Pop superstar Lady Gaga was victorious in a key court ruling Friday when a judge ruled that Mind Candy, the company responsible for the kids Internet sensation Moshi Monsters, can no longer use a Gaga-inspires song called "Peppy-Razzi."

Moshi Monsters is a social online game where kids between the ages of 7 and 12 adopt and care for infant likenesses of popular celebrities, including a character called Lady Goo Goo.  Friday's ruling prohibits Lady Goo Goo from singing the song, but does allow her to continue appearing in the game.

The ruling is part of an ongoing case that is considered a key in determining trademark implications of parody artists.  Mind Candy, through a new entity called Moshi Music, has planned to release the parody on iTunes as part of a campaign to market its game.

Gaga, of course, wants the character to be completely be eliminated,  but the court stopped short of granting her that.  The case is not Gaga's first attempt to protect her trademark, as she sued a London ice creamery earlier this year to stop them from selling ice cream made from human breast milk called Baby Gaga.
