In an ongoing dispute between VirnetX Inc. vs. Apple Inc., Apple Inc. had challenged the validity of two asserted VirnetX patents (US Patent Nos. 6,502,135 and 7,490,151). Apple was initially unsuccessful in its IPR institution requests, because it was time barred under the IPR statute of limitations, which requires a PTAB IPR challenge to be brought within 1-year from the date that the complaint is served on the defendant. After several failed attempts, Apple Inc. recently circumvented the IPR statute of limitations, via 35 U.S.C. 315(c) joinder to another petitioner, The Mangrove Partners Master Fund, Ltd.
