When should property rights statements to DOE or NASA be filed?

According to MPEP 150, property rights statements to DOE or NASA can be filed at any time, but they should be kept up-to-date to reflect accurate property rights at the time of application allowance. The MPEP states:

Property rights statements to DOE or NASA may be filed at any time but should be updated if necessary to accurately reflect property rights at the time the application is allowed.

Additionally, the USPTO typically sends an informal request for a property rights statement shortly after filing to applicants whose nonprovisional applications are marked as being of interest to DOE or NASA. While there’s no formal time period set, a response within 45 days is recommended to expedite processing.
