(Zep Solar), creator of the world's first module-integrated PV installation platform, today 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).
