Nano Drilling Fluids Patent Snapshot 2026
The indexed corpus for nano drilling fluids currently stands at a single patent family, filed by Baker Hughes Oilfield Operations LLC via PCT in 2020, indicating an extremely nascent or narrowly indexed space with no observable competitive dynamics. Activity peaked in 2020 and has since returned to zero, consistent with a field that has not yet attracted broad applicant participation.
Baker Hughes holds the only indexed position in a minimally active field
Baker Hughes Oilfield Operations LLC is the sole ranked applicant, holding the single patent family within the current corpus — giving it full representation among the ranked applicants visible in this query.
With one applicant accounting for all activity, there is no meaningful tier structure or competitive distribution to describe; the field as indexed presents no second-tier challengers.

Baker Hughes’ singular position reflects either very early-stage commercial interest, a narrow search scope, or limited public disclosure activity in nano drilling fluids to date — not necessarily a consolidated competitive moat.
The most recent periods in any patent corpus tend to be under-counted due to publication lag of 18–24 months; absence of filings after 2020 in this data should be interpreted with that caveat in mind. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single filing peak in 2020 with no subsequent indexed activity
The annual filing trend reveals a one-time pulse in 2020, with no indexed filings in any surrounding year. The technology composition is split equally across materials science and earth-drilling IPC classes.
Annual filing trend
One patent family was filed in 2020; all other years in the window show zero activity. Years from 2023 onward are subject to publication lag and should not be read as confirmed absence of filings.

The single family maps to two IPC branches in equal measure — C09K (materials for miscellaneous applications) and E21B (earth and rock drilling, wells) — reflecting the dual nature of nano drilling fluid innovation at the interface of chemistry and downhole engineering.

A method for operating in a borehole comprises disposing in a downhole environment an article comprising a bismaleimide composite which comprises a polybismaleimide and a disintegrating agent; exposing the article to an aqueous fluid at a temperature of about 25oC to about 300oC; and disintegrating the article.

Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Baker Hughes Oilfield Operations LLC
Baker Hughes Oilfield Operations LLC holds the single indexed patent family in nano drilling fluids, covering IPC branches C09K8 (materials for miscellaneous applications), E21B33, and E21B43 (earth and rock drilling). Applicant momentum data is not available in the current evidence, so trajectory beyond the 2020 filing cannot be confirmed from this corpus alone.
families: 1No challenger identified
No second-ranked applicant exists in the indexed corpus. The absence of challengers reflects the minimal size of the current dataset rather than a definitive assignee snapshot. Broader searches may surface additional applicants not captured here.
families: N/AFrequently asked questions
The indexed corpus contains one patent family. This is an unusually small dataset and may reflect narrow search parameters or limited public disclosure in this specific sub-field to date.
Baker Hughes Oilfield Operations LLC is the only indexed applicant, holding the single patent family filed via WIPO (PCT) in 2020.
The single indexed family maps to C09K (materials for miscellaneous applications) and E21B (earth and rock drilling, wells), specifically sub-classes E21B33 and E21B43, reflecting the intersection of drilling chemistry and wellbore engineering.
The lifecycle classification is Decline, with annual filings easing back from the 2020 peak. However, given the corpus contains only one family, this classification carries low statistical confidence and should be supplemented with broader database searches.
The sole patent family was filed through WIPO (PCT). National phase entry jurisdictions, which would indicate the specific commercial markets being targeted, are not visible in the current indexed data.
No co-applicant or collaboration relationships are identified in the indexed corpus. Baker Hughes Oilfield Operations LLC appears as a solo filer on the single indexed family.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
