Powder Flowability Characterization Patents: Who Holds the Core Claims
22.9% concentration at the top. The top 5 assignees hold 473 of 2,069 records in scope, but the ranked field runs 100 companies deep with a long tail of single-digit filers. Filings ran from 96 in 2017 to a peak of 99 in 2020, then eased to 82 in 2021. The 2021-2024 span moved from 82 to 80 filings, a -2% shift — essentially flat rather than declining. The falloff visible in 2025-2026 is a publication-lag artefact, not evidence of slowing interest.

Common questions about this landscape
What patents dominate powder flowability characterization?
The most-cited records in this field are older spray-drying and particulate-delivery patents, including filings on perforated microparticles and particulate delivery systems, rather than recent test-instrumentation patents. Citation counts favour age, so these anchors reflect long-standing influence rather than current filing activity. Newer entrants tend to build formulation or device claims that reference flow-property thresholds set by this earlier work rather than filing on the measurement method itself.
Who are the leading assignees in powder flowability patents?
Filing is moderately concentrated: the top five assignees together hold 22.9% of the 2,069 records in scope, and the top ten hold 32.5%. One assignee leads clearly ahead of the rest of the ranked field of 100 companies, but the drop from second to tenth place is gradual rather than a sharp cliff, meaning several companies maintain sustained filing programmes without any single firm locking down the space.
Is the powder flowability patent field growing or shrinking?
Filings peaked at 99 in 2020 and have since settled into a near-flat pattern, moving from 82 in 2021 to 80 in 2024 — a -2% change over that span, essentially stable rather than declining. Figures for 2025 and 2026 look lower, but that reflects the roughly 18-month lag between filing and publication, not a genuine drop in activity. Any trend read from the two most recent years alone would be misleading.
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 Powder Flowability Characterization covering 2015–2026, data cut-off 2026-07-31.
