*/CONFIDENTIAL. PRIVILEGED./*

On a lark, I put Katherine's question, and then a follow-up question 
into IronCrow's LLM and selected the special Interrogate option that is 
pre-trained on "PCT Treaty, Regulations and Administrative 
Instructions". I'm putting the actual answer here because I thought the 
rest of the listserv might be interested in the state of patent practice 
specific research tools. What I did not include is the verbatim cited 
sources that are attached to the end of each answer automatically so 
that you can verify the LLM's 'reasoning'. BTW -- I am not related to 
IronCrow except as a user and a periodic offerer of rambling thoughts, 
grumblings, and feature requests that Will is gracious enough to 
consider helpful feedback.

I felt like Response 1 was maybe technically accurate but not as 'to the 
point'. My follow-up request I felt like provided some nice citations 
that I might find helpful to copy and paste into a response, for example 
(after validating the citation!).

QUESTION 1 (slightly edited): I filed an application in which the 
figures were mistakenly misnumbered and now I’ve received RO/106 and 
RO/107 notices stating that my filing date will be corrected to the date 
on which I file the corrected drawings.  This is such a minor thing, I’m 
hoping there’s a way to keep the priority date (the 1-year deadline has 
passed) and, hopefully, the filing date. How should I respond and argue 
that I have the right to keep my filing date since all the subject 
matter was present, there was just some numbering issues.

RESPONSE 1:


    Understanding the Issue

You've received RO/106 and RO/107 notices indicating that your 
international filing date will be corrected to the date when you submit 
corrected drawings due to misnumbered figures. This is concerning since 
your priority period (1-year deadline) has already passed.


    Legal Framework

The key provision that applies to your situation is *Article 14(2)* of 
the PCT, which states:

    "If the international application refers to drawings which, in fact,
    are not included in that application, the receiving Office shall
    notify the applicant accordingly and he may furnish them within the
    prescribed time limit and, if he does, the international filing date
    shall be the date on which the drawings are received by the
    receiving Office. Otherwise, any reference to the said drawings
    shall be considered non-existent."


    Important Distinction to Make

The critical point to argue is that your situation does not involve 
*missing drawings* but rather *misnumbered drawings* that were actually 
present in the application. This is a significant distinction.


    Recommended Response Strategy

 1.

    *Clarify that the drawings were present*: Emphasize that all
    drawings were physically included in the application at filing -
    they were merely misnumbered. This is not a case where drawings were
    referenced but not included.

 2.

    *Argue for rectification of obvious mistake*: Request rectification
    under *Rule 91* of the PCT, which allows for correction of obvious
    mistakes. According to Rule 91.1(c):

    "The competent authority shall authorize the rectification under
    this Rule of a mistake if, and only if, it is obvious to the
    competent authority that, as at the applicable date under paragraph
    (f), something else was intended than what appears in the document
    concerned and that nothing else could have been intended than the
    proposed rectification."

 1.

    *Emphasize that this is a minor defect*: The misnumbering of figures
    that were actually present should be treated as a correctable defect
    under Article 14(1)(a)(v) and Rule 26.3, which deals with physical
    requirements, rather than a case of missing drawings under Article
    14(2).

 2.

    *Request maintenance of the original filing date*: Since the
    drawings were physically present at filing (just misnumbered), argue
    that the requirements of Article 11(1) were met at the time of
    filing, particularly Article 11(1)(iii)(d) which requires "a part
    which on the face of it appears to be a description."


    Procedural Steps

 1.

    Submit your response within the time limit specified in the notices.

 2.

    Include a clear explanation that distinguishes between misnumbered
    drawings (your case) and missing drawings (Article 14(2) case).

 3.

    Submit the corrected drawings with proper numbering.

 4.

    Request that the correction be treated as a rectification of an
    obvious mistake under Rule 91 or as a correction of a physical
    requirement defect under Rule 26.3.

 5.

    Cite Section 325 of the Administrative Instructions, which outlines
    the procedure for corrections of defects under Rule 26.4 and
    rectifications of obvious mistakes under Rule 91.


