The 24-year-old winger, who scored 21 goals in the Premier League last season, is priced at £100 million amid heavy interest from Real Madrid
The Wales international, who is valued at £100 million by Spurs in the wake of Real Madrid's intense interest, is now able to use the celebration on "clothing, footwear and headgear" as well as precious metals and leather.
Bale regularly forms a heart shape with his hands after scoring a goal - something which he managed to do 21 times in the Premier League last season.
Should Bale make the move to Spain, his global appeal would likely rocket, especially if a world-record fee, widely expected to be involved in the deal, is parted with for his services.
His recently trademarked celebration could be a big part of Bale's image rights and add to the wages that Madrid could offer him. No player at Madrid currently wears Bale's number 11 shirt.
Bale, 24, won both the PFA Player and Young Player of the Year awards last season as Tottenham finished fifth.
