Filing a patent with national security implications? Check your filing receipt for a foreign filing authorization before filing outside the US.
After you file a US patent application, the USPTO will send you a filing receipt. On page two of this receipt, you will usually find the words: “If Required, Foreign Filing License Granted: [date]”.
What does this mean? Welcome to the interesting rules involving patents and national security.
Under the Invention Secrecy Act of 1951, the US government has the right to classify patent applications that, in the opinion of the USPTO, may pose a threat to the security of the US. In effect, the USPTO subjects every new patent application to at least a cursory security review. Think of it as a patent application TSA (airport style) inspection.
The vast majority of all applications will pass through the security review quickly, and those that pass will get the “Foreign Filing License Granted” clearance. But occasionally, something catches the interest of the national security review staff. For example, I can pretty much guarantee that a patent application for “Improved methods for detecting stealth aircraft” will get a very careful national security review!
What if you are planning to also file your invention outside the US? Doing a foreign patent filing (even for a design patent) without proper advance approval is much like trying to jump a TSA line. Folks get excited, and unfortunate things may happen. At a minimum, you could easily lose the US patent rights on your invention.
The amount of security review can vary depending upon world events. For example, after 9/11, it appears as if an unusually large amount of scrutiny took place. Scrutiny may also vary according to what areas of technology are considered sensitive at any given time.
So the take-home lesson, which is particularly relevant for US inventors of patent applications with potential dual-purpose civilian/military uses, is to look for that “Foreign Filing License Granted” small print before filing outside the US. Alternatively, if there has been a delay, file a PCT application through the USPTO, rather than filing directly outside the US.
