Patent Landscape · Solid-State BatteriesSolid-state battery patents: mapping filers, claim density and the gaps still open
- Concentrated but not locked up. the ranked leader holds 131 records and the top five together account for 17.6% of all 2,540 records in scope — well short of a closed field.
- Filing has cooled from its 2022 peak. 353 records that year, with the 2021-to-2024 span showing a -51% change now that 2024 is the last complete filing year.
- Claim activity leans hard on cell chemistry. H01M covers 71.5% of all records, while power-conversion and measurement subclasses each sit under 6%.

Leading Jurisdiction
Filing growth compares 2021 (295 records) with 2024 (145) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 2,540 records in scope (CR5), not by the ranked leaders only.

Field Overview
What the solid-state battery patent record actually shows
The dataset covers 2,540 published records filed between 2015 and the 2026 cut-off, built around claims that combine solid-state or solid-electrolyte cell architecture with charge-state, electrode-capacity or electrolyte-stability control. That pairing matters: it filters out generic battery filings and keeps records where the solid electrolyte itself is doing claimed work, not just sitting in a background paragraph. Publication lags filing by roughly 18 months, so the last one to two years in any trend chart will always look thinner than the underlying filing activity actually was.
Filing volume rose through the late 2010s, peaked in 2022 at 353 records, and has since declined through the last complete year of data. The assignee ranking spans 100 companies, with the leader well ahead of the field but the combined share of the top ten still under 30% of all records — evidence of an active, multi-player field rather than a settled duopoly.

The Numbers
Filing trend and technology composition
Two views of the same 2,540 records: how filing activity has moved year over year, and which IPC subclasses the claims actually sit in.
A 2022 peak, then a cooling filing curve
Annual filings climbed from 136 in 2017 to a peak of 353 in 2022, then declined to 145 by 2024 — a -51% change over that 2021-to-2024 span, the last window where the data can be treated as complete. Readings from 2025 onward are still filling in as publications catch up with filing dates, so they should not be read as confirmation the field is shrinking.
H01M dominates; adjacent subclasses stay thin
H01M (batteries, cells & fuel cells) appears in 71.5% of all 2,540 records, confirming most claims are anchored in cell and electrolyte structure itself. H02J (power supply & grid systems) and B60L (EV propulsion) follow at 18.4% and 14.8%, while measurement (G01R), insulation (H01B), inorganic chemistry (C01B), electrotherapy (A61N) and power conversion (H02M) each sit at 5.6% or below — each class can appear alongside others on the same record, so shares add to more than 100%.
Shares are the percentage of the 2,540 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

What the trend and composition data mean for a filing decision
Four patterns stand out once volume, timing and classification are read together.
Filing Trend
-51%
2021 to 2024 change
A post-peak field, not a dying one
Filing peaked at 353 records in 2022 and has fallen through 2024, the last complete year available. That decline could reflect consolidation around fewer, larger filers rather than shrinking interest — the ranked leader board still shows 100 active assignees.
Treat 2025-2026 figures as provisional given publication lag.
Concentration
17.6%
top 5 share of 2,540 records
A leader, then a long tail
The top-ranked assignee holds 131 records against a fifth-place figure of 68 and a tenth-place figure of 41 — a steep early drop-off followed by a long tail across the other 90 ranked companies.
Top 10 combined reach 27.8% of all records in scope.
Technology Mix
71.5%
records tagged H01M
Claims cluster on cell architecture
Nearly three-quarters of records touch H01M, confirming that most inventive activity is still about the cell and electrolyte itself rather than surrounding power electronics or measurement systems.
H02J and B60L trail at 18.4% and 14.8% respectively.
Geography
1,132
US-filed records
US and EPO dominate the filing venues
The United States leads receiving offices with 1,132 records, ahead of EPO at 455 and WIPO/PCT at 339; Japan, Germany and India each sit in the 80s, suggesting protection strategy still centres on US and European coverage before broader PCT expansion.
Figures count receiving office, not applicant nationality.

