Mariah Carey won't be getting everything she wants for Christmas this year ... her attempt to trademark the phrase "Queen of Christmas" was just rejected, TMZ has learned.
The U.S. Trademark Trial and Appeal Board denied MC's attempt to trademark "Queen of Christmas" on Tuesday ... along with her attempts to lock down the rights to "Princess Christmas" and "Christmas Princess," according to a release given to TMZ.
Despite having some support ... legends like Darlene Love and singer Elizabeth Chan pushed back on MC -- Elizabeth filed an opposition, arguing no one should "monopolize" the word "Christmas."
As for what Mariah wanted to TM for, in her filing she said she planned to use the title for fragrances, lotions, nail polish, jewelry, cups, mugs, chocolate milk, coconut water ... as well as ornaments, toys, dog clothing, masks, lingerie and sweatshirts.
Elizabeth tells us, "Christmas is a season of giving, not the season of taking, and it is wrong for an individual to attempt to own and monopolize a nickname like Queen of Christmas for the purposes of abject materialism."
