Transfer Portal Trademarked?

Anyone heard anything about this? Sounds pretty bizarre. Also sounds like it is a filing against Arkansas specifically but if so that is unclear to me.

Lawyer’s doing what Lawyer’s do. . . . with all due respect to the Razorback lawyers on the board here.

That made me weary just reading it

Should be against the law for professional wrasslers to call themselves wrestlers. They should be members of a union that represents stunt actors. What they do is not a sport.

I’m no intellectual property lawyer, but as I understand it, you can’t trademark a term already in widespread use. Words like Thermos ™ and Styrofoam ™ were trademarked before they were widely used. Is it too late to trademark “transfer portal” or even “portal king?”
