Mike Lin filed a trademark for “Nasty Woman” on October 20th — the day after the debate — and immediately began selling t-shirts on his online store. Problem is … Lin tells TMZ many folks on Etsy and other sites have been selling their own “Nasty Woman” tees — so he’s gotta go after ’em.
Check out the vid … Lin says he’s spent thousands on trademarks over the years, and it’s his right to defend them — just like brands like Kleenex would.
He may be in for a long battle, though … a trademark isn’t officially protected until it’s registered — which could take up to a year.
