What's New
We have added patent data from India to the LexisNexis® PatentSight+™ Dataset. India is the world’s sixth largest patent jurisdiction, and this release adds around 1.8 million bibliographic documents (applications, granted patents and designs), covering approximately 1.4 million families with at least one Indian member.
Around 600,000 of these are new families, almost all India-only, and around 700,000 to 800,000 existing families gained Indian documents. Indian documents and family members are included, and metrics that depend on family membership, such as Market Coverage, reflect them. The release covers bibliographic data, including IPC classifications and available legal events. Claims, descriptions, images, OCR and machine translations are not included; full text, where available, comes via existing LexisNexis sources.
Other data products are not affected by this release. The LexisNexis® PatentSight+™ Dataset uses the same underlying data as the LexisNexis® PatentSight+™ platform, so the Indian data is included in both.
What this means for your analysis
- Broader coverage. Around 1.8 million Indian documents have been added, including Indiaonly inventions. Depending on your export, Indian design registrations may also appear. They are handled in the same way as design registrations from other countries.
- More complete families. Existing families now include any Indian members, and family-level details, such as applicant or owner lists, may have grown. Technology Relevance (TR) has also shifted slightly, including for patents with no Indian members, because TR is a relative benchmark against all other patents. The change is small, usually less than the movement seen in a typical weekly update, though in rare cases it may be larger.
- Expanded portfolio analysis. Competitor and geographic portfolio views now reflect the Indian data.
- Annuity fees. Annuity fee calculations use Indian patent office rates. The Indian data includes fee payment information and dates.
Coverage and Limitations
Legal status
India is treated as an untrusted authority in the PatentSight+ Dataset, because the legal event data we receive is not sufficient to establish a reliable status on its own. Available Indian legal events are mapped to the PatentSight+ legal status logic and are visible at the document level. Where possible, legal events are given a WIPO ST.27 code. In the PatentSight+ platform, open the legal status viewer by selecting the in force / pending / inactive button at the top right of the family in the Results Sheet.
Fields not available for Indian patents
Citation data, CPC and F-Terms are not provided for Indian patents. Where another patent cites an Indian patent, that citation is captured through the usual data route. Families may carry CPC or FTerms if they include a member from an office that uses them. India-only families therefore have no values for these fields.
Family identifiers
Families with a DOCDB/EPO simple family ID (sfam_ID) keep it. Where there is none, LexisNexis assigns an ID in its own format (an integer, for example 121418383). This keeps the data consistent with earlier PatentSight+ data and other systems that use the DOCDB/EPO ID. The DOCDB/EPO family ID can no longer be used as a proxy for the LexisNexis family ID, or the reverse. To find a family, search by Publication Number or Application ID instead.
If you load the Dataset into your own systems
If you load the PatentSight+ Dataset into your own systems, check the following points in deliveries from 9 November 2026 onwards. The LexisNexis PatentSight+ Dataset India Patent Export Guide covers each one in more detail.
- Identify Indian records. Indian publications carry the country code IN in the country or authority column, and their publication numbers start with IN. The kind code shows the document type, for example IN 716KO2005 A for a published application and IN 289449 S for a design registration. Filter on IN to isolate or exclude Indian data.
- Distinguish family types. Group publications by family ID. If every publication in a family has the country code IN, it is an India-only family: it has a new family ID and all its rows are new to you. If a family has IN plus at least one other country code, it is a mixed family: it keeps its family ID, gains Indian rows, and its family-level lists and indicators may change. Compare mixed families with your previous delivery to identify new Indian documents.
- Storage and load limits. Files are up to about 2% larger. Most files have about 0.6% to 1.7% more rows.
- Incremental or delta loads. Expect updates to rows you already hold, such as longer applicant lists on mixed families. These are expected changes, not errors.
- New family IDs. Make sure your process accepts new family IDs. About 600,000 new families have been added.
- Joins on EPO family ID. If you link records using the DOCDB/EPO family ID as though it were the LexisNexis family ID, switch to the publication number or application ID.
- Legal status filters. Filtering to active families may exclude Indian patents that are still active in India.
- Reports and dashboards. Counts by country, family or owner rise where India is included, and new Indian owners, such as universities and research institutes, appear. Use the country code IN to separate Indian records when comparing deliveries.
- CPC, F-Terms and citations. India-only families have no values for these fields. Plan for empty fields.
FAQs
Do I need to do anything?
No activation is required. The Indian data is available in both the PatentSight+ Dataset and the PatentSight+ platform, and you can continue using your existing search and portfolio workflows. If you load the Dataset into your own systems, check the points in “If you load the Dataset into your own systems”: files are slightly larger, include new family IDs, and some existing rows have changed.
Which data products include the Indian data?
Indian patent data has been added to the LexisNexis® PatentSight+™ Dataset and is also available in the PatentSight+ platform. Other data products are not affected by this release.
What did the update add to the Dataset?
Approximately 1.8 million Indian bibliographic documents covering patent applications, granted patents and designs, including India-only inventions and Indian members of international patent families. In PatentSight+, this represents approximately 1.4 million families with at least one Indian member, around 600,000 of which are new families. The Dataset provides harmonized patent families, supported ownership mapping, and metrics such as Patent Asset Index (PAI).
When is the data available?
India coverage was added on Monday, 9 November 2026. Indian records now arrive through a weekly feed: data is collected on Fridays, delivered to LexisNexis between Monday and Wednesday of the following week, and expected to be available in the second calendar week after collection. For delivery options for your own systems, contact us.
To discuss your requirements, contact your customer success manager or Support.
How can I identify Indian records in my data?
Indian publications carry the country code IN, and their publication numbers start with IN. Filter on IN to isolate or exclude Indian data. To identify families affected by the update, use the family ID together with the country code.
Why does an organization sometimes appear in the inventor name field?
In a small number of Indian records, the inventor name field contains an organization name. This comes from the source Indian data, which we represent faithfully in the inventor field. It also matches how the record appears on InPASS, the Indian Patent Office’s search system.
Have values in the data I already use changed?
They may have. Market Coverage and dependent indicators, including PAI, can change where Indian members qualify as active, and adding Indian members does not automatically increase every score. Technology Relevance (TR) is measured against the whole patent population, so it can change for families without Indian members as well. If you load the Dataset into your own systems, expect new records and some changes to existing family-level values. Differences may reflect the expanded data as well as changes in patent activity.
What is not included for Indian records?
This is bibliographic data, with IPC classifications and available legal events. Claims, descriptions, images, OCR and machine translations are not included. Native backward citation data is not provided, although citations from foreign patents to Indian documents can be captured through existing data routes. The Indian Patent Office does not assign CPC classifications or Japanese F-Terms, though a family may carry them through members from offices that use them.
How should I treat the legal status of Indian members?
Available Indian legal events are mapped to PatentSight+ legal status logic, and where possible are given a WIPO ST.27 code. An inactive family does not necessarily mean that every Indian member has expired, so filtering to active families may exclude patents that are still active in India.
