PCT AG-IP 5.090 How must the international application be signed?

5.090.   How must the international application be signed?  The signature should be executed indelibly in a dark color, preferably in black ink, so that it will appear clearly in a photocopy.  The name of each person signing the international application should be indicated (preferably typewritten) next to the signature.  Where the person signs on behalf of a legal entity, the capacity in which that person signs should also be indicated.
