[Pct] BENEFIT CLAIM VS. PRIORITY CLAIM --> retroactive effect in USA of 'disclaiming priority' Withdraw of Priority Claim Under Rule 90bis.3

[William Ahmed]

 Thank you David.
Rule 90bis.3 [reproduced below] refers to a priority claim under Article 8(1) of the PCT treaty [also reproduced below]
It seems like "priority claim" is defined under Article 8(1) of the PCT treaty as a Paris convention claim.AND It seems like domestic benefit claims (i.e. as far as the PCT treaty is concerned) would be under Article 8(2) of the PCT treaty.
SEE APPENDIX BELOW -- emphasis added
Do you agree?
Thanks,Bill
APPENDIX 


90bis.3       Withdrawal of Priority Claims

(a)  The applicant may withdraw a priority claim, made in the international application under Article 8(1), at any time prior to the expiration of 30 months from the priority date.



Patent Cooperation Treaty (PCT)

Article 8
Claiming Priority


(1)  The international application may contain a declaration, as prescribed in the Regulations, claiming the priority of one or more earlier applications filed in or for any country party to the Paris Convention for the Protection of Industrial Property.

(2)(a)  Subject to the provisions of subparagraph (b), the conditions for, and the effect of, any priority claim declared under paragraph (1) shall be as provided in Article 4 of the Stockholm Act of the Paris Convention for the Protection of Industrial Property

(b)  The international application for which the priority of one or more earlier applications filed in or for a Contracting State is claimed may contain the designation of that State. Where, in the international application, the priority of one or more national applications filed in or for a designated State is claimed, or where the priority of an international application having designated only one State is claimed, the conditions for, and the effect of, the priority claim in that State shall be governed by the national law of that State.

 OK, I see. The dates you're asking about are governed by national law in each daughter jurisdiction.  So it could well be that country x allows you to disclaim the provisional in the way you contemplate (and thus when you file national stage at 42 months in x, you are welcomed with open arms), and country y doesn't (and says, when you file at 42 months, "too bad so sad.  You can't move the filing deadlines in our country via that move.")  I have no knowledge of any of that. 

The U.S. application--and its entire parentage--is governed by U.S. statutory law, sections 119(e), 120, 361, 365 (from memory).  Paris Art 4(A)(1) expressly excludes the rest of Art 4 from same-country-to-same-country priority chains ("in the other countries").  The word "benefit" vs "priority" is a helpful mnemonic to help you keep two things straight, but the real substantive difference is the word "other" in Art 4(A)(1.

 HI David,For purposes of Europe and Japan, the Applicant would lose the priority date, and the earliest date would be the date the PCT was filed (i.e. the PCT filing-date)The invention was never disclosed during the priority year. 18 month publication was 6 months after the PCT filing-date.
So the WIPO publication would not hurt the application.
There is a small risk that someone else filed (or published) during the priority year, but the Applicant has no money for non-US filings, so this is better than nothing.
BOTTOM LINE --> I am confident for non-USA jurisdictions -- it is QUITE possible to prosecute an EPO patent with no priority claim. That is what would happen here - the Paris convention claim would just die.
But I AM concerned about 'collateral damage' of PCT 90.bis.3 to the US designation (in my case, the CON).

The text of PCT Rule 90.bis.3 is -->

90bis.3       Withdrawal of Priority Claims

(a)  The applicant may withdraw a priority claim, made in the international application under Article 8(1), at any time prior to the expiration of 30 months from the priority date.
Could we argue that the term priority claim is very specific, and only applies to the 'foreign priority' for the purposes of the US designation of the PCT?  
If yes, is this a 'bullet-proof argument'?
Thanks,Bill

 "wants the extra year for non-US national-phase entries"
I don't see how this is remotely feasible after the application publishes, and after the provisional has been priority-claimed by a PCT.  Look at the wording on the face of Paris Convention Article 4 https://www.wipo.int/wipolex/en/text/288514  Withdrawal of an earlier application is impossible after the earlier application is "laid open to public inspection," "leaves any rights outstanding" (including U.S. rights), or "served as a basis for claiming a right of priority."  You don't need to see case law (and this is all domestic law anyway -- U.S. case law is irrelevant).  Look at the words on their face.

Second, alternatively, if they want to assert that the withdrawal counts in the USA, I'd say that 90bis.6 refers to a priority claim under Paris Article 4, and the benefit claim in the USA was not made under the Paris convention but rather under domestic US legislation, so the withdrawal of the priority claim per 90bis.6 is irrelevant in the USA, since the US benefit claim was never withdrawn.


