Radar has detected a surge in trademark suits around the country, headlined by Mattel’s attempt to block a “Barbie-Que” brand of potato chips featuring rapper Nicki Minaj, and by Deckers’ suit against three makers of strapped, fuzzy slippers and sandals.

Mattel and Minaj teamed up 10 years ago on a one-of-a-kind Nicki Minaj Barbie Doll that was donated to charity. Minaj also sang “Barbie Dreams” on her 2018 album “Queen.”
