Building Energy Management Patents: Who Leads and Where Filing Is Headed
35.6% concentration at the top. The five leading assignees together account for 3,585 of the 10,070 records in scope — a field with a clear head and a long tail below it. Annual filings ran from 686 records in 2017 up to a peak of 961 in 2019, then eased to 552 by 2024 — a -35% move across the 2021-2024 window. 2025 and 2026 numbers will keep revising upward as publication catches up with filing, roughly an 18-month lag, so treat the tail of the chart as a floor rather than a ceiling.

Common questions about building energy management patents
Who are the leading patent holders in building energy management?
The dataset's assignee ranking is led by a single company holding 1,728 of the 10,070 records in scope, well ahead of the fifth-ranked holder at 321 and the tenth at 136. The top five assignees together account for 35.6% of all records, and the top ten reach 46.2%, so the field has a genuinely concentrated head even though the ranking itself covers 100 companies rather than a handful. For competitive tracking, the leader's portfolio matters more than any single rival's.
Is building energy management patent filing growing or slowing down?
Filing peaked at 961 records in 2019 and has since declined, falling from 849 in 2021 to 552 in 2024 — a -35% move over that three-year span. That is the last window that can be read as a real trend, because publication lags filing by roughly 18 months and the 2025-2026 figures are still incomplete. Read the recent apparent drop-off with that caveat rather than as confirmed slowing.
What technology areas dominate building energy management patents?
Control and regulating systems (IPC class G05B) appear in 36.3% of the 10,070 records, the single largest technical class, ahead of air conditioning and ventilation hardware (F24F) at 22.6%. Business and administrative data processing and general digital data processing each sit around 18%, and AI-based computing already reaches 6.5%. Because a single patent can carry several IPC classes, these figures describe overlapping claim territory rather than mutually exclusive buckets, and together they show the field's centre of gravity sitting in control software rather than mechanical HVAC equipment.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