    Conclusion

The key to your argument is establishing that this is not a case of 
missing drawings (which would justify a change in filing date under 
Article 14(2)) but rather a case of misnumbered drawings that were 
physically present at filing (which should be correctable without 
affecting the filing date).

If the receiving Office maintains its position, you may need to consider 
further procedural options, but this initial response should present a 
strong case for maintaining your original filing date.


QUESTION 2: What are the key limitations on the office's authority to 
change the filing date? Please use quotes from the appropriate statutes, 
rules, or guidelines. Would pointing to a provisional that referred to 
the subject matter of the figures in the proper order help?

RESPONSE 2:


    1. Requirements for Establishing Filing Date

Article 11(1) establishes the basic requirements for according an 
international filing date:

    "The receiving Office shall accord as the international filing date
    the date of receipt of the international application, provided that
    that Office has found that, at the time of receipt:
    (i) the applicant does not obviously lack, for reasons of residence
    or nationality, the right to file an international application with
    the receiving Office,
    (ii) the international application is in the prescribed language,
    (iii) the international application contains at least the following
    elements:
    (a) an indication that it is intended as an international application,
    (b) the designation of at least one Contracting State,
    (c) the name of the applicant, as prescribed,
    (d) a part which on the face of it appears to be a description,
    (e) a part which on the face of it appears to be a claim or claims."


    2. Missing Drawings vs. Defects in Drawings

Article 14(2) specifically addresses missing drawings:

    "If the international application refers to drawings which, in fact,
    are not included in that application, the receiving Office shall
    notify the applicant accordingly and he may furnish them within the
    prescribed time limit and, if he does, the international filing date
    shall be the date on which the drawings are received by the
    receiving Office. Otherwise, any reference to the said drawings
    shall be considered non-existent."

This provision applies only when drawings are completely missing, not 
when they are present but contain defects such as misnumbering.


    3. Physical Requirements and Correctable Defects

Rule 26.3 limits the authority to reject applications for physical defects:

    "The receiving Office shall check:
    (i) the international application for compliance with the physical
    requirements referred to in Rule 11 only to the extent that
    compliance therewith is necessary for the purpose of reasonably
    uniform international publication;"

Rule 26.5 further limits the consequences of physical defects:

    "The receiving Office shall decide whether the applicant has
    submitted the correction within the applicable time limit under Rule
    26.2, and, if the correction has been submitted within that time
    limit, whether the international application so corrected is or is
    not to be considered withdrawn, provided that no international
    application shall be considered withdrawn for lack of compliance
    with the physical requirements referred to in Rule 11 if it complies
    with those requirements to the extent necessary for the purpose of
    reasonably uniform international publication."


    4. Rectification of Obvious Mistakes

Rule 91.1(c) provides for rectification of obvious mistakes:

    "The competent authority shall authorize the rectification under
    this Rule of a mistake if, and only if, it is obvious to the
    competent authority that, as at the applicable date under paragraph
    (f), something else was intended than what appears in the document
    concerned and that nothing else could have been intended than the
    proposed rectification."

Rule 91.3(c)(i) states that when rectification is authorized:

    "Where the rectification of an obvious mistake has been authorized
    under Rule 91.1, it shall be effective:
    (i) in the case of a mistake in the international application as
    filed, from the international filing date;"


    Would Pointing to a Provisional Help?

Pointing to a provisional application that referred to the subject 
matter of the figures in the proper order could potentially help, but 
not directly under the PCT framework. The key arguments should focus on:

 1.

    The misnumbered figures represent an "obvious mistake" under Rule
    91.1 that should be rectifiable without changing the filing date.

 2.

    The drawings were actually present in the application (just
    misnumbered), so Article 14(2) regarding missing drawings should not
    apply.

 3.

    Misnumbering of figures is at most a physical defect under Rule
    26.3, which should not result in the application being considered
    withdrawn if it meets the minimum requirements for reasonably
    uniform international publication.

While the provisional application might demonstrate the applicant's 
intent regarding the correct numbering, the stronger argument is that 
the misnumbering is an obvious mistake that should be rectifiable 
without affecting the filing date, since all the drawings were 
physically present at filing.
