RC2 Sues Munchkin, Inc For "Sippy Cup" Patent Infringement

RC2, whom you probably know as the company that makes the lead-tainted Thomas & Friends toys, has filed a lawsuit against rival Munchkin, INC for allegedly infringing on a spill-proof sippy cup patent.

Munchkin, INC, which had no comment for the Chicago Sun-Times about the matter, does display a note on their spill-proof sippy cup product page proclaiming: Patents pending.

Quick, Munchkin, INC! Hire Verizon’s magical flying lawyers before RC2 gets them first.
