Airlift Bioreactor Vessel Design Patents: Leaders & Filing Trends 2026
Airlift Bioreactor Vessel Design Patents: Who Holds the Vessel Claims
84.5% concentration. The top five assignees account for 60 of the 71 records in scope, leaving a thin tail of single- or double-filing entrants. Filings peaked in 2017 at 19 records. The 2021-to-2024 window shows genuine growth, rising from 1 to 3 filings, a 200% increase across that span. Years after 2024 should be read as still filling in rather than as a real drop-off.

Common questions on airlift bioreactor vessel design patents
Who holds the most patents on airlift bioreactor vessel design?
One assignee leads the ranked field with 19 of the 71 records in scope, well ahead of the fifth-ranked holder at 4 records. The top five assignees combined account for 84.5% of all records, and the top ten reach 95.8%, so filing activity in this niche is heavily concentrated rather than spread evenly across many companies. Anyone assessing freedom to operate should look closely at that leader’s claim scope before assuming open ground.
Is filing activity in airlift bioreactor design growing or slowing down?
The raw yearly count looks like it peaked in 2017 and thinned out afterward, but that is misleading on its own. Looking specifically at 2021 to 2024, filings grew 200%, and because publication lags actual filing by roughly 18 months, the apparent drop in 2025 and 2026 mostly reflects records that have not published yet rather than a real pullback in R&D. Treat 2024 as the most recent year with a reasonably complete count.
What IPC classes should I search alongside C12M for this technology?
In this dataset, 46.5% of the 71 records also carry a C12N class for microorganisms and genetic engineering, and 26.8% carry either A01N (biocides/agrochemicals) or C05F (organic fertilisers). B01F for mixing and stirring appears on 19.7% of records. Since a single record can carry several IPC codes, these shares do not need to add to 100%, and searching only C12M in isolation will miss a large share of relevant filings.
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 Airlift Bioreactor Vessel Design 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.
