CAES System State Monitoring Patent Snapshot 2026
The patent corpus for CAES system state monitoring is extremely sparse, with only 1 patent family in scope, held entirely by Vardhaman College of Engineering and filed in India in 2024. The field is effectively pre-competitive at the patent level, signalling that technical activity — if it exists — has not yet translated into formal IP filings.
One filer holds the entirety of the indexed corpus
Vardhaman College of Engineering is the sole ranked applicant, holding all 1 patent family currently indexed for CAES system state monitoring. With a top-five share of 100% of the ranked applicants visible in this query’ combined total — in this case a corpus of one — there is no meaningful competition at the patent level today.
There are no tier gaps to speak of: the ranking consists of a single entry, and no corporate assignees, national laboratories, or industry incumbents appear in the dataset.

This level of sparsity implies that either the technology is being developed without formal IP protection, that relevant work is filed under different classification terminology, or that the field is genuinely nascent.
The single 2024 filing may be under-counted relative to its eventual citation and family footprint due to the typical 18-to-24-month publication lag; the true activity level may be modestly higher than the index currently reflects.
Activity is effectively zero prior to 2024; technology mix spans turbines, boilers, and gas separation
The annual filing trend and IPC composition together reveal a field with no recorded patent activity before 2024 and a narrow but technically coherent set of classification anchors.
Annual filing trend
Zero filings appear across 2017–2023; the sole family emerged in 2024. The 2025–2026 bars show zero, consistent with expected publication lag for very recent applications rather than confirmed absence of activity.

The single family spans three IPC branches — F02C (gas-turbine plants), F22B (steam generation and boilers), and F25J (gas liquefaction and separation) — reflecting the multi-system scope typical of compressed-air energy storage integration monitoring.

Harnessing Adiabatic Compressed Air Storage (A-CAS) for Renewable Electrification System is the proposed invention. The utility model introduces a compressed air energy storage system designed for renewable source-based electrification systems. It consists of a charging subsystem and a discharging subsystem. In the charging subsystem, intake air is filtered… (excerpt from the patent abstract)

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.
Vardhaman College of Engineering
Vardhaman College of Engineering holds the only indexed patent family in this topic, filed in 2024, marking it as a new entrant (momentum trend: new entrant). Its technology emphasis covers F02C 6 and F02C 7 (gas-turbine plant configurations) and F22B 1 (steam generation and boilers), consistent with a systems-integration or monitoring architecture spanning multiple CAES subsystems.
families: 1No second-ranked filer identified
No challenger or second-tier applicant appears in the current corpus. Any organisation filing a first patent family in CAES system state monitoring would immediately become the co-leader in the indexed landscape.
families: —Frequently asked questions
The current indexed corpus contains 1 patent family, filed in India in 2024. This is an extremely small corpus and should be interpreted as a signal that formal IP activity in this specific topic has barely begun.
Vardhaman College of Engineering is the sole ranked applicant, holding all 1 patent family in the indexed corpus. It is an academic institution based in India, and no commercial or industrial assignees appear in the dataset.
India is the only jurisdiction in the current dataset, with 1 patent record filed there. No PCT, EPO, USPTO, CNIPA, or other national-phase counterparts have been indexed, leaving major energy markets without formal coverage.
The single family spans F02C (gas-turbine plants), F22B (steam generation and boilers), and F25J (gas liquefaction and separation), reflecting a systems-level scope across multiple CAES subsystems.
Based on the available evidence — a single filing appearing for the first time in 2024 with no prior-year activity — the field is at an embryonic or pre-competitive stage. No life-cycle stage can be formally assigned from the current corpus size.
F17C (pressure vessel and gas storage containers) and G01M (machine testing and condition monitoring) are adjacent branches absent from the current corpus. Both are directly relevant to CAES monitoring architectures — pressure-cycle management and real-time diagnostics respectively — and neither appears to have been claimed in this topic area yet.

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.
