TWIN I.V.I. Cookware Series

Original: Zwilling J.A. Henckels Kitchenware, China

Knockoff: Guangdong Xinkeda Industry, China

Two Chinese companies are battling over the design of this cookware set and could end up in court soon. Zwilling holds a registered patent on the product, but still has to go through the costly process of shutting down the rip-off operation. The original's price was $122; the fake, only $14.
