Several investors, organized through corporations, owned several Burger King restaurants in Wisconsin. The franchise agreement stated that franchise owners could not own competitor franchises. The investors formed other corporations and then obtained Hardee's franchises. Burger King terminated its franchise agreements with the owners for violating the franchise agreements. The owners argued that since the Burger King and Hardee's franchises were owned by different corporations the agreement had not been breached. Is that correct? [Deutchland Enterprises v. Burger King, 957 F.2d 449, 7th Cir. (1992)]
