GIF-Entwicklungsgesellschaft mbH

Patent Legal Situation

The developments of GIF-E, especially the Cone-Ring-Transmission and Axial Piston Engine, are covered worldwide by more than 500 patents and therefore are fully protected. Our accompanying patent research has shown that there are no comparable activities worldwide, thus, GIF-E has a great technological advantage. This advantage will continue due to the patents for a long time.

Throughout different patent families, the Axial Piston Engine for example is protected through the patents of the 2-stage combustion chamber, the combustion chamber control and the ceramic lining of the combustion chamber.


Patents have been carried out in the USA, Japan, China, Korea, India, Russia, Brazil and Europe.
