Crocs sues Five Below for alleged patent, trademark infringement

Crocs accused Five Below of attempts "to create and sell knockoff versions" to try and "trade on the immense popularity" of its brand, citing the retail chain's "Juniors Charm Clog." It's almost a story of resilience — how Crocs went from just about dead to back in high demand; however, the rise of knockoffs has led the company to file suit over trademark and patent infringement.
