To protect these secrets, there are several common ways that companies use to protect these secrets. These include the use of a patent, a non-compete agreement, a no-pocher agreement and a confidentiality agreement (NDA). It is important that, even if you have a secret designed, signed and agreed upon by all parties involved, you must take steps to limit the amount of information and the number of people who have access to the trade secret and all confidential information. The time limits should apply to ordinary confidential information, but not to trade secrets, and you must expressly state this in your NDA. If you only use the legal agreement for trade secrets, do not mention any time limit.
