Aviation Partners Fights Back Against Airbus Lawsuit

Aviation Partners filed a response yesterday to Airbus’s pre-emptive lawsuit that seeks to invalidate an Aviation Partners patent for blended winglets. This patent–filed on Feb. 1, 1993, and granted Sept. 20, 1994–is for technology that is the foundation of the Seattle-based company. Since patents perish after 20 years, this one will expire in about 12 months.
