Filamentous Fungi Promoter Patents: Top Filers & Trends 2026
Filamentous Fungi Promoter Engineering Patents: Who Leads and Where Filing Is Headed
Concentrated at the top. The five leading assignees together hold 41.4% of all 1,835 records in scope, with a further tail of single- and low-filing entrants. Filings climbed from 34 records in 2017 to a peak of 53 in 2019, then eased back; the 2021-to-2024 span shows a 40% decline (42 to 25 records), the last year clean of publication-lag distortion.

Common questions on this landscape
Who holds the most patents in filamentous fungi promoter engineering?
One assignee leads clearly with 238 records, well ahead of fifth place at 81 and tenth place at 34 in the ranked list. The top five assignees combined hold 41.4% of all 1,835 records in scope, and the top ten hold 52.1% combined. Beyond that, filing counts drop off quickly into a long tail of firms with only a handful of records each, so due diligence should focus first on the leading handful of portfolios.
Is patent filing in this field growing or slowing down?
Filings rose from 34 records in 2017 to a peak of 53 in 2019, then declined; the 2021-to-2024 window (the last span with complete data) shows a 40% drop, from 42 to 25 records. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by about 18 months, so it is too early to call the most recent years a continued decline. The honest read is a maturing filing pace after a 2019 peak, not a collapse.
What technology areas dominate the IPC classification of these patents?
C12N, covering microorganisms and genetic engineering, appears in 97.3% of the 1,835 records, confirming this is fundamentally a host-cell engineering field. C12P (fermentation and enzymatic synthesis) and C07K (peptides and proteins) each appear in roughly a third of records, reflecting the strong overlap with enzyme production. Because records can carry multiple IPC codes, these percentages add up to more than 100% and should not be summed.
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.
