Funding agencies may have a required question or field on their standard forms to capture whether proprietary information is included. An affirmative to the question indicates that patentable ideas, trade secrets, or privileged information is included. Consulting the agency specific grant application guidelines will advise on how to identify such information in the body of the application materials.
For example, the National Science Foundation (NSF) requires the “Proprietary or Privileged Information” box on the Cover Sheet to be marked, in addition to clearly marking the information in the proposal with an appropriate label or legend. [NSF Proposal and Award Policies and Procedures Guide (PAPPG) Chapter II.D.1]
Similarly, to identify proprietary information on a National Institutes of Health (NIH) grant proposal, check “Yes” to Question 3 on the “Other Project Information” page on the application forms pages, and clearly mark each line or paragraph containing the proprietary information.
[General Instructions for NIH and Other PHS Agencies (Section G. 220)]
Other federal agencies may have similar application requirements, please read your grant solicitation or guidelines carefully.
