General Mills‘ 6 February patent 6183788 titled ‘Flaked R-T-E cereal’ is a simple concept: curl the flake, so the flakes don’t remain flat on top of each other, and occupy more space than their flat counterparts. This lowers bulk density to <0.12, making them fluffy without any change in the flake per se.

Beginning from Kellog’s Patents from 1935 to 1940 as an individual, this field is currently dominated by General Mills and Quaker Oats.
