"Certificate of Correction" of US patents not FullDocuments
Posted: Thu Apr 16, 2020 8:58 pm
Hello
I tried to get the full PDF publication from US5052622A.
Following the OPS manual I firstly obtain the correct link to this PDF document using the query
https://ops.epo.org/3.2/rest-services/p ... 2.A/images
This query retrieves one inquiryresult containing four documentinstances as follows:
[0] desc: FullDocument link: published-data/images/US/5052622/A/fullimage numberofpages:11
[1] desc: Drawing link: published-data/images/US/5052622/A/thumbnail numberofpages:4
[2] desc: FirstPageClipping link: published-data/images/US/5052622/PA/firstpage numberofpages:1
[3] desc: FullDocument link: published-data/images/US/5052622/X6/fullimage numberofpages:1
The documentinstance[3] is wrong. The link contains document kind X6 which is a "Certificate of Correction" of a granted patent. This Certificate of Correction is not a "FullDocument". It contains only one page, as is shown in the numberofpages field of documentinstance[3] and as can be seen in original on the USPTO's PAIR website. Incidentally Espacenet shows a link to the X6 document but the link is not working.
I have observed this error in OPS with other US patents having a Certificate of Correction. This error should be fixed because according to the OPS manual you must check for the documentinstance having desc=Fulldocument in order to obtain the correct link to the full PDF publication. If there are two documentinstances with desc=FullDocument there is ambiguity and it will not be possible to find out the correct link.
