Company overviews, observations and reading samples are verified against Chinese sources and shown in Chinese; statistics, charts and controls are localized.

01Key figures

Applications: 1,770; By application number; publication and grant count once
Invention: 1,005; 57% of applications
Utility model: 765; 43% of applications
Patent families: 1,768; By the source family ID
Green technology: 11.1%; CPC Y02 tag, among documents with CPC
Concentration: 0.27HHI; Sum of squared field shares; higher is more concentrated

INSIGHT 01Fact

42%

42% of applications are in Thermal processes and apparatus

745 applications in this field, 476 of them in IPC F24F (Air conditioning, ventilation) — the main axis of the portfolio.

Method: Field applications ÷ applications with IPC

INSIGHT 02Fact

12%

12% involve manufacturing and inspection

Measurement, machine tools, handling and chemical engineering together reach 209, mostly production-line, equipment and inspection filings.

Method: Four fields added ÷ all applications (fields may overlap)

INSIGHT 03Fact

43%

Utility models are 43%

765 utility models and 1,005 inventions. Structural and tooling improvements are often protected faster as utility models.

Method: Utility model documents ÷ all documents

02Technology landscape

1,770 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
Chemistry
Mechanical engineering
Other fields

03Rhythm

Publications per month in each field; brighter cells mean more. It shows which directions surge in particular months.

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