Patent infringement filed against Ufood- http://news.priorsmart.com/dietgoal-innovations-v-ufood-restaurant-group-l7fe/ . Can anybody explain why there are dozens of other restaurants using their product- in fact Ufood is listed on the nutrionix website as a client. http://demo.nutritionix.com/clients/. On the surface it looks like they are all doing the same thing.
