Hydrocarbon Dew Point Control Patents: Leaders & White Space 2026
Hydrocarbon Dew Point Control Patents: Who Holds the Claims
Concentrated at the top. The five most active filers hold 93 of 154 records in scope (60.4%), and the top ten hold 81.2% — a narrow group of assignees controls most of the documented claim space. Filings peaked at 15 records in 2019 and have not returned to that level since; the final one or two years in the chart are understated because publication trails filing by roughly 18 months, so a flat or falling recent line should not be read as declining interest.

Frequently asked questions
Who holds the most patents in hydrocarbon dew point control?
One assignee leads the field with 43 of the 154 records in scope, well ahead of the fifth-place company at 9 records. The ranking covers 37 companies in total, and the top five combined hold 60.4% of all records, so filing activity is concentrated rather than evenly spread. Anyone assessing freedom-to-operate should look closely at the leader’s claim scope before drafting in the mechanical separation or valve space.
What technologies are covered by hydrocarbon dew point control patents?
The dataset spans low-temperature separators, Joule-Thomson valves, mechanical refrigeration chillers, hydrate inhibitors, condensate stabilisation and adsorbent-based dehydration. By IPC subclass, gas liquefaction and separation (F25J) and general separation processes (B01D) each cover roughly a quarter of the 154 records, with valves (F16K), hydrocarbon refining (C10G) and fuel compositions (C10L) also well represented. Materials-specific claims under C09K are comparatively less common, at 13.6% of records.
Is hydrocarbon dew point control patent filing growing or slowing?
The filing trend peaked in 2019 at 15 records and has not returned to that level in the years since. A reliable growth rate cannot be stated from the years available, because fewer than four complete years remain once the roughly 18-month publication lag is accounted for. The most recent one to two years in any chart should be read as undercounted rather than as evidence of a slowdown.
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 Hydrocarbon Dew Point Control 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.
