How are they prepared? My guess is that they are soaked in something to soften them to save the heating cost of cooking beans for hours. (Many information sites give a rote answer that “prepared beans” means that the beans are boiled, but that is false because organic beans do not say “prepared”.) All regular beans say “prepared beans”. All organic beans say “beans”.
The internet answers are mostly just “deduced” instead of researched. In other words, somebody asks a question and the other person thinks about it and gives the obvious answer that pops in his head, which is no answer at all. No research exists online, and I even sent a letter to a company and got no reply.
