Is there any way to retrieve results for both A1 and B1?

Post by URTour » Wed Mar 07, 2018 1:03 pm

Hello

I have run into a slight problem with EPO. Sometimes, when I search for a specific, name or organisation, I’m only able to retrieve either the A1 or B1 entry. For instance when the person or institute that I search for is only mentioned in the A1 entry, then I obviously do not get the B1 entry for the same EP publication number if that same person/organisation is not mentioned there as well.

Is here any way around this? Basically, I want EPO to retrieve both the A1 and B1 entry for the same publication as long as one of them satisfy my search criteria.

Dear URTour,

Could you please indicate which EPO product you use? Is it "EP full-text search", "EP Bulletin search", Espacenet, ...?

Thanks in advance for your answer,

Best regards,

EPAL team

Simply use the "published-data" GET request and you'll get all publications in the response.

Publications are stored in the "exchange-document" property.

If only one publication is available, it is declared as an object "{ }" and the "@kind" key usually has the value "A1" (first publication with search report) or "A2" (first publication without search report). If "exchange-document" is declared as an array, multiple publications such as "A1" and "B1" are included.

So if you parse your JSON/or XML etc for all configurations and array items of "exchange-document", you should be all set.

Example:

Code: Select all

{
    "ops:world-patent-data": {
        "@xmlns": {
            "ops": "http://ops.epo.org",
            "$": "http://www.epo.org/exchange",
            "xlink": "http://www.w3.org/1999/xlink"
        },
        "exchange-documents": {
            "exchange-document": [            <--- contains several published documents
                {
                    "@system": "ops.epo.org",
                    "@family-id": "50114546",
                    "@country": "EP",
                    "@doc-number": "2954739",
                    "@kind": "A2",                    <--- first published document
                    "bibliographic-data": {



                           (...)
                           (...)
                           (...)
                           (...)
                           
                           
},                                                         
{
                   "@system": "ops.epo.org",
                    "@family-id": "50114546",
                    "@country": "EP",
                    "@doc-number": "2954739",
                    "@kind": "B1",                   <--- second published document
                    "bibliographic-data": {

                           (...)
}]
