(1) Note. Disposition of yeast patents claimed or disclosed (a) as an edible, (b) as a component in an edible, or (c) as a single source material for producing protein useful in making an edible: (a) Yeast with a claimed or solely disclosed utility as a foodstuff in the form it is produced by a Class 435 process is classifiable in Class 426; (b) Yeast claimed or disclosed as a component of an edible is classifiable in Class 426 if the claim or disclosure is that the yeast is a food supplement and is not medicative (i.e., used to alleviate a disease) in which case placement in Class 424 is proper; (c) Refined or crude yeast protein is not classifiable in Class 426 solely on the basis of a Class 426 utility. Refined yeast protein is classifiable in Class 530. Crude yeast is usually disposed of on the basis of utility.
