Turbofan Nano-Coating / CMC Patent Snapshot 2026
The current indexed corpus for turbofan nano-coating and CMC is extremely early-stage, with a single patent family on record filed by Siemens Energy Global GmbH & Co KG in 2022 under the UK jurisdiction. Concentration is absolute at this corpus size, and the field cannot yet be characterised for competitive dynamics — it represents either a highly specialised niche or an early signal of emerging activity.
Single filer defines the entire indexed corpus
Siemens Energy Global GmbH & Co KG is the sole ranked applicant in the current corpus, holding the only patent family on record in this intersection of turbofan nano-coating and ceramic matrix composite (CMC) technology.
With one applicant accounting for the entirety of the ranked applicants visible in this query’ combined total, there is no tier gap to analyse — the field is at its earliest measurable stage and meaningful concentration metrics will only emerge as additional applicants enter.

Siemens Energy’s position as sole filer signals either a proprietary focus on a narrow technical niche or that broader industry activity in this specific combination is not yet captured in this corpus.
The corpus covers approximately the last ten years; recent periods are subject to publication lag and may under-represent the true current state of filings. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single filing in 2022 defines all observable activity
The annual filing trend and technology composition both reflect the minimal corpus size: one family filed in 2022 under a single IPC branch, with no other years recording activity.
Annual filing trend
All indexed activity is concentrated in 2022, when the sole patent family was filed. Years 2017–2021 and 2023–2026 show no recorded filings; the absence of post-2022 filings is consistent with publication lag and should not be read as confirmed inactivity.

The entire corpus falls under C23C (Coating and surface deposition), specifically C23C 4, indicating that the indexed work addresses deposition processes for coatings rather than CMC bulk material or propulsion system design branches.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
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.
Siemens Energy Global GmbH & Co KG
Siemens Energy Global GmbH & Co KG holds the only indexed patent family in this corpus, filed in 2022 and classified under C23C 4 (coating and surface deposition). Its applicant momentum is recorded as a new entrant with one recent filing against no prior-period baseline, indicating this is an initial staking of IP rather than an established programme. The UK filing jurisdiction aligns with Siemens Energy’s European gas turbine manufacturing footprint.
families: 1No challenger on record
No second-ranked applicant exists in the current corpus. An engineer monitoring this space should set up forward citation alerts on GB2625083A and broaden search scope to related nano-coating or CMC classifications to identify potential entrants not yet captured in this specific query.
families: N/AFrequently asked questions
The current corpus contains 1 patent family in scope. This is an extremely small evidence base, and engineers should treat it as an early signal requiring broader search validation before drawing strategic conclusions.
Siemens Energy Global GmbH & Co KG is the sole ranked applicant, holding the only indexed patent family. It is recorded as a new entrant with one recent filing and no prior-period baseline.
The single family is filed in the United Kingdom. No parallel filings in other major patent offices — such as the US, European Patent Office, China, or Japan — are currently indexed for this specific query.
The entire corpus falls under C23C — specifically C23C 4, covering coating and surface deposition processes. No CMC bulk-material (C04B) or turbine component design (F02C) branches are present in the current evidence.
A life-cycle stage cannot be determined from the current evidence. The corpus is too small — one family filed in 2022 — to characterise the field as nascent, growth, or mature. Additional filings and a broader query scope are needed before a meaningful life-cycle assessment is possible.
No co-applicant relationships are recorded in the current evidence. This is consistent with having a single patent family in the corpus. Ecosystem or academic-industry partnership patterns cannot be assessed at this stage.

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.
