Oh OK, so it's not necessarily the same fee for everybody then?
Fees are probably negotiated individually, at least for larger licensors, but that's not exactly the issue.
I think it's like a percentage thing. So let's say you make a Star Trek product. Book, art print, model kit, soundtrack CD, whatever. You're supposed to give Paramount 10% of the revenue from each sale, so you sell one book for $10, they get $1. You sell one fine art print for $100, they get $10. The part that went up is that there's a certain baseline royalty they get no matter how much you sell. Let's say that's $1000. So if you're selling books, that means you need to sell 1,000 units to meet your obligation. If you sell more, great, but if you only sell 100, that means you've only given them $10, and need to pay them $90 out of your own pocket. If you're selling art prints, that means you need to sell just 100 units, but it's a more expensive specialty product, so you aren't going to sell as many as you are books, but if the minimum royalty is low enough, that doesn't matter.
Imagine Star Trek books move 10,000 copies (so Paramount gets $10,000), but Star Trek art prints only move 200 units (Paramount getting $2,000). That's fine, both cover the minimum licensing fee. But now Paramount has decided they want to make Star Trek licensing a little more exclusive, for whatever reason, so they've increased the minimum royalty to $5,000. That's still below what Star Trek books get them as a matter of course, so there's no change in practice for them, but that's more than double what the person making the art prints was paying. So they need to make up the difference out of pocket, figure out a way to increase production/sales to meet the new minimum, or drop the license.
