PCTEL Requests Re-exam of Interference Detection Patent

PCTEL, Inc. (NASDAQ: PCTI), a leader in propagation and optimization solutions for the wireless industry, announced today that it had requested the U.S. Patent and Trademark Office to re-examine and reject all of the claims in patent 7,301,920 (Sanders, et al.). PCTEL has submitted extensive documentation demonstrating that the inventor misled the patent examiner by failing to disclose certain relevant PCTEL patents as well as other earlier patents of the inventor. PCTEL has argued that all of the ‘920 claims should be rejected on the grounds that those claims are based upon earlier, patented work.

In August, 2008 the USPTO rejected all 13 claims of another interference detection patent 6,754,487 issued to the same inventor.

"Since 2001, PCTEL has been vigilant and aggressive in protecting its intellectual property,” said Marty Singer, PCTEL’s Chairman and CEO. "We will pursue any company that develops and sells a product that infringes our core interference detection technology on which our Clarify^® products are based. The rejection of these patent claims will make that clear,” added Singer.
