Zep Solar strengthened by US patent office action against Westinghouse Solar

SAN RAFAEL, USA: Zep Solar Inc., creator of the world’s first module-integrated PV installation platform, announced that the United States Patent and Trademark Office (USPTO) has sided with the company by issuing an Action Closing Prosecution, reaffirming the USPTO’s prior rejections of every claim in Westinghouse Solar’s patent #7,987,641 (the ‘641 patent).

Westinghouse had alleged in a complaint to the International Trade Commission (ITC) that Zep Solar was infringing its ‘641 patent. However, the USPTO has now reaffirmed that all of Westinghouse’s ‘641 patent claims are invalid.

“The recent action by the USPTO greatly strengthens Zep Solar’s position in the face of Westinghouse’s patent infringement allegations,” said Jack West, founder and CTO of Zep Solar. “This validates our assertion that the inventions described by the ‘641 patent were not invented by Westinghouse.”
