Coriolis Mass Flow Meter Patents: Top Companies & Trends 2026
Coriolis mass flow meter patents: who holds the claim space and where it is still open
Concentrated at the top. the five leading assignees together account for 51.5% of all 4,810 records in scope, and the top ten hold 57.8%. Filings rose to a peak of 194 in 2020, then eased; the 2021-to-2024 window fell 42%, from 96 to 56 records. Treat 2025 and 2026 figures as undercounted rather than as evidence of a further drop.

Common questions about this landscape
Who holds the most Coriolis mass flow meter patents?
The assignee ranking in this dataset is led by a single company with 1,818 of the 4,810 records in scope, well ahead of the fifth-place holder at 121 records. The top five assignees together hold 51.5% of all records, and the top ten hold 57.8%, so the field is concentrated at the top with a long tail of smaller filers below that. Anyone assessing freedom to operate should check the leader’s portfolio first, since it dwarfs every other applicant in the ranking.
Is Coriolis mass flow meter patent filing growing or slowing down?
Filing peaked at 194 records in 2020 and has declined since; the last complete three-year window shows a 42% drop, from 96 records in 2021 to 56 in 2024. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by about 18 months, so they should not yet be read as continued decline. The honest read is that volume has cooled from its 2020 high, not that the technology area is inactive.
What technical problems dominate Coriolis mass flow meter claims?
The search scope combines core Coriolis measurement language with specific problems: tube vibration, density measurement, two-phase flow, zero stability, pressure drop and installation stress. The IPC data shows 69.3% of records sit in G01F, the flow, level and volume measurement subclass, confirming that most claims address the core sensing mechanism rather than downstream applications. Material analysis (G01N) is a distant second at 19.9%, and every other class sits under 6%.
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 Coriolis Mass Flow Meters 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.
