Bulk Gas & Nitrogen Supply Patents: Top Companies & Trends 2026
Bulk Gas and Nitrogen Supply System Patents
Concentrated at the top. The five leading assignees combined hold 42.4% of all 278 records in scope, and the ranked ten hold 63.7% — a field where a handful of filers set the terms for valve and purge claims. Filings rose from 2 in 2017 to a peak of 20 in 2019, then settled into a lower band. The tracked three-year comparison shows 2021's 6 records against 2024's 5, a -17% change — the most reliable recent-trend read available, since 2025 and 2026 are still incomplete under normal publication lag.

Common questions on bulk gas supply system patents
Who are the leading patent holders in bulk gas and nitrogen supply systems?
The dataset ranks 73 companies by patent family count across 278 records, with the leading assignee holding 34 records against a fifth-place figure of 15 and a tenth-place figure of 10. That gap shows a field led by a single dominant filer rather than a tightly bunched top tier. The full ranking, rather than any single name, is the more reliable signal since filing counts shift as new publications are added each year.
What technology areas get the most patent activity in this space?
Valve and tap claims under IPC class F16K appear on 27.3% of the 278 records, the single densest category, followed by control-of-non-electric-variables claims under G05D at 19.4%. Coating and surface deposition (C23C) and pressure vessel and gas storage (F17C) claims follow behind those two. Because a single record can carry multiple IPC classes, these percentages overlap rather than summing to a whole field breakdown.
Is patent filing in bulk gas supply systems growing or slowing down?
Filings peaked at 20 in 2019 and have settled lower since; the most reliable recent comparison shows 2021’s 6 records dropping to 2024’s 5, a -17% change over that span. Figures for 2025 and 2026 are still incomplete because patent publication typically lags the actual filing date by around 18 months, so those years should not yet be read as confirming a continued decline. The honest read is a cooling from peak activity rather than a sharp collapse.
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 Bulk Gas and Nitrogen Supply Systems 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.
