Bacterial chassis transporter engineering patents: who holds the uptake and export claims
41.9% sits with five filers. The top 5 assignees hold 143 of 341 records in scope, so freedom-to-operate work should start with their claim sets, not a broad novelty search. Filings ran from 22 in 2017 to a peak of 24 in 2020, then declined to 1 by 2024 (-95% from the 2021 level of 22); 2025-2026 figures are still incomplete under the publication lag and should not yet be read as a trend reversal or confirmation.

Common questions on this landscape
Who are the leading patent holders in bacterial chassis transporter engineering?
One assignee leads with 62 of the 341 records in scope, well ahead of the fifth-ranked filer at 20. The top 5 assignees together hold 143 records, or 41.9% of the field, and the top 10 hold 214 records, or 62.8%. That leaves a long tail of smaller filers holding the remaining share, so a full competitive picture requires looking past just the largest names.
Is patent filing activity in this space growing or slowing?
Filings peaked in 2020 at 24 and fell to 1 by 2024, a -95% drop from the 2021 level of 22. Because publication lags filing by around 18 months, 2025 and 2026 figures are still incomplete and should not be treated as confirmation of a continued decline. Based on the last complete year, 2024, filing activity in this exact claim scope has thinned substantially from its 2020-2021 peak.
What technology areas dominate the IPC classification of these patents?
C12N, covering microorganisms and genetic engineering, appears in 84.8% of the 341 records, making it the dominant classification by a wide margin. A61K medicinal preparations follow at 46.0%, with C12Q measurement methods, C07K peptides and proteins, and C12P fermentation each near 28%. Because a single record can carry several IPC classes, these percentages do not sum to 100% and should be read as independent shares of the same 341-record base.
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 Bacterial Chassis Transporter Engineering 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.
