On 5/30, NIH issued a new notice (NOT-OD-17-066) on that updates and replaces the prior NIH policy on post-submission materials:
This Notice updates and replaces the NIH, AHRQ, and NIOSH policy for post-submission materials for applications submitted for due dates on or after September 25, 2017. It expands that policy to include citations to issued patents as allowable post-submission materials. Post-submission materials are those submitted after submission of the grant application but prior to initial peer review. They are not intended to correct oversights or errors discovered after submission of the application, but rather allow applicants the opportunity to respond to unforeseen events.
