ASHP Fault Detection & Diagnosis Patent Snapshot
The formal patent corpus for air-source heat pump fault detection and diagnosis contains only 3 patent families on record, all assigned to a single applicant — Venaera Inc — in 2024. The space is effectively at its earliest formation stage, with no established concentration pattern and a wide open field for additional entrants.
A single first-mover holds every ranked family
Venaera Inc holds all 3 patent families currently ranked in this corpus, making it the sole documented innovator in the formal patent record for ASHP fault detection and diagnosis.
Venaera Inc accounts for 100% of the top hundred ranked filers’ combined total — an extreme concentration that reflects an embryonic field rather than an entrenched monopoly. No second- or third-tier applicant has yet appeared in the record.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Venaera Inc | 3 |
Venaera Inc’s position implies first-mover advantage in filing, but with only 3 patent families the protective perimeter is narrow. The absence of any other applicant signals that major HVAC OEMs, diagnostics software firms, and research institutions have not yet staked formal patent claims in this exact sub-field.
Because patent applications typically publish 12–18 months after filing, activity from late 2024 and 2025 may not yet be fully visible in the record; the corpus should be treated as a minimum bound rather than a complete picture.
All filings concentrated in 2024; refrigeration IPC class leads
The annual filing trend shows zero activity from 2017 through 2023, with all 3 patent families appearing in 2024. The technology composition is split between two IPC classes aligned to heat-pump and air-conditioning systems.
Annual filing trend
All 3 families were filed in 2024, marking the field’s first recorded year of activity. The 2025 and 2026 bars show zero, but given standard publication lag those years remain under-counted and cannot be read as an absence of new filings.

Two of the three families fall under F25B (Refrigeration & heat pumps), and one under F24F (Air conditioning & ventilation), indicating that diagnostic claims are anchored in refrigerant-cycle monitoring rather than purely in building-controls software.

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.
Venaera Inc
Venaera Inc holds all 3 patent families in the corpus, with claims spread across F25B 49 (refrigeration and heat pumps, 2 families), F24F 11 (air conditioning controls, 1 family), and F24F 13 (air conditioning components, 1 family). Its momentum is characterized as a new entrant — all activity originated in 2024, the first year of recorded filing in this niche. Representative published applications include US20240318852A1, US20240318878A1, and WO2024197187A1.
families: 3No challenger identified
No second-ranked applicant appears in the current corpus. The challenger position is vacant, presenting an open lane for any HVAC OEM, diagnostics software company, or research institution that files in this space. Evidence on emerging challengers will only become available as additional applications publish.
families: —Frequently asked questions
The current corpus contains 3 patent families on record. All three were filed in 2024, making this a very early-stage niche with limited prior art to navigate.
Venaera Inc is the only applicant in the ranked corpus, holding all 3 patent families. It entered as a new entrant in 2024 with no prior filing history in this specific sub-field visible in the record.
The documented corpus spans two classes: F25B (Refrigeration & heat pumps), which covers 2 of the 3 families, and F24F (Air conditioning & ventilation), which covers 1 family. Sub-classes F25B 49, F24F 11, and F24F 13 are specifically represented.
Two of the three patent families are filed in the United States, and one has been filed via WIPO (PCT), enabling potential international extension. No European, Chinese, or other national filings appear in the current record.
All recorded activity occurred in 2024. No filings appear from 2017 through 2023, and the 2025–2026 data remains subject to publication lag. It is too early to characterize a growth trajectory; the field is at its formation stage.
Three representative applications are on record: US20240318852A1 and US20240318878A1 (both US national-phase publications) and WO2024197187A1 (PCT application), all assigned to Venaera Inc.

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.
