No results found due to inconsistent publication IDs?
Posted: Tue Oct 27, 2020 11:05 am
Hello,
I've been using the EPO OPS to search for records on a number of patent publications.
I'm having trouble retrieving records for a few of the IDs and it seems to be due to inconsistencies in the IDs themselves.
For example, US20150240233. If I run the following query through the EPO OPS I get the result "no results found": "http://ops.epo.org/3.2/rest-services/fa ... 233/biblio"
However if I search for the patent using the Espacenet patent search tool I get a match with the publication ID US2015240233, which differs by a single digit from my original query ID. If I search the google patents database, both US20150240233 and US2015240233 return the same results - it seems they both refer to the same patent publication. If I query the OPS API using the following URL, I do get the expected results: "http://ops.epo.org/3.2/rest-services/fa ... 233/biblio"
I have a number of records like this - for all of them a search for my original ID on espacenet returns results for a very similar ID (missing one or more digits).
Do you know why a search of the espacenet database returns results for these IDs yet a query using the OPS API is not successful? Is there anything I can do besides manually searching for all affected IDs using the Espacenet patent search tool and adjusting my original query IDs?
