Mattel is known for its strong protection of the Barbie brand and has been involved in several notable lawsuits to defend its intellectual property. One such lawsuit was against Aqua over their hit song "Barbie Girl." The case ultimately ruled in Aqua's favor, stating that the song was a parody and protected under fair use. Mattel continues to enforce its brand through collaborations and licensing deals, with over 100 Barbie-themed collaborations currently in progress.
