I am not sure of the current status of CWE's collaboration with EDF. Previously EDF were the northern hemishere licencees for Ceto technology, that may still be the case.

I remember reading somewhere not long ago, (probably an annual report), that the full resources of EDF were being used to protect Ceto IP.

EDF being one of the world's biggest energy companies, would have the ability to protect IP at the highest level.

I haven't read anywhere that CWE's ties with EDF have ceased.
