ASHP LCA & Low-GWP Refrigerant Patent Snapshot
The intersection of air-source heat pump life-cycle assessment and low-GWP refrigerants contains only 2 patent families in scope, filed in 2025 by two individual inventors across Australia and Canada. The field is nascent and effectively uncontested by corporate or institutional players.
Two individual inventors hold the entirety of this nascent space
The corpus stands at just 2 patent families, with Tyler J. Olson and Brian R. Workman as the only identified filers. Together they account for the full activity captured in this search.
There is no meaningful tier structure: both inventors hold equivalent positions with 1 patent record each among the top-ranked filers. No corporate, academic, or institutional applicant appears in the ranking.

The absence of established HVAC or refrigerant manufacturers signals that formal IP competition in the combined ASHP life-cycle assessment and low-GWP refrigerant space has not yet begun at an organizational level.
All activity appears concentrated in a single filing year (2025), and given standard publication lag of 18–24 months, the full scope of recent filings may not yet be visible. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
All activity compressed into a single year, spanning two IPC classes
The annual trend and technology composition charts together reveal a field that emerged in 2025 with no prior recorded filings and a tight, dual-class IPC footprint.
Annual filing trend
Zero filings are recorded from 2017 through 2024; both patent records appear in 2025. The 2025 figure should be treated as a lower bound given publication lag — additional 2025 filings may not yet be published.

Described herein is a ventilation system for a building that includes an air source heat pump and an exhaust plenum system. The air source heat pump may include a compressor, a condenser, a reversing valve, and an evaporator. The exhaust plenum system is configured to mix building infrastructure exhaust airflow with an ambient airflow to provide an exhaust-… (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.
Tyler J. Olson
Tyler J. Olson holds 1 patent record, focused on F24F 12 (heat recovery ventilation), F24F 7 (air supply/exhaust), and F25B 27 (heat pumps using waste heat). Filed in 2025 in Australia, with no prior-period activity against which to assess momentum.
patent records: 1Brian R. Workman
Brian R. Workman holds 1 patent record with an identical IPC focus: F24F 12, F24F 7, and F25B 27. Filed in 2025 in Canada. The parallel technical scope suggests the two inventors may be co-inventors on a jointly conceived but separately filed application, though no formal co-applicant relationship is recorded.
patent records: 1Frequently asked questions
The corpus contains 2 patent families in scope, both filed in 2025. No prior-year activity is recorded between 2017 and 2024.
No corporate or institutional applicants appear in the ranking. The only documented filers are two individual inventors: Tyler J. Olson and Brian R. Workman, each holding 1 patent record.
One patent record is filed in Australia and one in Canada. No filings are recorded in the United States, European Patent Office, China, Japan, or other major heat pump markets.
Both patent records are classified under F24F (air conditioning and ventilation) and F25B (refrigeration and heat pumps), specifically subclasses F24F 12, F24F 7, and F25B 27.
A life-cycle stage cannot be determined from only 2 patent families. All activity is concentrated in 2025, and additional filings from that year may not yet have cleared the publication lag window of 18–24 months.
The most observable gaps relative to the existing corpus are in F25B 13 (heat pump cycle design for space heating with low-GWP working fluids) and F24F 11 (control systems integrating real-time LCA optimization). Major geographic markets including the US, EU, and China are entirely uncovered by current filings.

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.
