Single-Use Bioreactor Gas Transfer Patents: Who Holds the Claims
51.8% concentration. The top five assignees alone account for 260 of the 502 records in scope — over half the field sits with a handful of holders. Filings ran from 43 in 2017 to a peak of 60 in 2023. The tracked growth window shows 2021 at 27 filings falling to 10 in 2024 — a 63% drop over that three-year span. Because publication trails filing by roughly 18 months, 2025 and 2026 figures are still incomplete and should not be read as a continued decline.

Questions practitioners ask about this space
Who holds the most patents in single-use bioreactor gas transfer?
The assignee ranking behind this dataset covers 100 companies, with a single leader holding 90 of the 502 records in scope. The top five combined account for 260 records, or 51.8% of the field, and the top ten extend that to 72.5%. That leaves a long tail of smaller filers holding the remaining records individually or in small clusters.
Is patent filing in this area growing or slowing down?
Filing volume peaked at 60 records in 2023 after rising from 43 in 2017. The most reliable growth read is the 2021-to-2024 window, which shows a 63% decline from 27 to 10 filings. Figures for 2025 and 2026 are still incomplete because publication typically lags actual filing by around 18 months, so it is too early to call the most recent years a continued slowdown.
What technical areas do single-use bioreactor gas transfer patents actually cover?
Every record in this scope carries a C12M bioreactor classification, but most also overlap with adjacent areas: B01F mixing and stirring appears in 18.7% of the 502 records, C12N microorganism and genetic engineering in 12.7%, and C07K peptide and protein claims in 11.8%. Separation processes under B01D show up in 11.2% of records. This overlap means most claims bundle the gas-transfer mechanism with agitation hardware or the biological process it serves, rather than filing gas transfer alone.
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 Single-Use Bioreactor Gas Transfer 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.
