What languages does the U.S. Receiving Office accept for PCT applications?

The U.S. Receiving Office only accepts PCT applications in English. This is based on 35 U.S.C. 361(c), which states: “The U.S. Receiving Office continues to accept applications only in English.”

It’s important to note that this restriction applies specifically to the U.S. Receiving Office, and other countries may have different language requirements for PCT applications.
