Glycol Dehydration Units Patents: Top Companies & Trends 2026
Glycol Dehydration Units Patents: Who Leads and Where the Gaps Sit
39.1% concentration. The five leading assignees hold 180 of the 460 records in scope — a top-heavy field with a long tail below them. The peak year so far is 2017 at 33 filings. Activity cooled afterward but rebuilt through the early 2020s: 2021 to 2024 filings doubled, from 5 to 10, before the expected reporting lag flattens the final two years of the chart.

Frequently asked questions
How many patents exist for glycol dehydration units?
This landscape covers 460 published patent families filed or published between 2015 and 2026 that match glycol dehydration and contactor-related search terms. The figure reflects records matching a specific search string tied to glycol contactors, water dew point, reboiler limits, stripping gas injection, glycol carryover and BTEX emission control, so a broader or narrower search string would return a different count. Treat this as the scope of the dataset rather than a definitive count of all glycol dehydration patents worldwide.
Who are the leading patent holders in glycol dehydration technology?
The assignee ranking covers 100 companies, with the leading filer holding 71 of the 460 records in scope and the top five combined holding 39.1%. That leaves a long tail of companies with only a handful of filings each, so the field has a dominant filer plus a wide base of smaller and occasional filers rather than a tight oligopoly. Names appear in the ranked table on this page rather than repeated here, since the exact order matters more than a summary list.
Is glycol dehydration patent filing activity increasing or slowing down?
Filings across the field doubled from 5 in 2021 to 10 in 2024, which is the clearest recent growth signal in the data. The peak year overall was 2017 at 33 filings, and activity cooled after that before rebuilding. Figures for 2025 and 2026 look lower, but that is expected: publication typically lags filing by about 18 months, so those years are still filling in rather than showing an actual decline.
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 Glycol Dehydration Units 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.
