What's Coming
We are adding patent data from India to the LexisNexis® PatentSight+™ Dataset. The release is planned for the 9th November. 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 1.395 million families with at least one Indian member. Indian documents and family members will be included, and metrics that depend on family membership, such as Market Coverage, will reflect them.
This release covers bibliographic data, including IPC classifications and available legal events. Claims, descriptions, images, OCR and machine translations will not be included; full text, where available, comes via existing LexisNexis sources.
Other data products will not be 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 data
- Broader coverage. Around 1.8 million Indian documents will be added, including Indian-only inventions.
- More complete families. Existing families will gain any Indian members. Technology Relevance (TR) will also shift 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.
- 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. Some Indian legal status events are received and mapped to the PatentSight+ legal status logic. Where possible, legal events are given a WIPO ST.27 code.
Fields not available for Indian patents
Citation data, CPC and F-Terms will not be 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 F-Terms if they include a member from an office that uses them.
Family identifiers
Families with a DOCDB/EPO simple family ID (sfam_ID) keep it. Where there is none, LexisNexis will assign 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.
FAQs
Do I need to do anything?
No activation is required to access the added India coverage. You can continue using your existing PatentSight+ search and portfolio workflows.
Which data products include the Indian data?
Indian patent data is being added to the LexisNexis® PatentSight+™ Dataset. Other Data Products are not affected by this release.
What does 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 1.395 million families with at least one Indian member. The Dataset provides harmonized patent families, supported ownership mapping, and metrics such as Patent Asset Index (PAI).
When will the data appear?
India coverage is scheduled to be added on 9 November 2026. After that, Indian records 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.
Will values in the data I already use change?
They may. 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.
