When shooing Buffalo, New York-based Kaitlyn Pan Group LLC off the Amazon selling platform over the discount company’s imitations of luxury shoes by Italian brand Valentino didn’t work to curb the sale of knockoffs, the online retailer and the Italian fashion company paired up and decided to sue.

The companies filed their joint lawsuit this week claiming Kaitlyn Pan’s strikingly similar shoes are counterfeits of Valentino’s iconic “Garavani Rockstud” metal-embellished stilettos and violate the company’s intellectual property rights, according to Reuters.

Amazon told reporters that it gave Kaitlyn Pan’s seller account the boot in late 2019 and “despite multiple notices of infringement and a cease and desist order, Kaitlyn Pan continues to import, distribute, sell, and offer infringing products on kaitlynpanshoes.com.”

This is Amazon’s first joint litigation with a luxury fashion brand and it is Valentino’s first joint litigation with an online retailer, according to fashion news site Women’s Wear Daily, which has been covering the ongoing problem with online retail and counterfeit fashion.
