Hope you'll be able to help me out here - I really can't figure out what I am doing wrong.
I am trying to access information on all patents within a certain cpc-code. Doing that I am iterating over the range-parameter with steps of 100 from one to 12241. It works fine until I reach 2001-2100, why is that?
The scenario is reproducible in the developers console as specified here:
works fine:
http[colon][slash][slash]ops.epo[dot]org[slash]3[dot]1[slash]rest-services[slash]published-data[slash]search[slash]biblio?q=cpc%3DY02E10%2F72&Range=1001-1100
yields 400-error "Invalid query":
http[colon][slash][slash]ops[dot]epo[dot]org[slash]3[dot]1[slash]rest-services[slash]published-data[slash]search[slash]biblio?q=cpc%3DY02E10%2F72&Range=2001-2100
I have tried both GET and POST requests but none seem to work. Obviously I would prefer a POST-solution because the team asks that bulk data retrievals is to be done so.
Is there some kind of restriction I have missed? The preceding authentification works fine for me. I would not suspect that my quota is exhausted. Full content of the reply below:
