Kim Kardashian and her family just dropped the hammer on a plastic surgeon who's been cashing in with something called the "Kardashian Facelift."
According to docs obtained by TMZ ... the Kardashians sicced their attorney on Dr. Gary Eldridge, demanding he quit using their name to promote his product, or else.
But the letter to Dr. Eldridge informs him the family already holds countless trademarks on its name for beauty, cosmetics and all sorts of advertising, upon which he is infringing.
In plain English: Beat it, doc ... we're working this corner!
The doc got the message. He's already dropped his trademark application and removed "Kardashian" from his website. His patients now have to get a plain old "Fibrin Facelift."
