Entity Resolution Patents: Who Leads, Where the Gaps Are 2026
Entity Resolution and Record Matching Patents: Who Files, Who Leads, and Where the Field Is Still Open
28.6% of all 248 records sit with just five assignees — concentrated at the top, but with 89 companies ranked in total, so a long tail is still filing. Filings rose from 7 in 2017 to a peak of 20 in 2021, then eased to 14 by 2024 — a -30% move across that three-year span. 2025 and 2026 figures are still incomplete because publication lags filing by roughly 18 months; treat the tail of the chart as a floor, not a ceiling.

Common questions about entity resolution patents
Who holds the most entity resolution patents?
Within this 248-record dataset, one assignee leads with 27 records, well ahead of the fifth-ranked holder at 9 and the tenth-ranked holder at 7. The top five assignees combined hold 71 records, or 28.6% of all records in scope, and the top ten hold 111, or 44.8%. That said, the ranking covers 89 companies in total, so most of the field sits in a long tail of firms with only a handful of filings each.
Is entity resolution patent filing growing or slowing?
Filing rose from 7 records in 2017 to a peak of 20 in 2021, then eased to 14 by 2024 — a -30% change across that three-year span. Because publication typically lags filing by around 18 months, the lower counts shown for 2025 and 2026 are incomplete rather than a real decline, and 2024 is the most recent year that can be read as a finished total. Treat any near-term dip in the chart with that lag in mind.
What technology areas do entity resolution patents fall under?
The dominant IPC subclass is G06F (electric digital data processing), covering 77.8% of the 248 records, followed by G06N (AI-model computing) at 27.8%. Smaller but notable shares fall in G06Q business-process claims (13.3%), G06K data recognition (8.5%), and healthcare informatics G16H (6.5%). Because a record can carry multiple IPC classes, these figures add up to more than 100% of the record total, which is expected.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Entity Resolution and Record Matching covering 2015–2026, data cut-off 2026-07-31.
