Biological Safety Cabinets Patents: Who Leads, Where the Gaps Are 2026
Biological Safety Cabinet and Isolator Patents: Filing Trends and Leading Assignees
One assignee leads with 14 records, while the fifth-ranked holder has just 3 and the tenth has 1 — a short head over a long tail of single-filing entrants. Filings rose from zero in 2017 to a peak of 5 in 2023. Measured against the last complete year, 2021's 2 filings fell to 1 by 2024 — a 50% decline over that three-year span. 2025 and 2026 figures will revise upward as publication catches up.

Common questions about this landscape
Who holds the most patents on biological safety cabinets and isolators?
One assignee leads this dataset with 14 records, well ahead of the rest of the field; the fifth-ranked holder has only 3 and the tenth has 1. That leader’s filings concentrate on chlorine dioxide and vapour-phase decontamination hardware, which also shows up among the most-cited records in the dataset. The remaining ranked assignees, including several individual inventors who co-file together, hold much smaller, narrower positions.
Is patent filing in biological safety cabinets and isolators growing or slowing?
Filing peaked at 5 records in 2023 and, measured on the last complete year available, fell 50% from 2021’s count of 2 to 2024’s count of 1. Counts for 2025 and 2026 are still incomplete because publication typically lags filing by about 18 months, so it is too early to call the current trend a genuine slowdown. The more reliable read is that activity has been modest and uneven rather than steadily rising.
What technology areas dominate biological safety cabinet patents?
Sterilising and disinfecting technology, IPC class A61L, appears in 54.3% of the 35 records in scope, making it the single largest technology area by a wide margin. Control systems (G05D) and chemical or physical process claims (B01J) each cover about a quarter of records, while cleaning hardware (B08B) and packaging (B65B) cover smaller shares. Robotics (B25J) and radiation shielding (G21F) are the thinnest areas, each present in only 8.6% of records.
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 Biological Safety Cabinets and Isolators 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.
