to say or do more in regards to this matter. The company continues to expect an initial determination from the court for the remaining respondents by September 6th, 2013.
