If I’m understanding correctly it’s a “flat rate royalty”, ie: not 5% or 0.5% or whatever but rather is specified in a fixed “$ per units sold”.

It doesn’t seem like it rises with inflation, so it’s value in real terms will decline over time if Listerine’s sales volume remains constant.

This will be particularly noticeable during periods of high inflation, which is probably why it’s on the market right now!
