Data Update: 11/6/2024​

The PatentSearch API is updated to contain data through 09/30/2024.

Updated Text Endponts​

For clarity and efficiency, granted and pre-grant text endpoints have been separated.
Granted text data can be retrieved at /api/v1/g_brf_sum_text/, etc.
Pre-grant text data can be retrieved at /api/v1/pg_brf_sum_text/, etc.
The json keys for these endpoints' responses have been updated correspondingly to g_brf_sum_texts, etc.

For consistentcy with other endpoints, responses from the /api/v1/publication/rel_app_text endpoint will now be delivered under the json key "rel_app_texts" instead of "rel_app_text_publications".

Bug Fixes​

  • An internal sorting field "patent_id_zero_prefix" that was previously available in the public endpoints has been removed.
  • Sorting behavior for patents whith inconsistently zero-padded IDs has been fixed.
  • The endpoint for "other references", previously inaccessible, has been fixed. The endpoint address has been corrected from "api/v1/patent/otherreference" to "api/v1/patent/other_reference" for consistency with other endpoints.
  • A bug preventing successful GET requests to the "ipc" endpoint has been corrected. Some POST requests may still produce internal errors.
  • The fields location_latitude and location_longitude in the "locations" endpoint, which were previously inaccessible, have been fixed.

Documentation Updates​

  • Documentation has been added for the updated text endpoints.
  • The expected json key for each endpoint has been added to the field list documentation on the reference page.
  • Several typos have been corrected.
  • Minor section ordering adjustments.
  • A social media preview image has been added to the documentation pages.

Naming Update​

PatentsView's Search API is now the PatentSearch API!
The new name was selected to improve the findability of the tool and better reflect both the API's purpose to provide patent data and the Elasticsearch technology that it leverages.
The naming used in existing documenation and release notes has been updated to reflect this name change and provide consistency.

Long text data notes​

  • The PatentSearch API now contains four new endpoints for long text data: brf_sum_text, claims, draw_desc_text and detail_desc text.
  • These endpoints are currently in beta phase. i.e. please expect the structure and dataset included to change over the next few releases
    • Currently, only 2023 data is available. Over the next few release, we'd be backfilling older data few years at a time. You can track the status on this page
  • Please see endpoint reference

Data update: 02/13/2024​

The PatentSearch API is updated to contain data through 12/31/2023.

Publication Endpoints​

Two new endpoints have been added.

  • /api/v1/publication : containting pregrant publication data
  • /api/v1/publication/rel_app_text: containing related application data for pregrant publications

See PatentSearch API Reference for field list reference

Documentation and User Resources​

The API Development team has developed a few resources for better communicating changes and updates relating to the PatentSearch API to users:

The users are, of course, always welcome to reach out via the PatentsView Help Center

Bug Fixes​

_contains operator​

Previously, the "_contains" operator

  • resulted in 500 server error if a list is supplied as the value.
  • produced incorrect results when the supplied value contained whitespaces.

This has been fixed and as a result of the fix the "contains" operator will now:

  • correctly account for spaces in the operator argument
  • permit lists as arguments (listed arguments will use "or" logic)

Other developer notes​

  • What's with v2.0?

    • Internally, the PatentsView team referred to the release that included pre-grant publications as v2.0 and the name stuck.

  • Does that mean the url will change?

    • No. We intend to keep the /api/v1 part of the API endpoint URLs as it stands.

  • What is happening with text data?

    • Because of its size, the long text data posed some challenges when integrating with the PatentSearch API. We are working to resolve those issues, and expect that text data will be available via the PatentSearch API within the next few releases.
