Brief Summary

This chapter covers the confidentiality of patent applications and patent related documents. The focus is on who may or may not access particular application types.

Any patent application that contains a sensitive issue will be placed under a secrecy order by the PTO. Absolutely no member of the public may view these patents even after they have issued.

Foreign filing licenses must be issued if an applicant wants to apply for a patent on the same subject matter in a foreign country immediately after filing for a U.S. patent.
