Mariah Carey is trying to trademark "Queen of Christmas." Some artists say she doesn't hold that title – and they're trying to stop her.

Mariah Carey is trying to trademark the title "Queen of Christmas," believing she is synonymous with Christmas thanks to her enduring 1994 hit "All I Want for Christmas Is You." However, the singer's request has been met with opposition – and at least one artist is taking legal action to block it.

Carey's legal team filed a petition to trademark "Queen of Christmas" in March 2021, but it was made public in July, giving others the opportunity to oppose it.

Christmas songwriter Elizabeth Chan did just that. She is a full-time songwriter who has been dubbed "The Queen of Christmas" too, her lawyers at WilmerHale law firm say.
