Manganese-Rich Battery Patent Landscape 2026
Manganese-Rich Battery Patent Landscape in 2026
The manganese-rich battery patent corpus is very small — 5 patent families in scope — held by four applicants, with Soulbrain Co. Ltd. holding the largest single share. All meaningful filing activity began in 2023, marking this as an early-stage, nascent technology space.
Four applicants share a highly concentrated, nascent corpus
The manganese-rich battery patent landscape is dominated by a small group of four applicants — Soulbrain Co. Ltd., LG Energy Solution, Contemporary Amperex Technology Co. Ltd. (CATL), and Ford Global Technologies — collectively accounting for all 5 patent families in scope. Soulbrain Co. Ltd. leads with 2 patent families.
Concentration is absolute: the top five filers account for 100% of the combined total across the hundred largest filers. There is no meaningful second tier; each trailing applicant holds a single patent family, reflecting how early-stage and unpopulated this specific sub-field remains.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Soulbrain Co. Ltd. | 2 | |
| 2 | LG Energy Solution Ltd. | 1 | |
| 3 | Contemporary Amperex Technology Co. Ltd. (CATL) | 1 | |
| 4 | Ford Global Technologies LLC | 1 |
The leaders’ positions imply that no single player has yet established an insurmountable portfolio advantage. The low absolute counts mean new entrants face a relatively open competitive landscape, though the presence of large incumbents such as CATL and LG Energy Solution signals that established battery manufacturers are beginning to stake claims.
All filings appear concentrated in 2023–2025; the most recent 18–24 months are subject to publication lag and likely understate current activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity emerged sharply in 2023; core cell chemistry dominates the technology mix
The filing trend and technology composition charts together reveal both the recency and the narrow technical focus of manganese-rich battery IP activity.
Annual filing trend
Zero filings were recorded from 2017 through 2022; 3 families appeared in 2023, followed by 1 each in 2024 and 2025. The apparent step-down from 2023 should not be read as a decline — publication lag means 2024 and 2025 counts are almost certainly incomplete. The field’s activity effectively began in 2023.

All 5 patent families carry the H01M classification (batteries, cells and fuel cells), confirming that the corpus is tightly focused on core electrochemical cell technology. Adjacent branches — C01G (compounds of other metals), G01R (electric and magnetic measurement), and H02J (power supply and grid systems) — each appear once, indicating isolated forays into materials synthesis, battery diagnostics, and charging systems respectively, but no sustained parallel development.

What the nascent structure means for R&D investment
With only 5 patent families filed by 4 applicants since 2023, the manganese-rich battery landscape is pre-competitive in character. R&D teams can shape the IP landscape rather than navigate around a dense existing corpus.
Nascent stage: IP activity began in 2023
The life-cycle stage cannot be formally classified from the available evidence, but the filing timeline is unambiguous — no patent families predate 2023. This places manganese-rich battery IP firmly in an emergence phase. Early movers have a genuine opportunity to define the claim landscape before density increases.
Early-stageAbsolute concentration across four players
The top five filers hold 100% of the combined total across the hundred largest filers. With Soulbrain Co. Ltd. at 2 patent families and three others at 1 each, no applicant has built a defensible blocking position. A focused filing program of even modest scale could shift the competitive balance meaningfully.
High concentrationNo co-applicant activity detected
Evidence pending — no co-filing relationships are present in the corpus. The absence of collaboration may reflect the very small total or the early-stage nature of the field, where technology is still being developed in-house. Partnerships between materials suppliers (such as Soulbrain) and cell manufacturers (CATL, LG Energy Solution) could emerge as the field matures.
No co-filings yetChina and Korea anchor the filing map; US and EPO present
China leads with 2 patent records, followed by Europe (EPO), South Korea, and the United States each with 1. The distribution reflects both the home markets of the applicants and the manufacturing regions most relevant to battery supply chains. Coverage in additional jurisdictions — Japan, for instance — is absent from evidence, which may signal gaps or simply the very early stage of the field.

Soulbrain leads; CATL, LG Energy Solution, and Ford are new entrants
All four applicants entered this specific sub-field as new entrants from 2023 onward. Soulbrain Co. Ltd. holds the largest position; the other three each hold a single patent family with distinct technical emphases.
Soulbrain Co. Ltd.
Soulbrain Co. Ltd. leads with 2 patent families, both classified under H01M 10 (batteries and cells), indicating a focused position in core cell technology rather than peripheral systems. Its momentum is flagged as a new entrant, meaning prior baseline was zero — the entire position was built from 2023 onward.
families: 2Contemporary Amperex Technology Co. Ltd. (CATL)
CATL holds 1 patent family with a broad technical spread across C01G 53 (compounds of other metals), H01M 4 (electrode materials), and H01M 10 (cell technology), suggesting an interest in both materials synthesis and cell-level integration. CATL also entered as a new entrant, consistent with the field’s 2023 origin.

Under-served adjacent branches worth monitoring
The current corpus is almost entirely concentrated in H01M (electrochemical cells). Three adjacent IPC branches each appear only once, representing areas of observed sparsity relative to the dominant class.
G01R · Battery diagnostics and measurement
Only one patent record touches G01R 31 (electrical measurement and testing), filed by LG Energy Solution. Manganese-rich chemistries present unique state-of-health and state-of-charge estimation challenges due to voltage plateau behavior; the sparse presence here suggests that dedicated diagnostic and battery management IP for this chemistry has not yet been developed. Teams with BMS expertise could find an underserved niche, though the small corpus means this observation requires validation against broader BMS patent searches.

A single C01G 53 record — filed by CATL — covers compounds of other metals including manganese-based cathode precursors. Given that manganese-rich cathode material synthesis is a foundational process step, the near-absence of C01G coverage is a notable gap. This branch has direct technical value: precursor composition and synthesis routes determine electrochemical performance and cycle life. The entry path is realistic for materials suppliers or integrated cell manufacturers seeking upstream IP protection.
