I was reading the confidentiality article on this site and I have a question. If you have a competitor trying to buy your business, and, even under a confidentiality agreement you disclose your trade secrets to the competitor, what stops him from using those secrets against you? I understand that in a world that is perfect, they should not do this, but how likely is that? This is assuming the sale did not go through of course. Any tips on how to mimize the damage or get additional protection?
