Li-Ion Operando Characterization Patent Snapshot 2026
Li-ion operando characterization remains an early-stage but rapidly accelerating field, with CPS Technology Holdings LLC holding the largest single share and India emerging as the dominant filing jurisdiction. Activity has grown 167% in the recent window, with the corpus still in a growth phase supported by a mix of industrial and academic applicants.
CPS Technology Holdings leads a fragmented, India-centric field
CPS Technology Holdings LLC ranks first with 5 patent records, followed by Vellore Institute of Technology with 4 and Zhejiang Hangke Technology with 3. The top five filers together account for 37% of the combined total among the ranked applicants visible in this query, signaling a moderately concentrated leading tier atop a broadly distributed field.
The tier gap between the top two applicants is narrow — one record separates first from second — and the remaining ranked applicants each hold only one or two records. This flat distribution below the top three suggests no single player has yet established a commanding defensive position.

The presence of multiple Indian academic institutions (Vellore Institute of Technology, K S Rangasamy College of Technology, National Institute of Technology Karnataka, and St Joseph’s College of Engineering) alongside industrial players indicates that foundational research is still being converted into IP rather than concentrated in a single commercialization-focused entity.
Filing counts for the most recent 18–24 months are likely understated due to standard patent publication lag; apparent activity in 2025 and 2026 should be read as a lower bound. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity accelerating since 2022; battery-core IPC classes dominate
The annual filing trend and technology composition together reveal a field moving from isolated early filings into a sustained growth phase, concentrated in battery-cell and measurement classification branches.
Annual filing trend
Filings were negligible through 2021, with a single record in 2022 and 2023 each, before accelerating to 6 records in 2024 and 7 in 2025. The 2026 figure of 4 is almost certainly understated by publication lag and should not be read as a slowdown. The 167% growth in the recent window confirms the field is in a genuine growth phase.

H01M (Batteries, cells and fuel cells) is by far the visible IPC branch with 28 records, reflecting that operando work is anchored in cell-level characterization. G01R (Electric and magnetic measurement) contributes 12 records, and H02J (Power supply and grid systems) adds 10, indicating a secondary cluster around in-situ electrical diagnostics and pack-level monitoring. Lower-count branches — B60K, G06F, C25B, G01B, G01N — represent adjacent but under-served technical directions.

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.
CPS Technology Holdings LLC
CPS Technology Holdings LLC leads with 5 patent records, concentrated entirely in H01M (Batteries, cells and fuel cells) sub-classes covering battery architecture and cell integration. The applicant momentum data does not list CPS among new entrants, suggesting its position pre-dates the recent surge and is more established than most peers in this corpus. Its US-anchored filing strategy contrasts with the India-centric rest of the field.
5 patent recordsVellore Institute of Technology
Vellore Institute of Technology holds 4 patent records, with technology emphasis spanning H01M 10 (battery cells), G01R 31 (electrical measurement), and B60L 58 (electric vehicle propulsion), reflecting an applied diagnostic orientation. Its presence as an academic institution in second place underscores how much of the current IP generation in this field originates from research rather than commercial development. Momentum data does not flag it as a new entrant, indicating sustained rather than sudden activity.
4 patent recordsFrequently asked questions
The corpus covers 22 patent families in scope. This is a small but growing body of IP, reflecting a field that only began accumulating meaningful filings from 2019 onward.
CPS Technology Holdings LLC leads with 5 patent records, followed by Vellore Institute of Technology with 4 and Zhejiang Hangke Technology with 3.
India is the leading jurisdiction with 16 patent records, driven by a large share of academic and industrial Indian filers. The United States follows with 7 records, and Europe (EPO) has 3.
The field is in a growth phase. Recent-window growth stands at 167%, and annual filings have risen from near zero before 2022 to 6 records in 2024 and 7 in 2025. The 2025 and 2026 figures are likely understated due to publication lag and should be treated as lower bounds.
H01M (Batteries, cells and fuel cells) is visible with 28 classified records. G01R (Electric and magnetic measurement) contributes 12 records and H02J (Power supply and grid systems) adds 10, forming the core technical cluster. Branches such as G01N, G06F, and C25B each have 2–3 records and represent adjacent but under-served areas.
Only one co-applicant relationship appears in the evidence: Johnson Controls Technology Co. filing jointly with Johnson Controls New Energy Battery Research & Development (Shanghai), reflecting intra-corporate coordination. No cross-institutional or industry-academic co-filing pairs are recorded, indicating the collaboration ecosystem is still nascent.
