From Heizer Defense’s press release …
In a continued effort to protect their product development and engineering efforts, Heizer Defense, LLC has filed a complaint in the United States District Court for ten counts.
This includes declaration of inventorship and transfer of rights for patent No 8,495,831 and for the declaration of invalidity and unenforceability, or alternatively correction of inventorship and transfer of rights for design patent No. D686,685.
We would expect the lawsuit to establish, among other things, that Charles Heizer, Founder of Heizer Aerospace, is an inventor for this patent.
The defendants of the complaint are Doubletap Defense LLC, f/k/a Heizer Technologies, LLC; Central Holding Corp.; Raymond Kohout, and Marvin Dufner.
The parties have agreed to mediation that is scheduled to take place in November.