Competitive Landscape
Who is filing, and where the field is still open
The ranking covers 100 companies returned by the data endpoint — not a top-50 or top-100 cut, the full set the ranking includes. Momentum in the latest year should be read cautiously given publication lag.
Leader Position
131
records, ranked leader
A clear leader without a monopoly
The top-ranked assignee's 131 records give it a visible lead, but the top 5 combined still represent only 17.6% of all 2,540 records — most of the field's claim space remains distributed across the other ranked companies.
Fifth place holds 68 records; tenth place holds 41.
Latest-Year Momentum
0
latest-year filings, several leaders
Several top filers show zero in the latest year
Multiple leading assignees show 0 records and a -100% year-on-year change in the most recent year tracked. Given the roughly 18-month publication lag, this most likely reflects filings still working through the pipeline rather than an actual halt.
Read latest-year momentum figures as provisional, not final.
Collaboration
10
co-assignee pairs identified
Co-filing is rare and concentrated
Only 10 co-assignee pairs appear across the dataset, with the strongest pairing linking two automotive-sector filers on 7 shared records. Most organisations in this field file independently rather than through joint ventures.
The next-strongest pairs each appear on 5 shared records.

Next Steps
Where to take this analysis next
The dataset points to specific follow-up work depending on whether the goal is freedom-to-operate, portfolio strategy, or scouting.
Run a freedom-to-operate check on H01M sub-claims
Given that 71.5% of records sit in H01M, a targeted claim-chart review of that subclass against a specific electrolyte or electrode design will surface conflicts faster than a broad landscape read.
Explore claim charts in Eureka →Track the ranked leaders' latest filings directly
Several top assignees show a sharp drop in latest-year counts that publication lag alone may not fully explain; monitoring their newest applications as they publish will clarify whether this is a pause or a real pivot.
Set up assignee monitoring in Eureka →Test claim language in the under-claimed branches
The thinner subclasses — power conversion, measurement, insulation — carry far fewer records than H01M and may offer more room for a defensible first claim.

FAQ
Common questions on solid-state battery patents
Within this dataset of 2,540 records, one assignee leads the ranked list with 131 records, noticeably ahead of the fifth-place company at 68 and tenth place at 41. That said, the top 5 combined only reach 17.6% of all records in scope, so no single company controls the field; the remaining records are spread across a ranked list of 100 companies. Anyone assessing competitive position should look at the full ranking rather than the leader alone, since a long tail of single- and few-filing entrants makes up most of the volume.
Filing peaked at 353 records in 2022 and had fallen to 145 by 2024, a -51% change over that three-year span — the last period the data treats as complete. Because publication typically lags actual filing by around 18 months, figures for 2025 and 2026 are still filling in and should not yet be read as confirmation of a continued decline. The honest read is that the field has cooled from its 2022 high, not that it has stopped.
The dominant classification is H01M (batteries, cells & fuel cells), present in 71.5% of all 2,540 records, confirming most claims focus on cell and electrolyte structure itself. Power supply and grid systems (H02J) and electric vehicle propulsion (B60L) follow at 18.4% and 14.8% respectively, with measurement, insulation, inorganic chemistry, electrotherapy and power conversion each under 6%. Because a single record can carry several IPC codes, these percentages overlap rather than sum to 100%.
The United States receives the largest share of filings in this dataset at 1,132 records, followed by the European Patent Office at 455 and the WIPO/PCT route at 339. Japan, Germany and India each sit in the 80s, well behind the leading venues. This pattern suggests most applicants prioritise US and European protection first, using PCT filings to keep broader international options open rather than filing nationally everywhere at once.
Relative to the dense H01M cluster covering 71.5% of records, subclasses like power conversion (H02M, 2.4%), measurement (G01R, 5.6%) and insulation/conductor materials (H01B, 4.0%) are thinly claimed. That gap suggests under-explored territory in areas like solid-electrolyte power-conversion integration or in-situ electrolyte stability sensing, where a well-drafted first claim may face less crowded prior art than a straight electrolyte-composition claim would.
