Technology portfolios compared in the same window and counting units. Scale is compared only within the same field or subclass.

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.

Inspect one technology field

Inspect collected applications, portfolio share and supporting publications within one field. A technology overlap does not establish that companies in different industries are direct competitors.

One 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.
