Network-1 Security Solutions, Inc. (“Network-1”) (OTC BB: NSSI) announced today that the United States Patent and Trademark Office (USPTO), in response to a third party request, agreed to reexamine the Company’s Remote Power Patent, U.S. Patent 6,218,930. This initial reexamination grant is no surprise as the majority of reexamination requests made to the United States Patent Office are granted. Requesting a reexamination is a typical move by defendants in the context of patent litigation.

“We proceeded to license and, where necessary, enforce our Remote Power Patent, anticipating such a reexamination proceeding,” said Corey M. Horowitz, Chairman and CEO of Network-1. “We’re presently in our third litigation and have been successful in the previous two. We will use this reexamination proceeding as an opportunity to confirm the validity of our Remote Power Patent that was already examined by the Patent Office in 2001 when all of its claims were found valid and patentable.”

The Company welcomes this reexamination and believes that the proceeding will further validate and strengthen its Remote Power Patent. As previously disclosed, should the USPTO or a court reach a final determination that the Remote Power Patent is invalid, such a determination would have a material adverse effect on Network-1 as its current revenue from operations depend upon the continued validity of the Remote Power Patent.
