[V]irnetX, Inc. v. Apple Inc. et al.
On August 11, 2010, VirnetX, Inc. filed an action against the Company alleging that certain of its products infringed on four patents relating to network communications technology. On November 6, 2012, a jury returned a verdict against the Company, and awarded damages of $368 million. The Company is challenging the verdict, believes it has valid defenses and has not recorded a loss accrual at this time."
Another fact; New Bay and RPX, back by Apple were shot down by the courts. Their goal to invalidate VHCs patents that were validated both in federal court and by the US patent office. Last ditch effort by Apple and now moments away from the jury verdict being upheld by the federal appeals court.
