Proprietary Information is non-public technical, scientific, business, or commercial information shared by one party with the expectation that it will be protected and used only for an agreed purpose, such as evaluating or performing a sponsored project. It can include data, prototypes, methods, software, pricing, product plans, or unpublished results, shared in writing, digitally, or verbally. The agreement specifies how it must be identified, stored, limited to authorized personnel, and how long protection lasts, with standard exclusions for public or independently developed information.
