VirnetX Holding Corp., an Internet security software and technology company, says the United States Patent and Trademark Office (USPTO) has denied seven petitions for inter partes review (IPR) filed by Apple.
These petitions sought review of certain claims of VirnetX's U.S. Patent Nos. 6,502,135, 7,418,504, 7,490,151 and 7,921,211. The USPTO found that Apple's petitions weren't filed within the time limit imposed by the statute and declined to institute inter partes review.
