There was a radio show on Trade Marks, Copyrights, and Pattens. I called in
an asked about "TM" and "R" on recipes.
He said you (Trade Mark) "TM", or "R" register, a recipe to protect you in
selling an identified product in your bussiness. TM covers you on the state
level, and "R" like on Red Lobsters "Alotta Colada" covers you on the federal
level. You copyright the name and the ingredients.
