Thermal Treatment of Drilling Waste Patents: Who Leads 2026
Thermal Treatment of Drilling Waste: patents, filers and where the field is thin
Four ranked assignees account for all 13 records in scope, with the leader alone holding 10 — this is a field defined by a single dominant filer rather than a crowded competitive set. Filings are concentrated in a single peak year of 2017, with 10 of the 13 records in scope published that year and no ranked filings recorded in the years since — consistent with an early wave of claims that has not been followed by a second one.

Common questions on this landscape
Who holds the most patents on thermal treatment of drilling waste?
In this dataset of 13 records, one assignee holds 10 of them, with the remaining three records split across three other ranked assignees. That makes this a concentrated field with a single dominant filer rather than several competing portfolios of similar size. Anyone assessing freedom-to-operate should focus first on that leading assignee’s claims before looking at the smaller filers.
When did patent filing on this technology peak?
Filing activity peaked in 2017, when 10 of the 13 records in scope were filed, and no ranked filings have been recorded in the years since through the 2026 data cut-off. Because publication typically lags filing by around 18 months, the most recent years understate true activity, but the gap since 2017 is large enough to suggest a genuine slowdown rather than just a reporting delay.
What technology areas are most heavily claimed within drilling waste thermal treatment?
Separation processes classified under B01D appear in 69.2% of the 13 records, and centrifuge technology under B04B appears in 38.5%, making these the two most densely claimed technical areas. Soil and contaminated-land reclamation (B09C) follows at 23.1%. Drying (F26B), hydrocarbon refining (C10G), earth drilling (E21B) and water treatment (C02F) each appear in only a single record, indicating much lighter claim coverage on the thermal and drying side of the process.
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 Thermal Treatment of Drilling Waste covering 2015–2026, data cut-off 2026-07-31.
