Smart / IoT Heat Pump Patent Snapshot 2026
The Smart / IoT Heat Pump patent corpus is extremely small and highly concentrated, with activity peaking in 2019 and easing since then. Shandong Santu Energy Co., Ltd. holds the largest position, with Venaera Inc. as the only other identified filer, and filings are concentrated in China with a secondary US presence.
A nascent, highly concentrated field with minimal competition
The corpus contains just 3 patent families in scope. Shandong Santu Energy Co., Ltd. ranks first with 2 patent families, while Venaera Inc. holds 1 patent family — together accounting for the entirety of the top applicant pool.
The top five filers’ share of the ranked applicants visible in this query is 100%, indicating there is no meaningful second tier; this is an extremely concentrated field with effectively only two identifiable filers.
| # | Applicant | Patent families | Share |

China, while Venaera Inc. represents the sole US-based participant. The field’s tiny scale means any new entrant could materially reshape the assignee snapshot.
The most recent 18–24 months of filings are subject to publication lag and may undercount actual activity; the apparent absence of 2024–2026 filings should be treated cautiously. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single early peak in 2019 with no sustained follow-on activity
Filing activity in this topic spiked briefly in 2019 and has not re-accelerated since. The technology composition is anchored in air-conditioning and ventilation control, with a secondary signal in electrical measurement.
Annual filing trend
Two families were filed in 2019, representing the field’s peak. A single family appeared in 2024, with no recorded activity in the intervening years. Years from 2024 onward are subject to publication lag and should not be read as a confirmed absence of filings.

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.
Shandong Santu Energy Co., Ltd.
Holds 2 patent families, all filed around the 2019 peak. Technology emphasis is split evenly between F24F 11 (air-conditioning and ventilation control) and G01R 21 (electric and magnetic measurement), reflecting an integrated approach to IoT-connected heat pump monitoring. No applicant momentum data is available for recent filings, suggesting activity has been dormant since the peak year.
families: 2Venaera Inc.
Holds 1 patent family and is flagged as a new entrant, with its filing recorded in 2024. Technology focus covers both F24F 11 and F24F 13 (air-conditioning and ventilation sub-systems), indicating a broader HVAC system scope than the leader’s monitoring-centric portfolio. As the sole US-jurisdiction filer, Venaera Inc.’s trajectory warrants continued monitoring.
families: 1Frequently asked questions
The corpus contains 3 patent families in scope, making this a very early-stage or narrowly defined topic with limited prior art to navigate.
Shandong Santu Energy Co., Ltd. leads with 2 patent families, followed by Venaera Inc. with 1 patent family. These two applicants represent the entire identified corpus.
China accounts for 2 patent records and the United States accounts for 1. No other jurisdictions are represented in the current corpus.
The field is assessed as being in a Decline stage: annual filings peaked in 2019 and have eased back since, with only a single family recorded in 2024. The recent-period data is subject to publication lag.
F24F (air conditioning and ventilation) covers all 3 families and is the primary class. G01R (electric and magnetic measurement) appears in 2 families, reflecting the remote monitoring and sensing aspect of IoT-connected systems.
No co-applicant relationships are recorded in the current dataset. Both filers appear to have pursued IP independently, and no joint assignee filings are present.

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.
