Did Panasonic actually design the new Leica Q3 43 lens?

Asobinet spotted this Panasonic patent that describes the optical design of a full-frame lens that appears to be exactly the same as the new Leica Q3 43mm camera. Panasonic is well known for making some Leica cameras (SL and Q series). I did not expect this lens to be made by Panasonic as well.
