Differential Privacy in Training Patents: Leaders & Trends 2026
Differential Privacy in Training Patents: Who Leads and Where Claim Space Is Still Open
Concentration is moderate, not extreme. the top 5 assignees hold 40.7% of all 118 records in scope, and the top 10 hold 55.9% — meaningful headroom sits outside the leading names. Filings began from zero in 2017 and reached a peak of 33 in 2025, with 19 already recorded in 2026 despite the year being incomplete. The last full-year comparison — 11 records in 2021 versus 22 in 2024, a +100% increase — is the growth figure to cite; 2025 and 2026 will keep rising in the record as later publications land, since publication typically lags filing by around 18 months.

Common questions about this landscape
How many patents exist for differential privacy in training?
This landscape covers 118 published records filed or published between 2015 and the 2026-07-31 data cut-off. The figure includes applications and granted patents across all receiving offices tracked in this search, so it represents documented filing activity rather than a count of only granted rights. Because publication lags filing by roughly 18 months, the most recent one to two years will keep growing as pending applications surface.
Who are the leading companies filing differential privacy patents?
The ranking spans 100 companies counted by record, with the top assignee holding 14 records against 6 for fifth place and just 2 for tenth place — a steep early drop-off. The top 5 assignees combined account for 40.7% of all 118 records, and the top 10 account for 55.9%, meaning a leader exists but more than half the field’s filings sit outside the top 10. Company names are available in the full ranking rather than summarised here, since a hand-picked list would misrepresent how quickly the concentration thins out.
Is differential privacy patent filing activity growing or slowing?
Filings roughly doubled from 11 in 2021 to 22 in 2024, a +100% increase over that three-year span, which is the most reliable growth read available since 2024 is the last year publication lag allows to be treated as complete. Later years — 33 in 2025 and 19 so far in 2026 — look higher still, but should not yet be read as a definitive peak or decline, since 2025-2026 filings are still publishing. Any claim that the field is slowing based on 2025 or 2026 numbers alone would be premature.
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.
