Sector Coupling & Multi Energy System Patents: Leaders 2026
Sector Coupling and Multi Energy System Patents: Who Files, and Where the Claim Space Sits
Filing peaked in 2017 at 7 records and the 2021-to-2024 span shows a full -100% drop, though 2024 onward is the last window publication lag lets us treat as complete. Filings peaked at 7 in 2017. The 2021-to-2024 window shows a documented -100% swing (4 down to 0), but treat 2025 and 2026 as still filling in rather than as evidence of a stalled field, since publication lag has not caught up with those filing years yet.

Common questions about this landscape
How many companies actively hold patents in sector coupling and multi-energy systems?
The assignee ranking for this dataset returns 11 companies, headed by a leader with 11 records and dropping to a single record at tenth place. This is the complete ranking the search returns, not a top-50 or top-100 cut, so it should be read as a genuinely small field rather than a filtered view of a larger one. That said, the ranking is counted in patent families, so applicants with only design or continuation filings outside the family structure would not add separate entries.
Is patent filing in this space growing or shrinking?
Filing peaked at 7 records in 2017 and the documented complete-year span shows a drop from 4 filings in 2021 to 0 in 2024, a -100% change. However, publication lags filing by roughly eighteen months, so 2025 and 2026 filings are still being published and should not yet be read as confirming continued decline. Anyone using this trend for a go/no-go filing decision should revisit it once the 2025 filing year is complete.
What technology areas dominate the patent claims in this dataset?
Among the power-systems classes, H02J (power supply and grid systems) and H02M (power conversion) each cover 12.2% of the 41 records, with G05B (control and regulating systems) at 9.8%. A number of records also carry diagnostic and radiation-measurement classes, which reflects the breadth of the underlying keyword search rather than a technical finding about sector coupling itself. Because a single record can carry multiple IPC classes, these percentages sum to more than 100% and should not be read as slices of one pie.
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 Sector Coupling and Multi Energy Systems 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.
