[Pct] Check 371 continuity dates in Patent Center

[Suzannah K. Sundby]

I vaguely recall having a case about a year or two ago where I filled out everything correctly on the ADS (which was an uploaded, not a web-based one)... and the Filing Receipt indicated the PCT filing date a year after the real date... or maybe it was the foreign priority a year after the PCT date.

Either way, the dates were correct in my ADS... and somehow the USPTO screwed it up and I had to take the time to correct it...

Subject: [Pct] Check 371 continuity dates in Patent Center

We filed a 371 (U.S. national stage) application in early April.  The international filing date was, let's say, 09/01/23.  The international application # and filing date were correctly entered in Patent Center to initiate the filing.  The correct information was also entered in the ADS.

However, both the  Electronic Acknowledgement Receipt and the Electronic Payment Receipt listed the International Filing Date as 09/01/24.  We checked the continuity tab in Patent Center after noticing the error in the receipts, and it also lists 09/01/24.  (Clicking through the PCT link takes you to WIPO, where the International Publication naturally indicates the correct filing date of 09/01/23.)

Of course, we always carefully proofread the eventual Filing Receipt (which we don't expect to receive any time soon) for errors, but 371 filings shouldn't be able to have this type of error. This is an annoying waste of our time.

We contacted the consistently competent PCT Helpdesk. The representative had not seen this particular error, but he agreed that it would likely carry through to the eventual Filing Receipt if not corrected, which he is endeavoring to do. (Then we won't have to deal with a defective Filing Receipt as well as a corrected one, which means less paperwork down the line.)

Has anyone else experienced this?  I suggest proofreading 371 filing receipts very carefully, and if you are awaiting some, I also suggest checking the corresponding continuity dates in Patent Center.
