Kardashian family 'threaten legal action against surgeon for using their name to promote facelifts'... but he claims it's also the name of his DOG

They are one of the most entrepreneurial families in the world and have used their globally recognised name to front a string of business ventures.

And the Kardashian clan are making it clear that they will not take lightly to others attempting to cash in on their famous moniker and have reportedly gone down hard on a plastic surgeon who has been offering his patients what he has dubbed the 'Kardashian Facelift'.

According to documents obtained by TMZ, the Kardashians have had their attorney hound Dr. Gary Eldridge and demand that he quit using their name to promote his fibrin protein treatment. 

They're definitely Keeping Up! The Kardashian family are making it clear that they will not take lightly to others attempting to cash in on their famous moniker and have reportedly gone down hard on a plastic surgeon who has been offering his patients what he has dubbed the 'Kardashian Facelift'

In an attempt to fight his corner, the Australian doctor has filed documents to trademark the procedure in the U.S.

It's alleged the surgeon has insisted that the treatment is not at all connected with the famous family and is actually the name of his family dog.

Unsurprisingly, the Kardashian's lawyer reportedly refused to accept the doctor's claim and informed him in a very affirmative letter that the family already holds countless trademarks on its name, in all matter of fields, from beauty to advertisements, which Dr. Eldridge is infringing upon.

It's believed the surgeon has since dropped his trademark application and has removed the Kardashian name from his procedure, instead calling it simply a 'Fibrin Facelift'.
