On December 10, 2019 I provided training material to the USPTO (blog article, training material) about PCT Declaration Number 4. The idea is that a patent firm located outside the US might be trendy, modern, and up-to-date and might provide a signed inventor declaration (for later US purposes) at the time of filing a PCT application. The idea is that perhaps 1½ or 2½ years later, when the US national phase is entered, the signed declaration of inventorship for US purposes would already be in the file! The idea is that the formalities examiner in the DO/EO/US would take a look in the file and would pay attention to the presence of the signed PCT Declaration Number 4.
Unfortunately, all too often in recent months, we have had cases at the DO/EO/US where the formalities examiner at the USPTO fails to pay attention to the presence of the signed PCT Declaration Number 4 in our national-phase entry application file. Just today, for example, in one of our national-phase entry applications, the formalities examiner at the USPTO mailed out an official Filing Receipt along with Form PCT/DO/EO/903 (371 Acceptance Notice) dated July 17, 2023 falsely stating that we had failed to provide a “properly executed inventor’s oath or declaration” for our inventor.
It is hoped that the USPTO will once again in 2023 provide the training materials to its DO/EO/US formalities examiners, so that they can avoid making this mistake in the future for other US national-phase applicants.
