In many cases, the use of an NDA is essential, for example. B to retain employees who develop patentable technologies when the employer intends to file a patent. Confidentiality agreements have become very important given the nascent outsourcing industry in India. In India, an NDA must be stamped to be a valid enforceable document. The explicit “purpose” of the NDA ends when the parties enter into a comprehensive agreement. The comprehensive agreement usually contains a standard “miscellaneous” provision which states that it constitutes a complete understanding of the parties and that no other oral or oral agreement is valid on the matters dealt with in the agreement. Such a provision denies the validity of the NDA after the signing of the global agreement. Nevertheless, the NDA should be expressly denounced, but confidential information disclosed under the NDA and prior to the signing of the trade agreement by the parties should be included in this agreement. In California (and other U.S. states), there are special circumstances regarding confidentiality agreements and non-compete rules.
California courts and legislators have signaled that they value an employee`s mobility and entrepreneurship in general more than protectionist doctrine.   However, once the parties have reached a comprehensive agreement, both parties should ideally be able to discover the existence of the contract.
