Knowledge Graph Construction Patents: Who Leads, Trends 2026
Knowledge Graph Construction Patents: Mapping Who Files, Where and What They Claim
Concentration is modest. the top 5 assignees hold 220 records, just 22.4% of the 983 in scope, and the top 10 add up to only 30.9% — no single filer controls the field. Annual filings rose from 40 in 2017 to a peak of 101 in 2025. The only complete-year comparison available, 2021 to 2024, shows a 29% drop in filings across that span. Because publication lags filing by roughly 18 months, the 2025 and 2026 figures are still filling in and should not be read as a rebound.

Common questions about knowledge graph construction patents
Who holds the most patents in knowledge graph construction?
The ranked list covers 100 assignees, and the leader holds 73 of the 983 records in scope. The top 5 combined account for 220 records, or 22.4% of the field, and the top 10 add up to 30.9%. That leaves the majority of filings spread across a long tail of smaller and single-filing entrants, so leadership by volume does not translate into control of the technology space.
Is patent filing for knowledge graph construction growing or slowing?
Filings rose from 40 in 2017 to a peak of 101 in 2025, but the only complete year-over-year window available, 2021 to 2024, shows a 29% decline in annual filings. Publication lags actual filing by roughly 18 months, so the apparent 2025 peak likely reflects earlier applications finally publishing rather than a renewed surge. Treat the 2025-2026 figures as provisional until later data confirms the direction.
What patent classes cover knowledge graph construction technology?
The dominant classes are G06F (electric digital data processing, 79.5% of the 983 records) and G06N (AI-based computing, 37.0%), reflecting that most claims are framed as general computing or machine-learning methods. G06Q (business data processing) appears in 19.5% of records. Domain-specific classes such as G16H (healthcare informatics, 2.5%) and G06K (data recognition, 2.4%) are comparatively rare, marking them as less crowded areas for new filings.
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.
