Ranking Model Patents: Who Leads, Where the Gaps Are 2026
Ranking Models and Feature Interaction Patents: who holds the claim space
Concentrated at the top. The leading assignee alone holds 38 of 221 records, and the top five together account for 44.8% of all records in scope. Annual filings rose from 4 in 2017 to a peak of 44 in 2022, then eased to 22 by 2024 — a -12% change over the 2021-2024 span. 2025 and 2026 figures are still incomplete due to publication lag and should not be read as a decline.

Common questions about this landscape
Who holds the most patents on ranking models and feature interaction?
Filing is concentrated at the top: the leading assignee alone accounts for 38 of the 221 records in scope, and the top five combined account for 44.8% of all records. The tenth-ranked assignee holds only 5 records, which shows a fast drop-off from the leader to the rest of a 68-company ranked field. This concentration means a small number of portfolios shape the core claim space around CTR estimation and feature crossing, while the remaining companies each hold a handful of filings in narrower niches.
Is patent filing in this field growing or slowing down?
Filings rose steadily from 4 in 2017 to a peak of 44 in 2022, then eased to 22 by 2024, a -12% change over that three-year span. That is a real signal for the most recent complete years, but 2025 and 2026 figures are still incomplete because publication typically lags filing by about 18 months. Treat the 2022 peak as the high point so far rather than assuming the field is now shrinking.
Which technology areas get the most patent claims in ranking and feature interaction?
G06F (electric digital data processing) covers 62.4% of the 221 records and G06N (AI-based computing) covers 59.3%, making these the two dominant classification areas. G06Q (business and commerce data processing) follows at 30.3%, tying many filings to specific commercial contexts like advertising or e-commerce ranking. Smaller classes such as G06V (image/video recognition) and H04L (digital transmission) sit in single digits, marking areas with comparatively less claim density.
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 Ranking Models and Feature Interaction covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