This sounds good to me based on logic, but I am not as well versed in the case law as many on this list.
Would this argument of 'benefit vs. priority' be strong enough to rely on?From a business point of view, my client would NOT risk the US date, but she definitely wants the extra year for non-US national-phase entries if it can be done without risking the US date.
What do people think?
Thanks!Bill

 I have a situation similar to Bill's, but which differs in two important ways: the US application is not a bypass but a straight 371; and the US patent has already been issued. More specifically:
Applicant has a PCT application that claims the benefit/priority of a US provisional.  The 30 month deadline is approaching.  Applicant entered us national stage (371 application) early and already has an issued us patent.  Applicant now wants to withdraw the priority claim in the PCT in order to delay the 30-month deadline for national phase applications.  As Bill noted, pct rule 90bis.6 (a) says 
"(a)  Withdrawal under Rule 90bis of the international application, any designation, any priority claim, the demand or any election shall have no effect in any designated or elected Office where the processing or examination of the international application has already started under Article 23(2) or Article 40(2)."  
So it seems that per rule 90bis.6, withdrawal of the priority claim in the still-pending PCT application will not affect the benefit claim in the USA, since that benefit claim was made before withdrawal of the priority claim in the PCT application. That's good, b/c the applicant doesn't want to forego its benefit/priority claim in the USA.  However, I don't find PCT rule 90bis.6 written into the statute in the USA.  So in principle, an adverse party may later assert that the carve-out in PCT rule 90bis.6 doesn't apply in the USA, since the USA never enacted Rule90bis.6, and therefore the withdrawal of the priority claim in the still-pending PCT means that the issued US patent (a 371 of the PCT) is not entitled to the claimed benefit date.My response would be two-fold. First, rule 90bis.6 does apply, even in the absence of explicit US domestic legislation saying so, and so the withdrawn priority claim has no effect in the USA since national phase was already effected before the withdrawal. Second, alternatively, if they want to assert that the withdrawal counts in the USA, I'd say that 90bis.6 refers to a priority claim under Paris Article 4, and the benefit claim in the USA was not made under the Paris convention but rather under domestic US legislation, so the withdrawal of the priority claim per 90bis.6 is irrelevant in the USA, since the US benefit claim was never withdrawn.

Anyone see holes in this?

 Dear List,My question is below under "MY QUESTION TO THE LIST."
BACKGROUND
(A) On Jan 15, 2023, we filed a US provisional  -- serial number 63/XXX,XXX(B) On Jan 15 2024, we refiled the US provisional as a PCT (serial number PCT/IB2024/ABCDEF), claiming Paris convention priority to the US provisional 63/XXX,XXX(C)  In Feb 2024 the PCT entered the USA as a 111 bypass as US non-provisional 18/ZZZ,ZZZwith the following two two domestic benefit claims 
(1) 18/ZZZ,ZZZ is a CON of PCT/IB2024/ABCDEF filed on Jan 15, 2024(2) PCT/IB2024/ABCDEF claims priority to US provisional 63/XXX,XXX filed on Jan 15, 2023

NOTE - the invention was NOT disclosed by the client before July 2024 when WIPO published PCT/IB2024/ABCDEF

SITUATION NOW 
(i) US non-provisional 18/ZZZ,ZZZ is pending and has not received an office action.  A filing receipt with the both domestic claims mailed in March 2024(ii) the 30 month deadline of PCT/IB2024/ABCDEF is on July 15, 2025.(iii) the client has absolutely NO money for non-USA national-stage entries. They used to have money - now it's gone(iv) the client is optimistic that they will get money in late 2025 or early 2026(v) the client wants to Withdraw the Priority Claim [Under Rule 90bis.3] to US provisional 63/XXX,XXX [filed Jan 15, 2023] - this would reset the PCT's clock,and the national-phase entry deadline of PCT/IB2024/ABCDEF would move from July 2025 to July 2026

MY CONCERN
If we withdraw priority in WIPO/PCT, I am concerned about 111 bypass filed in Feb 2024There is no direct domestic benefit claim from the 111 bypass to the US provisional - the domestic benefit claim of the 111 bypass to the US provisional is "via the PCT"
MY QUESTION TO THE LIST --> 
If I now withdraw the priority claim from the PCT to the US provisional, would that void the domestic benefit claim from the PCT to the US provisional which was recognized by the USPTO in the March 2024 filing receipt for the 111 bypass ?
I *think* that we are OK under "90bis.6 Effect of Withdrawal"   
   - (a) Withdrawal under Rule 90bis of the international application, any designation, any priority claim, the demand or any election shall have no effect in any designated or elected Office where the processing or examination of the international application has already started under Article 23(2) or Article 40(2).
but I know that in this business, there are traps, especially with these kinds of procedures.
THOUGHTS ??
IF you read this far, a WARM thank you.
What do you think?
Thanks,Bill --
