The map uses one NUTS edition (NUTS 2021); the UK is shown at NUTS-1 because its codes do not convert to NUTS-2.Berlin shows 5,387 here and 6,085 in the Berlin report: the report counts families with a Berlin applicant or inventor, the map inventor families only, and the report uses first-filing years 2019–2024 where the map uses EP filing years 2019–2023.

Nine methodology guides and the SQL of every figure are published with the report.

Checked before release

Each report passes 16 quality checks, then a subject expert and a second person sign it off.

Data stays in the EU

PATSTAT runs in the EU region of Google BigQuery; the site and connectors run on our own servers.

Accessible

Built to WCAG 2.2 AA by the team that holds the accessibility framework contract of the German Federal Ministry of the Interior.

Clients include BVMed. Our TIP training was first given at the PATLIB Conference 2026 in Warsaw.

Bring us your question.

A 15-minute call is enough to know whether a report, a training or the toolchain fits, and what it costs.
