Modular Flow Battery Patent Snapshot 2026
The patent corpus for modular flow battery systems is extremely narrow, with a single family in scope filed by Dalian Rongke Power in China. This signals either a highly nascent or under-indexed niche where IP activity has yet to accumulate at scale.
Dalian Rongke Power holds the sole family in a highly concentrated niche
The ranked applicant list contains one entrant — Dalian Rongke Power — which accounts for the entirety of the top-filer pool in this search scope.
With a single patent family and a single applicant, concentration is absolute. There is no discernible tier gap between a leader and challengers because no challengers appear in the evidence.

Dalian Rongke Power’s position, while unchallenged within this corpus, rests on a very thin filing base; this may reflect the precise specificity of the search query rather than a fully mapped market.
Given the publication lag of approximately 18–24 months, any filings from 2024 onward may not yet be visible in this corpus; the true activity level could be higher than this snapshot suggests. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2018 filing defines the trend; technology is fully concentrated in H01M
The filing trend shows one family recorded in 2018 with no additional activity in subsequent years through 2026. The technology composition is entirely within H01M (Batteries, cells and fuel cells), reflecting the electrochemical storage focus of modular flow battery design.
Annual filing trend
One family was filed in 2018; all other years in the window show zero activity. Given publication lag, filings from 2024–2026 may be under-represented, but the extended gap from 2019 through 2023 is notable even accounting for lag.

The entire corpus sits within H01M (Batteries, cells and fuel cells), with no adjacent IPC classes represented. This reflects the narrow scope of the query and leaves adjacent branches — such as power electronics, thermal management, or system integration classes — unaddressed in the current evidence.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Dalian Rongke Power
Dalian Rongke Power holds 1 patent family in scope, classified under H01M 8 (Batteries, cells and fuel cells), specifically covering a modular flow battery system architecture. Applicant momentum data is not available in the evidence, so trajectory cannot be quantified from this corpus. The company is a known large-scale vanadium flow battery developer in China, which contextualizes this filing within a broader industrial program.
families: 1No challenger identified
No second applicant appears in the ranking for this search scope. Any challenger assessment would require broadening the query to adjacent flow battery or modular energy storage terminology to identify other active filers that may be protecting overlapping technology without using the exact ‘modular flow battery’ framing.
families: N/AFrequently asked questions
The current search scope contains 1 patent family. This is an unusually small corpus and likely reflects the specificity of the ‘modular flow battery’ framing; broadening the query to related terminology would be advisable before drawing market-wide conclusions.
Dalian Rongke Power is the sole applicant in the ranked list, holding 1 patent family in scope. No other applicants appear in the evidence for this specific search query.
The single family in scope was filed in 2018, based on the annual trend data. No filings are recorded in any other year within the 2017–2026 window covered by the evidence.
China is the only jurisdiction represented in the current corpus, with 1 patent record. No PCT, EPO, US, or other national-phase records are present in this search scope.
The single family is classified under H01M (Batteries, cells and fuel cells), specifically H01M 8. No other IPC classes appear in the current corpus.
No co-applicant or collaboration data is present in the evidence for this corpus. This is consistent with a single-family, single-applicant dataset; broader search queries would be needed to assess collaborative activity in the wider flow battery ecosystem.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
