Streaming Feature Computation Patents: Who Files, What They Claim
Filings are concentrated but not locked down. the top 5 assignees account for 43.9% of all 57 records in scope, while a long tail of single-filing entrants holds the rest. Annual filings rose from 2 in 2017 to a peak of 18 in 2025, but the only year-over-year comparison the data can support without publication-lag distortion is 2021 to 2024, where filings dropped 56% (9 to 4). 2025 and 2026 counts will keep rising as later-filed applications publish, so treat the apparent peak with caution rather than reading it as renewed momentum.

Frequently asked questions
What is streaming feature computation in the context of patents?
It refers to the technical field of computing model-ready features from continuous data streams close to real time, rather than in periodic batch jobs. Patent activity in this space typically covers sliding-window aggregation, feature backfill for late-arriving data, and mechanisms to keep training-time and serving-time feature values consistent. This dataset draws its 57 records from a search string that pairs pipeline or serving terms with consistency or freshness terms, which is why the results skew toward infrastructure and data-handling claims rather than pure model-architecture claims.
Who are the leading patent filers in streaming feature computation?
The assignee ranking covers 61 companies counted in records, with the leader holding 11 of the 57 records in scope and a steep drop to 3 records by fifth place. That pattern — one clear leader, a closely matched mid tier, and a long tail of single-filing entrants — means competitive screening should prioritise the double-digit holders rather than trying to track the full ranked list. Several of the historically active names show no filings in the latest year, which given publication lag may reflect pipeline delay rather than an actual stop.
Is patent filing in this field growing or slowing down?
The reliable comparison is 2021 to 2024, where filings fell 56% (from 9 to 4), and that is the only year-over-year figure in this dataset that avoids publication-lag distortion. Later years, including a nominal peak of 18 filings in 2025, will keep revising upward as more applications publish, since publication typically lags filing by around 18 months. Read the field as having pulled back from an earlier peak through 2024, with the true trajectory since then still unresolved.
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 Streaming Feature Computation 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.
