A listserv member asks to post anonymously:

    A PCT filed 2/1/24 was based on a provisional filed 2/1/23. The spec
    had the correct priority claim but the PCT Request form did not
    include the priority claim at all.

    I interpret Rule 26bis as being very clear that you have 16 months
    from the priority date to correct a priority claim. I believe that
    priority cannot be fixed for the PCT.

    Correct or incorrect?
