I'm used to being able to look up referenced provisionals in the Public Pair database by clicking on the link over their application number under the "Continuity Data" tab.
However, I've come across one case in which the provisional that was referenced in a published non-provisional (already published for over one year) does not have a link associated with it. Also, searching for the referenced application number directly does not find anything.
Is it possible that the applicant referenced a provisional that does not actually exist, or that did not get filed properly? Another possibility would maybe be a typo in reproducing the number in the non-provisional application.
In any case, does that mean that the non-provisional will not have the benefit of said provisional?
