Irvine, Calif., May 7, 2012

CTC GLOBAL today announced that the United States Patent and Trademark Office (USPTO) has reexamined and upheld substantially all claims on three patents relating to its innovative composite core and conductor technology (U.S. patent numbers 7,368,162; 7,211,319; and 7,179,522).

The USPTO has now considered the validity of CTC GLOBAL’s patents on three occasions. After reviewing all of the submissions of potential prior art, a total of 175 claims across the three challenged patents were upheld or added as patentable.

This latest confirmation of CTC GLOBAL’s pioneering ACCC® composite conductor and core patents underscores the technology that CTC GLOBAL pioneered through 10 years of research and development and has proven in the field over the last eight years of commercial projects. As a result of this continual effort, CTC GLOBAL is the leader in composite-based conductor technology with 10 U.S. patents, 5 pending U.S. patent applications and over 200 international patents and patent applications.
