Patent source coverage
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.

Scope & definitions
Partner observations count families within each representative pair and filing year, then sum the selected years. Co-counsel can create several pairs for one family, so adding pair counts can exceed the distinct corridor or firm family count.
