1,845 utility models and 3,641 inventions. Structural and tooling improvements are often protected faster as utility models.

Method: Utility model documents ÷ all documents

INSIGHT 03Fact

27%

27% carry a green-technology tag

1,070 documents carry the CPC Y02 (climate change mitigation) tag.

Method: Documents with Y02 ÷ documents with CPC

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 2024-01-01 to 2024-12-31. Examination and publication processes affect this timing; it does not directly measure R&D investment in the same period.

Cells count publications only within the collected names and dates. Missing periods are not shown; the company portfolio is incomplete.

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.

Invention applications are generally published about 18 months after filing, or priority where claimed, and may be published earlier. Flags are estimated as of 2026-10-19. 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.
