... Bottom line;
Trade secrets are protected information. ...
What I have quoted above of your post, justalayman, is the key to any defense JasonKal
might have if he were to disclose the secret recipe to others outside the company or companies involved.
A company that has not taken appropriate measures to keep a secret confidential may no longer have this secret protected by law as a trade secret. The secret, essentially, falls into the public domain.
I have some question as to how the secret recipe was protected if all of the employees of the company knew the secret. Without specific confidentiality/non-disclosure agreements written and signed by the employees who were given access to the recipe, a company would need to have taken other steps to ensure the recipe remained confidential. This could be possible if a company is a small, family-owned business with few employees. It could be accomplished through posted warnings throughout the company buildings, and it could be accomplished through notifying all employees personally that the information they were handling was to remain confidential. You have a duty of trust.
But ensuring confidentiality becomes more difficult the larger the company is (which is why large companies require signed confidentiality/non-disclosure agreements and limit exposure to the secret to those who need to know).
I am not saying, by the way, that JasonKal should want to be a person who attempts to show a court that the trade secret is not really a trade secret and the company failed to protect it properly. The penalties for losing a trade secret action are too severe and he is likely to lose.
At any rate, I think JasonKal has already indicated that, although he mulled over what would happen if he were to sell the recipe online, he has no real intention of testing the law by doing so.
