CPCs are returned as null

Hi,

When using a query like below, the CPCs are being always returned as null.

https://webapi.patentsview.org/api/patents/query?q={%22patent_id%22:%226748283%22}&f=[%22app_date%22,%22assignee_first_name%22,%22assignee_id%22,%22assignee_last_name%22,%22assignee_organization%22,%22assignee_country%22,%22assignee_state%22,%22assignee_city%22,%22assignee_sequence%22,%22assignee_location_id%22,%22citedby_patent_date%22,%22citedby_patent_id%22,%22citedby_patent_title%22,%22cpc_sequence%22,%22cpc_group_id%22,%22cpc_group_title%22,%22inventor_first_name%22,%22inventor_id%22,%22inventor_last_name%22,%22inventor_country%22,%22inventor_state%22,%22inventor_city%22,%22inventor_sequence%22,%22inventor_location_id%22,%22nber_subcategory_id%22,%22nber_subcategory_title%22,%22patent_abstract%22,%22patent_average_processing_time%22,%22patent_date%22,%22patent_num_cited_by_us_patents%22,%22patent_number%22,%22patent_processing_time%22,%22patent_title%22,%22patent_type%22,%22uspc_mainclass_id%22,%22uspc_mainclass_title%22,%22uspc_sequence%22,%22govint_org_id%22,%22govint_org_name%22,%22govint_raw_statement%22]

Hello,  I can confirm this…

Hello, 

I can confirm this behaviour.  Earlier this week, this API call returned results - now null:

https://api.patentsview.org/cpc_subsections/query?q={"_begins":{"cpc_subgroup_id":["H04"]}}&f=["cpc_subgroup_id","cpc_subgroup_title"]&s=[{"cpc_subgroup_id":"asc"}]

FYI,

G.

Howdy, For some reason you…

Howdy,

For some reason you are no longer able to query by cpc_subgroup_id.  They discontinued a number of endpoint recently and I'm still looking for an explanation and a replacement.

https://patentsview.org/apis/purpose for the link to an excel document with all of the discontinued queries.

Hello, this issue with CPC…

Hello, this issue with CPC queries returning null results is now resolved.

We have not discontinued endpoints yet, but PatentsView is moving to a new design for our API which will involve adapting query calls to fit the new specifications. If you would like to begin using the new endpoints, here is some information to use to do so,

 

Best,
