Hanger Solutions, LLC is one of several Georgia entities associated with Atlanta-based monetization firm IPInvestments Group LLC (d/b/a IPinvestments Group) to have collectively acquired thousands of patent assets from Intellectual Ventures LLC (IV) in late 2019. Those portfolios have spawned multiple litigation campaigns since, now including a case filed directly by Hanger, which earlier this month sued Extreme Networks (1:21-cv-00040) in the District of Delaware over three of its acquired assets. The NPE targets Extreme for its provision of the Extreme Cloud network management platform and Extreme Networks SLX-series switches.
