The former world No 1, who is the richest female athlete in the world, has asked Florida's Supreme Court to push through her request on the understanding her name will revert back after the tournament.
The 26-year-old spent more than £300,000 setting up Sugarpova, a brand featuring brightly coloured sweets with such flavours as Smitten Sour, Quirky and Sporty.

It is estimated that almost 2 million bags of the sweets were sold last year, topping up Sharapova's yearly earnings to £15million.
The Russian may still need the permission of the grand slam committee but if that is granted, she could be introduced and addressed as Miss Sugarpova. Scores would also be read out in favour of her new moniker.
The news follows confirmation that Sharapova has split with coach Jimmy Connors after just one match.

Connors' only previous coaching role was with Andy Roddick in 2006 for 18 months, and it was a rather lean period in the career of the huge-serving American.
It means Sharapova is expected to go to the US Open without a coach.
The 2004 Wimbledon champion has won two tournaments this season, in Indian Wells and Stuttgart, but lost in the final of the French Open to Serena Williams who has beaten her the last 13 times the pair have met.
