Demand Response Patents: Who Leads, Where the Gaps Are 2026
Demand response program design patents: mapping notification, rebound and baseline control claims
Concentrated at the top. The top 5 assignees hold 376 of 592 records in scope (63.5%), and the top 10 hold 79.2% — a narrow group has shaped how load curtailment and rebound-effect claims are written. Annual filings peaked at 42 in 2017. On the last complete comparison window, 2021's 21 filings fell to 10 by 2024 — a 52% decline. Years 2025 and 2026 show far lower counts, but that reflects publication lag rather than a stalled field; do not read the tail as a trend on its own.

Common questions on demand response program design patents
Who holds the most patents in demand response program design?
One assignee leads the ranked field with 237 of the 592 records in scope, well ahead of the fifth-ranked assignee at 26 records. The top 5 assignees combined hold 63.5% of all records, and the top 10 hold 79.2%, so leadership in this field is concentrated rather than evenly spread across the 85 ranked companies. Anyone assessing competitive position should look closely at the leader’s specific claim scope rather than assuming the field is fragmented.
Is demand response patent filing growing or declining?
Filings peaked in 2017 at 42 for the year and have declined since; on the last window comparable across complete years, filings fell from 21 in 2021 to 10 in 2024, a 52% drop. Figures for 2025 and 2026 are much lower still, but publication typically lags filing by about 18 months, so those recent years are undercounted rather than genuinely near zero. The honest read is a real pullback from 2017’s peak through 2024, with the very latest years still uncertain.
What technology areas do demand response patents cover?
The dataset spans eight IPC subclasses, led by H02J power supply and grid systems at 61.3% of the 592 records. Digital transmission (H04L), control and regulating systems (G05B), business-process data handling (G06Q) and electric variable control (G05F) each appear in roughly a quarter of records, showing that most filings combine grid-side hardware with a software or control layer. Air conditioning and ventilation (F24F) is the narrowest tracked class at 11.0%, marking HVAC-specific load control as a smaller niche within the broader field.
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.
