Utility models are 2.2%
3 utility models and 135 inventions. Structural and tooling improvements are often protected faster as utility models.
Method: Utility model documents ÷ all documents
02Technology landscape
138 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.
- Electrical engineering

03Rhythm
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.

Filing years of the collected applications
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.
- 20234
- 2024132
- 20252Publication lag may still apply
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.

09Method and sources
Counting units
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.
