Outgoing partner-flow yearly family counts for Korea · Korea → Europe.
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.
No comparable annual pair · 2021–2026 preliminary, not compared.
Compares complete years through 2020 within the selected range. Patent filings publish about 18 months after filing, and foreign filings can enter later, so 2021–2026 are still filling in. This view reads an earlier data snapshot, so its recent years are less complete. Their counts stay in the chart, marked preliminary. No missing filings are estimated or added to the counts.
YoY = (latest complete year − previous year) / previous year × 100, rounded to a whole percent. It requires consecutive years and a baseline above zero. Otherwise the change is unavailable.
