Photobioreactor Scale-Up Patents: Leaders, Trends & White Space 2026
Photobioreactor scale-up patents: who holds the engineering claims and where the field is still open
35.9% concentration at the top. The five leading assignees hold 93 of 259 records in scope, but the next tier thins out fast into single- and double-filer entrants. Filings rose from 15 records in 2017 to a peak of 24 in 2023, then settled at 15 in 2024 — a -6% move from 2021's 16 records. Treat 2025 and 2026 as undercounts: publication typically lags filing by around 18 months, so the most recent two years will keep filling in.

Common questions on photobioreactor scale-up patents
How many companies hold patents in photobioreactor scale-up?
The ranking behind this dataset covers 97 companies across 259 published records. The field is concentrated at the top: the five leading assignees together hold 93 records, or 35.9% of all records in scope, while the tenth-ranked assignee holds only 7. Below that tenth position there is a long tail of entrants with just one or two filings each, so most named organisations in this space are not repeat filers.
Is photobioreactor patent filing activity growing or slowing down?
Filing volume peaked so far at 24 records in 2023 and moved from 16 records in 2021 to 15 in 2024, a -6% change over that span — essentially flat rather than a clear decline. Counts for 2025 and 2026 look lower, but publication typically lags filing by about 18 months, so those recent years are undercounted and should not be read as a slowdown. A fair read is that filing has plateaued after a mid-2020s peak, not that interest has dropped.
What patent classes cover photobioreactor scale-up technology?
The two dominant IPC subclasses are C12N (microorganisms and genetic engineering), covering 64.5% of the 259 records, and C12M (bioreactors and enzyme apparatus), covering 61.8%. Because records can carry multiple classes, these figures overlap heavily, showing most scale-up claims are filed jointly with organism or culture-condition claims rather than as standalone mechanical apparatus filings. Water treatment (C02F) and fermentation (C12P) each cover roughly a third of records, with separation processes (B01D) a comparatively thin 6.2%.
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 Photobioreactor Scale-Up 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.
