Tushbaby, a California company whose fanny pack-meets-baby carrier product drew viral attention, has filed a slate of lawsuits in Florida and New York to fend off imitation products being sold on Amazon and other online markets.

A complaint filed by Boies Schiller Flexner of Miami in June in the U.S. District Court for the Southern District of Florida named several defendants it said were individuals and businesses based in China that offered its products online to consumers in Florida and throughout the United States.
