> Trademark is suppose to be about customer confusion, no one is confused here.
This is not a good take on the Supreme Court ruling, at all. I generally agree with your rhetoric about IP maximalism, but this is not the right case to trot it out for.
This case was not about whether anyone was confused. The ruling does not take a position on whether there was confusion between Bad Spaniels and Jack Daniels.
Instead, this ruling says that humor is not an absolute defense in trademark disputes. It reverses a Ninth Circuit ruling that held that, in the case of humor, the court does not need to even evaluate whether or not there was confusion.
This ruling sends the case back to the Ninth to evaluate the totality of the case, including fair use, parody, and whether the for-profit Bad Spaniels is appropriating Jack Daniels' trademarks to sell their products in a way that a reasonable person would think Jack Daniels was involved in.
The Ninth may very well find that no, there is no confusion, and the use of the trademark is indeed fair use. But they will have to consider that as a dimension of the dispute, where previously they ruled it was immaterial.
IANAL, and it's possible I've gotten some details wrong here, but IMO this is the right ruling. Just slapping a joke on an otherwise infringing product should not provide immunity from trademark claims.
