Li-Ion Cell & Electrode Design Optimization Patent Snapshot
The corpus retrieved for Li-Ion cell and electrode design optimization is extremely small — only 2 patent families, all filed in India — indicating that the query as scoped captures a nascent or highly specific slice of the broader li-ion design space. Activity is not concentrated around a single dominant organization; instead, filings are spread across numerous individual inventors at parity, with no corporate or institutional leader emerging.
No dominant leader — individual inventors hold all filings at parity
Every applicant in the ranking holds exactly 1 patent record, with DR G BALARAMAN appearing first by alphabetical tie-break rather than volume advantage. The top five filers account for 36% of the ranked applicants visible in this query’ combined total, but because the corpus is so small, this concentration figure should be read with caution.
There is no meaningful tier gap between a leader and challengers — all 14 ranked applicants are at identical filing volume. This flat structure is characteristic of very early-stage or narrowly scoped patent activity where individual inventors are visible in and corporate programs have not yet entered.

The absence of any corporate or institutional applicant suggests that this specific combination of li-ion cell and electrode design optimization has not yet attracted organized R&D investment in India, at least within the scope retrieved. This may represent a genuine early-mover window or a scoping artifact requiring a broader query to validate.
The most recent filings are subject to publication lag of 18–24 months; any absence of activity in 2025 should not be treated as a real pause. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sparse, episodic filing pattern across H01M and G01R branches
The annual filing trend and technology composition charts together reveal a field with minimal cumulative activity and a narrow IPC footprint centered on battery cell chemistry and electrical measurement.
Annual filing trend
Filings recorded zero activity from 2017 through 2023, with one filing in 2024 and one in 2026. This episodic pattern reflects either a very nascent local research effort or a narrow query scope rather than an established innovation program. The 2025–2026 period is subject to publication lag and should not be read as a settled trend.

H01M (Batteries, cells and fuel cells) is visible in with 2 patent records, confirming that cell-level design is the core focus. G01R (Electric and magnetic measurement) appears with 1 patent record, indicating that measurement and characterization methods — likely battery state estimation or electrochemical diagnostics — are an adjacent technical concern for several applicants.

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.
DR G BALARAMAN
DR G BALARAMAN holds 1 patent record and appears first in the ranking. Their technology focus spans G01R 31 (electric and magnetic measurement) and H01M 10 (batteries, cells and fuel cells), suggesting an interest in cell characterization alongside core battery design. Momentum data does not flag a recent-window new-entrant signal for this applicant.
patent records: 1DR SUBHALAXMI PRADHAN
DR SUBHALAXMI PRADHAN holds 1 patent record and is flagged as a new entrant in the most recent filing window. Their focus is concentrated in H01M 10 and H01M 4 — core cell and electrode chemistry branches — making them one of four new entrants (alongside DR SHIWANI SINGHA, DR MONIKA CHAUHAN, and DR LALIT PRASAD) whose recent activity signals nascent individual-level engagement with electrode design.
patent records: 1Frequently asked questions
The corpus contains 2 patent families. This is a very small dataset and conclusions drawn from it should be validated against a broader search before informing follow-up research decisions.
India is the sole jurisdiction represented, with both patent records filed there. No US, European, Chinese, or PCT filings appear in this scoped dataset.
DR G BALARAMAN appears first in the ranking with 1 patent record, followed by 13 other individual inventors each also holding 1 patent record. No corporate or institutional applicant is present.
H01M (Batteries, cells and fuel cells) is the primary branch with 2 patent records. G01R (Electric and magnetic measurement) is a secondary branch with 1 patent record, reflecting interest in cell diagnostics alongside design.
No co-applicant pairs were detected in this corpus. All filings appear to be individual inventor submissions with no evidence of collaborative or institutional partnerships.
The trend shows zero activity from 2017 through 2023, one filing in 2024, and one in 2026. This episodic pattern does not establish a growth trajectory; it reflects nascent or narrowly scoped activity. The 2025–2026 window is subject to publication lag and should not be read as a settled trend.

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.
