How long can a secrecy order remain in effect for a patent application?

A secrecy order can remain in effect for a significant period. As stated in MPEP 120, “The secrecy order may remain in effect for the duration of the national emergency and six months thereafter and automatically expires at the end of that period.” However, it’s important to note that:

• The order can be renewed if necessary
• It can be terminated earlier if the reasons for its issuance no longer exist
• The total duration is subject to the provisions of 35 U.S.C. 181
