Sequencing Flow Cell Patents: Who Leads, Where the Gaps Are 2026
Sequencing flow cell and surface chemistry patents: mapping who controls cluster generation and imaging
86.8% concentration. The top five assignees combined hold 2,067 of all 2,380 records in scope — filing here is not fragmented, it is a small group defending a large footprint. Filings rose from 78 in 2017 to a peak of 329 in 2020, then declined -54% from 287 in 2021 to 133 in 2024 — the last year with complete publication data. 2025 and 2026 figures (13 in the most recent year) are still filling in and should not be read as a continued decline.

Common questions about this landscape
Who holds the most patents in sequencing flow cell technology?
One assignee holds 1,163 of the 2,380 records in this dataset, and together the top five combined reach 2,067 records — 86.8% of the field. That concentration is heavier among a cluster of related entities filing under closely linked corporate names, several of which appear together as co-assignees on the same families. Anyone assessing freedom to operate in this space should start with those top few portfolios rather than treating the field as fragmented.
Is patent filing in sequencing flow cells still growing?
No — filings peaked at 329 records in 2020 and have since declined, falling -54% from 287 in 2021 to 133 in 2024, the last year with complete publication data. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so they should not yet be read as continued decline or as a floor. The trend is a genuine cooling from a 2020 high, not an artefact of missing recent data alone.
What technology areas do these patents actually cover?
Most records — 72.3% of the 2,380 in scope — fall under IPC class C12Q, covering enzyme- and DNA-based measuring and testing methods central to cluster generation and sequencing chemistry. Smaller but still substantial shares touch microorganism and genetic engineering methods (C12N, 16.1%), bioinformatics (G16B, 14.5%) and material analysis (G01N, 13.5%). Because a single record can carry several IPC classes, these percentages add up to more than 100%, and narrower classes like polymer chemistry (C08F) or combinatorial libraries (C40B) sit under 10%, marking them as comparatively open ground.
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 Sequencing Flow Cells and Surface Chemistry 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.
