How to read these metrics
Shares cover only observed cross-border relationships with identifiable firms on both sides, not all foreign filing work. Missing or unlinked representatives are outside this denominator.
Sent share = sent ÷ (sent + received) × 100. Received share = received ÷ (sent + received) × 100. Rounded shares add to 100%; no observations is N/A.
These are filing-based associations, not confirmed instructions or work returned by a partner. Counts and direction can contain gaps or errors.
Smaller / larger direction = smaller flow ÷ larger flow × 100. One-way exchange is 0%; no activity is N/A. It describes observed balance, not who chose the partner.
Family observations count each family once per firm, filing office and year. A family can recur across offices or years; this is not a globally unique patent count. The total counts each family once within a firm, office and year, even if it appears in both directions. Sent plus received can exceed the total. These are not application counts.
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.
