Online Process Gas Chromatography Patents: Leaders & Trends 2026
Online Process Gas Chromatography Patents: Who Leads and Where the Field Is Still Open
Concentrated at the top. The top 5 assignees hold 92 of 148 records in scope (62.2%), and the top 10 hold 82.4% — a small group of filers controls most of the documented claim space. Filings rose from 0 in 2017 to a peak of 9 in 2019, then declined; the last complete comparison point runs from 5 filings in 2021 to 0 in 2024, a -100% change. Years after 2024 are still filling in as publications catch up with filing dates, so treat 2025 and 2026 counts as provisional rather than as evidence of a further drop.

Common questions about this field
Who holds the most patents in online process gas chromatography?
The ranked assignee list of 40 companies shows a single leader with 37 of the 148 records in scope, well ahead of the fifth-ranked assignee at 9 and the tenth-ranked at 5. The top 5 assignees together hold 62.2% of all records, and the top 10 hold 82.4%, so the field is heavily concentrated rather than evenly spread. Anyone assessing competitive position should look closely at the leader’s granted claims first, since they cover the largest single share of the documented art.
Is patent filing activity in this field growing or shrinking?
Filings peaked at 9 in 2019 and then declined; the clearest complete comparison runs from 5 filings in 2021 to 0 in 2024, a -100% change over that span. Because publication typically lags filing by around 18 months, 2025 and 2026 figures are still incomplete and should not be read as confirmation of further decline. On the evidence available through 2024, the field’s filing activity has clearly cooled from its 2019 high point.
What technology areas overlap most with online process gas chromatography patents?
Material analysis and testing (IPC class G01N) appears on 42.6% of the 148 records, and addition polymer chemistry (C08F) appears on 27.7%, making these the two dominant classification areas. Control and regulating systems (G05B), electron and discharge tubes (H01J), and catalysis-related processes (B01J) follow at lower shares. This mix confirms that a large portion of filings in the space are tied to polymer reactor control rather than general laboratory chromatography.
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 Online Process Gas Chromatography 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.
