Same window · published 2024-01-01 — 2024-12-31Some name or date coverage is incomplete; affected counts are lower bounds
This is a structural comparison of collected portfolios. The same requested window does not establish equal entity scope, covered months or industry; no competitive ranking is inferred.
Applicant-name coverage differs. The counts below cover only the listed names and do not represent complete company portfolios.

View Midea publications in this fieldOne application may belong to multiple fields, so shares can sum to more than 100%. Drill-down lists publications; an application publication and its grant may appear separately.
02Same problem: shared IPC subclasses
The 10 subclasses in every company's top 60 with the most combined applications. Scale is compared within a subclass, never across different business scopes.

03Where each one leans
Observed emphasis within each company’s collected top-60 IPC subclasses. A dash for another company means outside its top-60 list, not zero applications or a market gap. Incomplete coverage can also change the ordering.

Empty dashed outlines mark uncollected periods. Hatched bars and ≥ counts mark partial coverage.
Publication timing follows examination and publication cycles, not R&D intensity.
What makes it comparableThe same publication window and counting units. Companies with different windows are not put in one comparison.
What is not comparableGroup totals. Business and entity scopes differ; compare scale within a field or subclass.
Not a rankingSimilarity and shares describe structure, not patent value, quality or technical leadership.
