Virtual Power Plant Demand Response Patents: Who Leads 2026
Virtual Power Plant Demand Response Patents
China dominates the filing base. 412 of 521 records were filed at CNIPA, versus 42 in the US and 21 at the EPO — the centre of gravity for this claim space sits firmly in China. Filings climbed from 2 in 2017 to a peak of 127 in 2024. With 2022 sitting at 56 — roughly the midpoint of that climb — the trajectory reads as a fast run-up followed by a plateau rather than sustained acceleration. The 2025-2026 figures are still incomplete: publication typically lags filing by about 18 months, so recent years will revise upward as more applications publish.

Common questions about VPP demand response patents
Who holds the most patents on virtual power plant demand response?
Filing activity is concentrated among Chinese state grid utilities and their affiliated power-science research institutes, which together account for the largest share of the 521 families in this dataset. These entities frequently co-file with each other, forming a small number of strong co-assignee pairs rather than broad multi-party consortia. International corporates such as LG Energy Solution appear later in the timeline with narrower, more specific device and method claims rather than broad architecture claims.
Why are most virtual power plant patents filed in China?
412 of the 521 records in this dataset were filed at CNIPA, far ahead of the US (42) and the EPO (21). This reflects both the scale of China’s grid-modernisation programme and the presence of large state grid utilities that file defensively and prolifically. Anyone assessing freedom-to-operate for a VPP demand-response product should treat a Chinese prior-art search as a baseline requirement, not an optional extra, regardless of the target launch market.
Is the virtual power plant patent space still growing?
Filing volume grew from 2 records in 2017 to a peak of 127 in 2024, but the midpoint year of 2022 (56 filings) shows growth flattening well before that peak rather than accelerating into it. Several of the most active named assignees show zero filings in the most recent tracked year, a -100% year-on-year drop. That pattern is more consistent with an early wave of filers having already staked out the obvious claim territory than with a technology in early growth.
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.
Method: Filing trend and technology composition. Derived from a Patsnap search on Virtual Power Plant Demand Response covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
