Change to signature requirements for PCT declaration of inventorship
New inventors' signature requirements for PCT applications.
From 1 October 2005, the inventor(s)’ signature(s) must appear on the declaration of inventorship under PCT Rule 4.17(iv) (which may be filed during the international phase for the purposes of the designation of the USA).
Previously, if the inventor had signed the PCT Request Form (PCT/RO/101), and the declaration of inventorship was filed with the international application, it was not necessary to have the inventor sign the declaration itself (see Section 214(a) of the Administrative Instructions under the PCT).
