Chromatographic Fingerprinting for Quality Control: Where the Patents Concentrate
Filing peaked in 2021 at 27 records, then eased to 22 by 2024 — a -19% shift over that span, not a collapse of interest. Filings rose from 18 in 2017 to a peak of 27 in 2021, then eased to 22 by 2024, a -19% change over that three-year span. 2025 and 2026 figures are still partial: publication lags filing by roughly 18 months, so the most recent two years will fill in as later publications are indexed.

Common questions about this patent set
What counts as a chromatographic fingerprinting patent for quality control?
In this dataset, it means a filing describing how a chromatogram is built, validated and used to confirm batch-to-batch consistency of a formulated product, typically through similarity evaluation, reference-chromatogram comparison, peak assignment or chemometric analysis. Nearly all 213 records in scope fall under IPC subclass G01N, covering material analysis and testing, which confirms the field is defined by analytical method claims rather than by the drug substance itself. A smaller share also touches A61K or A61P where the fingerprint method is tied to a specific medicinal preparation or therapeutic use.
Who are the leading patent holders in chromatographic fingerprinting?
Filing is concentrated among traditional Chinese medicine manufacturers and research institutes rather than instrument makers. The top-ranked assignee holds 21 records, well ahead of the fifth-place holder at 7 and tenth place at 5, and the top 5 assignees together account for 30.0% of all 213 records in scope. Beyond the top 10, which holds 45.1% combined, the field has a long tail of entrants with one or two filings each, often tied to a single named product.
Is chromatographic fingerprinting patent activity growing or declining?
Filings rose from 18 in 2017 to a peak of 27 in 2021, then eased to 22 by 2024, a -19% change over that three-year span. That is a real pullback from the peak but not a collapse, since 22 filings a year is still close to the 2017 level. The 2025 and 2026 figures shown in any trend chart will understate true activity because publication typically lags filing by around 18 months.
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.
