NDA types
1) One-way (unilateral)—typical when an IP owner discloses to a contractor. 2) Mutual—both sides disclose, e.g. M&A due diligence. 3) Multi-party—three or more parties, e.g. consortium bidding. 4) Employee NDA plus non-compete and non-solicit (non-compete needs consideration or it is void under CCC 150).
