I don't know that I or anyone other than EBI themselves, know the details of their licensing agreements. A standard licensing fee business model usually includes a global fee for the use of the name itself, plus perhaps an additional fee per unit sold.
If their model includes a "per unit sold", then change, color, new innovation applies.
Maybe some EBI company representative in the know can comment. I doubt it, as their licensing agreements are most likely confidential. Maybe not?
