Solid-State Battery Simulation Patent Landscape 2026
The solid-state battery simulation field is in a confirmed growth stage, with 109 patent families on record and a 26% recent-window expansion, led by GS Yuasa Corporation and Samsung Electronics. Filing activity is concentrated in the United States, and the top five filers command nearly half the output of the hundred largest filers, signaling a moderately oligopolistic field that remains open to targeted entrants.
GS Yuasa and Samsung lead a moderately concentrated growth-stage field
GS Yuasa Corporation holds the top position with 19 patent families, followed by Samsung Electronics with 15 and the University of Colorado Regents with 12. The top five filers collectively account for 48% of the combined output of the hundred largest filers, indicating meaningful but not overwhelming concentration.
A clear two-tier structure is visible: GS Yuasa and Samsung sit well ahead of the third-ranked academic entrant (University of Colorado, 12 patent families), which in turn leads Corning (9) and Toyota (7). The gap between tier one and the rest is notable but not prohibitive for a challenger with focused technical differentiation.

The leaders’ positions imply that both device manufacturers and chemical/materials companies have staked early claims, while universities occupy the third slot — a pattern consistent with a field where fundamental simulation methodology is still being established alongside applied engineering work.
Figures for 2024–2026 are subject to publication lag and likely understate true filing activity for those years; the apparent trend should be read as a floor, not a ceiling. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Annual filings rising with strong battery-cell dominance; adjacent branches remain thin
The filing trend and technology composition charts together reveal a field accelerating from a small base, with H01M (batteries, cells and fuel cells) accounting for the entire 109-family corpus while adjacent classes such as G06F (digital data processing) and C04B (ceramics) represent a fraction of that volume.
Annual filing trend
Annual filings grew from 6 families in 2017 to a recorded peak of 23 in 2024, with 22 in 2025; the 2025–2026 bars are undercounted due to publication lag and should be treated as minimums. The overall multi-year trajectory confirms the Growth lifecycle stage, with a 26% recent-window increase.

H01M (batteries, cells and fuel cells) is the primary class covering all 109 families. Secondary branches — H01B (conductors/insulators, 25 records), C01B (inorganic compounds, 22), G06F (digital data processing, 14), and C04B (ceramics, 9) — are present but individually sparse, reflecting that computational and materials-science simulation sub-disciplines are still underrepresented relative to the electrochemistry core.

What the patent structure means for R&D investment decisions
Three structural signals — a growth lifecycle, a two-tier competitive gap, an active cross-sector collaboration cluster, and US-dominant geography — together define where R&D investment is most and least contested.
Growth stage with annual filings still rising
The lifecycle evidence confirms a Growth stage: annual filings are still rising and the 26% recent-window increase has not yet eased from any prior peak. This means foundational simulation methodologies are still being filed and claim scope tends to be broader, making early positioning in emerging sub-branches particularly valuable. Teams entering now can still capture broad coverage rather than being forced into design-arounds.
Growth stageTop five hold 48% of leading-filer output — room for challengers
The top five filers account for 48% of the combined output of the hundred largest filers, placing the field in a moderately concentrated zone. The tier-two group (Corning, Toyota, FDK, GS Yuasa International, Samsung SDI) clusters between 5 and 9 patent families each, creating a realistic path for a focused challenger to enter tier two within a standard R&D cycle. The weakest signal for incumbents is that all top-seven applicants carry a ‘new entrant’ momentum tag, indicating the field has not yet produced entrenched long-term holders.
Moderate concentrationSamsung Electronics and UC system are the most active co-filers
The most active co-filing relationship is between Samsung Electronics and the University of California Board of Regents (5 joint patent families), with a secondary link between Samsung Electronics and another UC entity (1 family) and a UC–UC connection (1 family). This industry–academia cluster is currently the only documented collaboration network in the corpus, suggesting that cross-sector partnerships are nascent. An entrant that can replicate or extend this model — pairing industrial simulation expertise with university materials science — is positioned to move quickly.
Industry–academia clusterUnited States is the primary protection market; Japan and China follow
The United States leads jurisdictions with 54 patent records, more than double Japan (22) and China (17), with Europe (EPO) also at 17. WIPO PCT filings number 5, suggesting that most applicants are filing nationally rather than pursuing broad international routes. For an entrant, this pattern implies that US filing is essentially mandatory, while Europe and Japan are secondary but contested markets; China at 17 records is relatively open given the scale of Chinese battery manufacturing activity.

Co-filing pairs, ranked by the number of jointly-filed patent families.
GS Yuasa and Samsung Electronics lead with distinct technical emphases
The two front-runners differ in their secondary technology focus: GS Yuasa extends heavily into conductor/insulator materials (H01B), while Samsung Electronics pairs its battery-cell work with electrode materials (H01M4) and inorganic compounds (C01B). Both carry a ‘new entrant’ momentum tag, consistent with the field’s recent acceleration.
GS Yuasa Corporation
GS Yuasa Corporation holds 19 patent families — the largest single-applicant position in the corpus. Its technology emphasis spans battery-cell simulation (H01M10, 19 records), conductor/insulator materials (H01B1, 18 records), and inorganic phosphate compounds (C01B25, 9 records), indicating a vertically integrated simulation approach covering electrolyte chemistry and ionic transport. Momentum is classified as a new entrant, reflecting that its filings are concentrated in the recent window (9 families in the most recent period).
families: 19Samsung Electronics Co., Ltd.
Samsung Electronics holds 15 patent families, placing it a close second. Its focus sits on battery-cell simulation (H01M10, 15 records) and electrode simulation (H01M4, 13 records), supplemented by nitrogen-compound chemistry (C01B21, 4 records). Notably, Samsung is also the anchor of the field’s only documented collaboration network, co-filing 5 families with the University of California Board of Regents. Momentum is similarly classified as a new entrant, with 7 families in the recent period.

Under-served adjacent branches worth monitoring
Several IPC classes appear alongside the dominant H01M core but at low counts, representing areas where simulation methodology intersects adjacent technical domains that are sparsely patented relative to their potential relevance to solid-state battery development.
G06F · Electric digital data processing
With 14 patent records, G06F is the largest adjacent branch by count yet covers only about 6% of the corpus by share — sparse relative to the central role that numerical solvers, finite-element models, and digital twins play in battery simulation workflows. The low count may reflect that pure software simulation methods are being filed under H01M rather than G06F, or that computational methods remain under-protected. An entrant with expertise in physics-based digital twin platforms or machine-learning surrogate models for electrochemical systems could file targeted G06F claims with limited direct competition. Entry path: focus on novel solver architectures or reduced-order models tied to solid-state electrolyte interfaces.
Search this in Eureka →C04B · Ceramics, cement & refractories
C04B appears in 9 patent records (4% share), primarily through Corning’s ceramic shaping work (B28B1 linked, C04B35). Ceramic electrolyte simulation — covering sintering behavior, grain-boundary ionic conductivity modeling, and thermal stress prediction — is a technically critical sub-domain for oxide-based solid electrolytes (e.g., LLZO, LATP). The sparse coverage in C04B suggests that simulation of ceramic processing parameters is not yet systematically protected. An entrant with ceramics process simulation capability — particularly linking sintering kinetics to ionic transport models — could find limited prior art and broad claim potential in this branch.
