Change Data Capture Patents: Top Companies & Filing Trends 2026
Change Data Capture Pipeline Patents: Who Files, What They Claim, and Where Gaps Remain
Concentrated at the top. Five companies hold 58.9% of the 594 records in scope, and ten hold 75.4% — a narrow set of assignees shapes nearly the whole field. Annual filings ran from 34 in 2017 up to a peak of 77 in 2019, then eased down; the 2021-to-2024 span, the most recent period with complete data, shows a 31% decline from 64 to 44 filings. 2025 and 2026 figures are still filling in and should not be read as a continued fall.

Common questions on CDC pipeline patents
Who holds the most patents on change data capture technology?
The ranking covers 67 assignees, with the leader holding 114 of the 594 records in scope — more than double the fifth-place total of 38. The top five combined account for 58.9% of all records, and the top ten reach 75.4%, so a small group of database and cloud infrastructure vendors controls most of the documented claim space. Anyone entering this field should expect to file around positions already held by these leaders rather than into open ground.
Is patent filing activity in change data capture growing or slowing?
Filings peaked at 77 in 2019 and, over the most recent complete period, fell from 64 in 2021 to 44 in 2024, a 31% decline. That pattern looks more like a maturing core mechanism than an abandoned one, since foundational techniques like log-based replication and snapshot handling were largely staked out in the earlier peak years. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so they should not be read as a continued drop.
What does US11899659B2 actually cover?
US11899659B2, assigned to Amazon Technologies and granted 2024-02-13, covers dynamically adjusting the performance of materialized view maintenance in response to monitored update performance and changes in the target data store’s capacity to receive updates. It is framed around a materialized view management platform that scales its update behaviour to handle data source changes and target outages. For anyone building adaptive materialized-view refresh logic, this claim scope is worth checking closely before finalising an implementation.
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 Change Data Capture Pipelines 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.
