Rebekah Vardy trademarked the phrase "Wagatha Christie" after losing her libel case against Coleen Rooney.
Vardy unsuccessfully sued Rooney at the High Court last year for claiming to have deduced that Vardy had been leaking stories about her to the press.
The case was dubbed Wagatha Christie - a reference to both women as wives and girlfriends (Wags) of footballers, and mystery author Agatha Christie.
Vardy didn't come up with the pun - comedian Dan Atkinson claimed he did.
The phrase was registered for trademark in the UK in August, through the company London Entertainment Inc Ltd, and it covers everything from broadcasting to beauty lotions, as well as jewellery, stationery and fashion design.
The move could go some way to paying Vardy's legal costs from the trial. In October, it was reported that she had been ordered to pay 90% of Rooney's legal fees, expected to equate to £1.5m.
