Li-Ion Electrode & Assembly Automation Patent Snapshot
The retrieved corpus for this precise query is extremely narrow, returning a single patent family filed in 2021 and assigned jointly to two French public-research institutions. At this query granularity, the corpus is too small to draw reliable competitive-structure conclusions; broadening the search scope is recommended before making R&D investment decisions.
A single-family corpus dominated by French public research
The top-ranked applicant in this corpus is CNRS (Centre National de la Recherche Scientifique), holding the only patent record retrieved, alongside Institut National de la Recherche Scientifique — both French public research bodies.
Concentration is absolute: the top five filers account for 100% of the ranked applicants visible in this query’ combined total, reflecting the corpus’s minimal size rather than any genuine market dynamic.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | Centre National de la Recherche Scientifique (CNRS) | 1 | |
| 2 | Institut National de la Recherche Scientifique | 1 |
The leaders’ positions indicate academic rather than industrial ownership at this query scope, suggesting that commercially focused electrode-assembly automation filings may be captured under different IPC subclasses or search terms.
The most recent period reflects publication lag and a corpus that is too small to support trend interpretation; results should be validated with a broader query before drawing strategic conclusions. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2021 filing event with no surrounding activity
The annual filing trend and technology composition charts both reflect a one-record corpus; patterns visible here should be treated as query artifacts rather than field-level signals.
Annual filing trend
All activity resolves to a single record in 2021; all other years in the window return zero. This is consistent with a very narrow query rather than a genuine field-level pause. Recent years are additionally subject to publication lag.

The entire corpus falls within H01M (Batteries, cells & fuel cells), specifically subclasses H01M 10 and H01M 4. No other IPC branches appear, indicating that adjacent automation-related classes (e.g. B65G, B23P) are not captured by the current query.

The present invention relates to a novel gold-based porous material, the use of said gold-based porous material as a precursor of a negative active material, the preparation process of said gold-based porous material, a novel gold-based porous material comprising lithium, the use of said gold-based porous material comprising lithium as a negative electrode… (excerpt from the patent abstract)


Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. 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.
Centre National de la Recherche Scientifique
CNRS holds 1 patent record in this corpus, focused on H01M 10 (secondary batteries) and H01M 4 (electrodes). As a public research body, its filing posture reflects academic IP protection rather than commercial product deployment. No momentum trend data is available given the single-record corpus.
families: 1Institut National de la Recherche Scientifique
INRS co-files the same single record with CNRS, sharing identical technology focus in H01M 10 and H01M 4. The two institutions appear to be collaborating on the same research output rather than competing. No separate momentum trajectory can be established from this corpus.
families: 1Frequently asked questions
The retrieved corpus for this specific query returns a single patent family. This is most likely a query-scope effect — electrode and assembly automation patents may be filed under different terminology or IPC classes not captured here. Broadening the search terms and including mechanical/process-control classes is recommended.
Centre National de la Recherche Scientifique (CNRS) and Institut National de la Recherche Scientifique (INRS), both French public research institutions, are the only filers, each holding one patent record as co-applicants on the same filing.
The single retrieved record falls entirely within H01M (Batteries, cells & fuel cells), specifically subclasses H01M 10 (secondary batteries) and H01M 4 (electrodes). Automation-oriented classes such as B23P or G05B are not represented.
The one patent record in the corpus was filed at the United States patent office. No EP, CN, JP, or KR counterparts are captured in this query’s results.
The lifecycle stage is classified as Decline because annual filings have eased back from the 2021 peak, with a recent-window growth of -100%. Given the single-record corpus, this classification reflects the absence of subsequent filings under this query rather than a genuine contraction of the broader technology field.
Teams should run a broader search incorporating related IPC classes (e.g. B23P, B65G, G05B), alternative search terms covering electrode coating, winding, stacking, and cell assembly automation, and verify coverage across major jurisdictions including CN, JP, KR, and EP before drawing investment or freedom-to-operate conclusions.

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. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
