Compact / Monobloc ASHP Patent Snapshot 2026
The compact and monobloc air-source heat pump space is a small but rapidly growing field, with filing activity up 80% in the recent window and the corpus still in a growth stage. Octopus Energy Heating Ltd holds the largest individual position, yet the overall patent evidence snapshot is nascent, leaving meaningful room for new entrants across both Western and Chinese markets.
Octopus Energy Heating leads a highly concentrated but still-small field
Octopus Energy Heating Ltd ranks first among all applicants, holding the largest individual block of patent records in this corpus. The top five filers together account for 80% of the combined total across the ranked applicants visible in this query, signalling a field where a handful of organisations have established early positions.
Despite that concentration ratio, the absolute scale of the corpus remains limited, meaning that even the leading applicant’s portfolio is modest by mature-technology standards. The gap between the top-ranked filer and the cluster immediately below is meaningful but not prohibitive for challengers.

The leadership positions of Chinese manufacturers — Hisense Hitachi, Midea’s two filing entities, and Beijing Huahong Huanneng — alongside a UK-based energy retailer suggest two distinct strategic logics: integrated product engineering on one side and system-level heating-service innovation on the other.
The most recent 18–24 months of filings are likely under-counted due to patent publication lag; reported totals for 2024–2025 should be treated as minimums. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity is rising and dominated by air-conditioning and refrigeration classes
Two views of the corpus — annual filing cadence and IPC class composition — together show a field that only emerged meaningfully from 2019 onward and is concentrated in a narrow set of thermal-engineering branches.
Annual filing trend
Filings were negligible before 2019, grew intermittently through 2022, and reached a multi-year high in 2024. The 2025 and 2026 bars reflect publication lag and will revise upward; the growth-stage characterisation is therefore robust.

F24F (air conditioning and ventilation) is the visible branch, followed by F25B (refrigeration and heat pumps) and F24D (domestic heating systems). F24H (fluid and water heaters), D06F (laundering and drying), and F22B (steam generation) each carry a small share, highlighting adjacencies that remain lightly explored.

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.
Octopus Energy Heating Ltd
Octopus Energy Heating Ltd holds 5 patent records — the largest individual position in the corpus. Its technology focus spans F24F 11 (air conditioning controls and ventilation management), F24D 19 (domestic heating systems), and F24H 15 (fluid and water heaters), reflecting a system-level, consumer-facing approach. Momentum is flagged as a new entrant, indicating all recent filings are concentrated in the current period with no prior-period base — a sign of deliberate, rapid portfolio construction rather than organic accumulation.
5 patent recordsShenzhen Ouruibo Electronics
Shenzhen Ouruibo Electronics holds 3 patent records, with emphasis on F25B 41 (refrigeration cycle components), F24F 1 (unitary air conditioning), and F24F 13 (air-handling components) — a hardware-oriented profile distinct from Octopus Energy Heating’s controls focus. Momentum is also flagged as a new entrant, confirming that all activity is recent. Qingdao Hisense Hitachi Air Conditioning Systems and Beijing Huahong Huanneng each hold 3 patent records as well, making this a three-way tie for second position.
3 patent recordsFrequently asked questions
The corpus in scope contains 15 patent families. This is a small, early-stage dataset reflecting a technology that only began generating consistent filings from 2019 onward.
Octopus Energy Heating Ltd holds the top position with 5 patent records — the largest individual block in the corpus. Qingdao Hisense Hitachi Air Conditioning Systems, Shenzhen Ouruibo Electronics, and Beijing Huahong Huanneng Technology each hold 3 patent records.
China is the leading jurisdiction by patent-record count, followed at a distance by the United States and a spread of single-record filings across Europe (EPO), Australia, Spain, Austria, New Zealand, and WIPO (PCT).
The evidence characterises compact/monobloc ASHP as a growth-stage technology. Annual filings are still rising, and the most recent years are likely understated due to publication lag, so the 80% recent-window growth figure should be treated as a conservative indicator.
The only confirmed co-applicant relationship is between Guangdong Midea Heating & Ventilating Equipment Co. Ltd and Hefei Midea Heating & Ventilating Equipment, which have co-filed 2 patent records. This is an intra-group arrangement; no cross-company or industry-academic collaboration has been observed at scale.
The two sparsest branches are D06F (laundering, drying and ironing) and F22B (steam generation and boilers), each with 2 patent records and a 6% share. Both are adjacent to core ASHP technology and have been explored only by Beijing University of Civil Engineering and Architecture, leaving them open to commercial entrants.
