Inverter Based Resource Modelling Patents: Who Leads 2026
Inverter Based Resource Modelling Patents: Mapping Who Files and What Remains Open
Filing is concentrated in China. 11 of 12 receiving-office filings are Chinese, with a single Canadian filing from Quanta Technology representing the non-Chinese route into this space. Activity in scope was flat at zero for most of the tracked period, then reached a peak of 6 filings in 2025. With fewer than four complete years of meaningful activity once publication lag is accounted for, no growth rate can be reliably stated — but the shape shows a technology area that only recently became patent-active.

Common questions on inverter based resource modelling patents
What is an inverter based resource model in a patent context?
In this dataset, it refers to a mathematical or software representation of a grid-connected inverter, converter or plant, built for use in electromagnetic transient simulation or interconnection studies. Patents in this space typically claim a method for identifying the model’s parameters, a way of validating that the model’s transient response matches the physical device, or a technique for exporting a trained model between simulation platforms. The representative filing in this landscape, CA3230547A1, covers exactly this last case: exporting a black-box model trained with machine learning from one software platform to another.
Who are the leading patent filers in inverter based resource modelling?
The ranking includes 17 assignees, led by an organisation with 2 records, with fifth and tenth place each holding 1. That is a flat distribution rather than a concentrated one, so no single filer currently controls a broad claim position. Most of the ranked organisations are Chinese grid operators or their affiliated research institutes, reflecting the fact that 11 of the 12 filings in scope came through China’s receiving office.
Is this patent space dominated by Chinese filers?
Yes, on receiving-office data: 11 of the 12 filings in scope were routed through China, against a single Canadian filing. That single non-Chinese filing, from Quanta Technology, is also the dataset’s most detailed black-box modelling claim, which makes it worth tracking closely even though it is a minority of the filings by volume. This pattern may simply reflect where this specific query surfaces activity rather than the full global picture of inverter modelling research.
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 Inverter Based Resource Modelling 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.
