200 applications in this field, 115 of them in IPC H01M (Batteries, electrochemical cells) — the main axis of the portfolio.
Method: Field applications ÷ applications with IPC
595 applications with IPC codes are mapped to 35 fields using the WIPO IPC–Technology Concordance; area is the number of applications. Select a tile to see its IPC subclasses. An application can belong to several fields.
Publications per month in each field; brighter cells mean more. It shows which directions surge in particular months.
This chart covers collected documents published from 2025-01-01 to 2025-12-31. Examination and publication processes affect this timing; it does not directly measure R&D investment in the same period.

Documents in the current publication window are deduplicated by application number and grouped by filing year. These are not the company's complete annual filings; older applications may only be published or granted within this window.
Invention applications are generally published about 18 months after filing, or priority where claimed, and may be published earlier. Flags are estimated as of 2026-10-29. An unflagged year is still not necessarily complete; these counts cannot establish growth or contraction in R&D.
Multi-year evolution · With a longer collection window, this becomes a yearly view that marks the fastest-growing and shrinking fields.
Four reproducible structural ratios, with the other published companies on the same scale. Entity scopes and windows can differ, so read relative positions only — this is not a ranking.
Position 18 of 20 published companies.
Method: Sum of squared field shares
Position 9 of 20 published companies.
Method: Utility model documents ÷ all documents
The source has no CPC codes, so this cannot be computed.
Method: Documents with CPC Y02 ÷ documents with CPC
Position 4 of 20 published companies.
Method: Applications in measurement, chemical engineering, handling and machine tools ÷ all applications
Organisations that filed jointly with the collected entities; line weight represents joint applications. Name-based candidates and reviewed relationships are labeled separately. Co-applications alone do not prove ownership.
Possible affiliation is a review lead only. Co-applicants without a review record are not automatically group members or external partners, and their independent filings are not added to these statistics.
Review the entity listEntity review and data coverage are separate facts. This list shows the current entity configuration, evidence and relationship dates, matched name by name against this snapshot.
Filters change only the entity list below, not the statistics. A complete group snapshot is not available to switch to on this page.

Review evidenceRelationship dates help interpret renaming, acquisitions and joint ventures. Missing dates do not establish an indefinite relationship or verify the current patent owner.
Written by editors after reading the patent texts and company materials. Verified facts and inferences are labeled, each with evidence and limits.
Select a theme to filter reviewed patents and observations that cite them. Counts are editorial samples only; one patent may belong to several themes. They do not describe the full portfolio distribution.
Themes describe the technical directions in these samples. Links to adoption in specific products, commercialization or commercial value have not been established.

Verified fact
The electrode snippet identifies feed equipment, calendering rolls and a controller; the connector snippet identifies sockets and concentric sleeves. These structures do not establish manufacturing cost or charging performance.
Evidence

Verified fact
The model snippet describes vehicle-sensor image acquisition at a threshold frequency and models operating at different frequencies. Full coordination and control relationships remain unreviewed.

Hand-picked documents that illustrate technology themes — not a ranking of core patents and not representative of the whole.
US20250253307A1
The snippet describes dry-electrode manufacturing with a material-delivery system, two calendering rolls and a controller. The full control relationship has not been reviewed.
US12469999B2
The title identifies a liquid-cooled charging connector. The snippet describes two electrical sockets and concentrically coupled sleeves, but does not show the complete coolant path.
US20250335796A1
The snippet describes machine-learning models operating at different frequencies and acquiring images from vehicle-mounted sensors at a threshold frequency. Subsequent object-location processing is truncated.

Publications are deduplicated by publication number; applications by application number, so a publication and its grant count once; families by the source family ID. Technology fields are derived automatically from IPC codes using the WIPO IPC–Technology Concordance (March 2026), without manual or AI labeling.
Publication or grant documents do not establish current rights. Check legal status and current owners with the relevant patent office.
These statistics use only the applicant names and publication dates collected for this snapshot. They do not represent the full company or group portfolio.
