Same window · published 2025-01-01 — 2025-12-31Some 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.

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.
