In high school economics class, we had to invent a fake product, fill out patent applications, do focus groups, make a commercial and print ads, and do all the other stuff you'd normally do if you were a real company (except we submitted paperwork to the teacher, obviously, and not the USPTO).

My group's product was a weight-loss product called "FlavorAir" ("Anorexia Fast" didn't test well with our focus groups). It was literally this (except we used breath spray as our product prop in the commercial we made).

My group may also hold "prior art" for flavored vapes, lol, depending on how vague those are interpreted.
