Dana Point, California. Mercury Cable (www.mercurycable.com), the leading developer of High Voltage Composite Reinforced Conductors (“HVCRC®”) for electrical transmission lines, is pleased to announce that, in a patent opposition proceeding in the European Patent Office (EPO), Mercury Cable and Epsilon Composite invalidated all claims of the European ACCC patent of CTC Global1. The invalidation of all ACCC patent claims resulted in the complete revocation of the ACCC patent in Europe, as stated in the minutes of the proceeding published by the Chairman on July 3rd, 2019.
The revocation decision is available online at:
CTC Global filed an appeal of the revocation decision to the Board of Appeal, and, after receiving the Board of Appeal’s preliminary opinion which considered that “the appeal at hand does not appear to have prospect of success,” CTC Global withdrew the appeal and the ongoing court actions in France. The decision to revoke CTC Global’s European Patent EP1506085 is now final. It applies to all countries that this European ACCC patent covered.
