Release 8.3

15 February 2022 by Aaron Ballagh in Release Notes

Release 8.3
Introducing Non-APC Journals filter, ROR integration, new Lens Support Centre, improved Legal Status calculations and more!

New Features and Improvements

Non-APC Journals 'Diamond OA' filter

With this release we have added a filter for Non-APC Journals, which are open access journals that do not charge Article Processing Fees (APCs), also known as 'Diamond OA' journals. Sourced from DOAJ, there are over 4.6M scholarly works in Diamond OA journals in The Lens. For more information on Non-APC Journals, please see the OA Diamond Journals Study.

ROR Integration

With the retirement of the Global Research Identifier Database (GRID) from the public space, the Research Organization Registry (ROR) has replaced GRID as a community-driven institutional database.

A final dataset has been released along with a ROR-to-GRID mapping to facilitate the transition to ROR institution identifiers and location information, and ROR has now been integrated into The Lens. The ROR identifier and location information is available through the following new fields:

  • Institution ROR ID (author.affiliation.ror_id)
  • Institution City (
  • Institution State (author.affiliation.address.state_code)
  • Institution Country/Region (author.affiliation.address.country_code)
  • Institution Type (author.affiliation.type)

These fields replace the equivalent GRID fields, which will be deprecated in future. Users should not notice any changes in the meantime and legacy GRID fields will remain active for some time to allow users to transition to using ROR.

Legal Status Calculation Improvements

The following improvements were made to the calculation of Legal Status and Granted Dates for patents:

  • If no legal status event exists in INPADOC, the DOCDB publication reference is used to calculate the granted status.
  • Improvements to the document-key mapping logic have improved the number of patent records with granted status.
  • If an INPADOC legal status event exists, but there is no grant date for the grant event, the improved document key mapping logic is now used to identify the grant date for calculation of legal status.

New Support Centre & Knowledge Base

Lens Support Center & Knowledge Base

Introducing the new Lens Support Centre & Knowledge Base! Now out of beta, you can access the new support site from within the Lens platform to explore new support material, online tutorials and videos to discover the many features has to offer and how you can get the most out of these. A new Support Sidebar is also available including all new support content, which can be searched from within the sidebar. Support search results include a pop-out modal that features the support post video if one is available, allowing users to quickly and easily find and view support content right from within the Lens. The support header menu has also been updated with an added link to the API documentation. We are continually adding new support material, videos, tutorials and use cases to help you make the most of The Lens tools and features.

Other Improvements and Changes

The Lens is a work in progress and with each release, the Lens team improves on certain features or perfects the quality of the data and the service to provide you with the most comprehensive data we can source. While often these changes stem from users' feedback, they also originate from improved data processing and improvements in the source data. In this release, here is the list of other improvements and changes that were implemented:

  • Added lookup by country/jurisdiction name search and auto-suggest in the structured search page for the Inventor Country, Applicant Country, Owner Country and Agent Country fields.
  • Added a new scholar field "Original Affiliation" (author.affiliation.name_original) containing the author's original affiliation as listed on the scholarly work, including the institution name and address. e.g. "School of Engineering and Applied Sciences, Harvard University, Cambridge, Massachusetts USA"


  • Fix sort order for patent exports
  • Fix JSON file export failing
  • Added missing export fields to the JSONL export file, including:
    • Patent exports: biblio.parties.applicants.residence, inventor.residence, applicant.residence
    • Scholar exports: source.asjc_subject, patent_citations.lens_id
  • Fix for patent records with Inactive Legal Status that were not reviving to Active in some cases when a fee paid event occurs subsequent to the patent termination date.
  • Fix handling of user Notes on deleted patent documents. If a note has been added to a patent document which is then deleted, the Notes tab no longer fails.
  • Fix for patent date filters submitted from the homepage search, only one date type filter can be applied at a time.
  • Fix routing error from Collective Action to Lens Labs
  • Fix return to previously viewed scholarly work/patent list item anchor on reslit pages >1
  • Changed the renewal email reminder period for 2-week trial API plans so users don't get a reminder email until it has expired.

API & Data Improvements:

  • API: Added maxResultPerPage subscription plan parameter to the API usage endpoints.
  • Scholarly Works: Added new request fields: author.affiliation.ror_id, author.affiliation.name_original, source.is_diamond,, author.affiliation.address.state_code, author.affiliation.address.country_code, author.affiliation.type, has_affiliation_ror, and new response field: authors.affiliations.ids. Updated to the latest OpenCitations Index of Crossref open DOI-to-DOI citations (COCI) dataset, dated 29 January 2022.
  • PatSeq: Fix document key mapping logic to extract additional WO sequence listings previously missed.
