VirnetX has won another battle in its patent lawsuit with Apple, convincing the U.S. Court of Appeals to vacate and remand decisions by the US Patent Office's Trial and Appeal Board that invalidated two patents, reports AppleInsider. The new ruling may increase VirnetX — which I consider a patent troll — more leverage in receiving the $439 million the courts declared Apple owed.
Earlier this month, the Federal Court says the Patent Trial and Appeal Board largely “got it right” when it rejected several dozen VirnetX patent claims as anticipated or obvious. The Appeals Court obviously disgrees. VirnetX sued Apple in 2011, alleging that Apple products, including products containing the redesigned VPN On Demand and Per App VPN features implemented in Apple’s iOS 7, infringe VirnetX’s patented inventions. For the past nine years, the battle has ping-ponged from court to court with varying results.
By the way, a patent troll is an individual or an organization that purchases and holds patents for unscrupulous purposes such as stifling competition or launching patent infringement suits. In legal terms, a patent troll is a type of non-practicing entity: someone who holds a patent but is not involved in the design or manufacture of any product or process associated with that patent.
