The Hershey Insider reports

that The Hershey Co. is taking legal action against Williams-Sonoma because the kitchenware company's

Chocolate Bar Brownie Pan

looks a lot like a Hershey bar. The pan "creates one large brownie or cake, scored into 12 embossed chocolate-bar shapes," according to Williams-Sonoma's description. A

Hershey bar

is divided into 12 embossed little bars as well.

A Law.com story on the matter

says Hershey claims the pan "unlawfully trades on the goodwill and reputation Hershey has established through its use and promotion of that product configuration trademark."
