USPTO denies RPX petitions for VirnetX patent review

VirnetX Holding Corp. (NYSE: VHC) said that on June 5, 2014 the United States Patent and Trademark Office (USPTO) denied all seven petitions for inter partes review filed by RPX.

These petitions sought review of certain claims of VirnetX´s US Patent Nos. 6,502,135, 7,418,504, 7,490,151 and 7,921,211. The USPTO found that Apple is an unlisted real party-in interest in all the petitions filed by RPX and the Petitions were not filed within the time limit imposed by the applicable statute. The USPTO thereby declined to institute inter partes reviews of the challenged patents.

“We are pleased with the USPTO´s decision denying RPX´s petitions,” said Kendall Larsen, VirnetX CEO and president. “We continue to believe in the validity of our patents.”

VirnetX Holding Corp. is an Internet security software and technology company with patented technology for secure communications including 4G LTE security. The company´s patent portfolio includes over 80 US and international patents with over 100 pending applications. For more information, visit
