Flow Map

Each patent family counts as one connection per partner firm per year. A family linked to two partner firms in the same year counts as two connections.

These relationship metrics cover observed cross-border filings with identifiable representatives on both sides in the served sources. IP5 support does not mean every filing or representative is captured.

US representative evidence is limited to granted documents in the source; pre-grant filings without that evidence are absent from counsel relationships. This is a counsel-evidence limit, not a cutoff for corridor filing volume.

No observed relationship is not proof that the firms have never worked together. Missing representative evidence and unlinked identities can leave gaps.
