PATSTAT Explorer

Interactive patent analysis on PATSTAT, built for the EPO Technology Intelligence Platform (TIP) JupyterHub and maintained with the EPO Academy and the PATLIB TIP Working Group.

Quick start

The only file you need is PATSTAT_Explorer.ipynb.

1. Download it from this repo (or File → Save Link As… on the raw link
2. Upload it to your home directory on the EPO Technology Intelligence Platform.
3. Open it, click into the code cell, and run it (play button, Shift+Enter, or Menu → Run → Run selected cell).

The notebook installs and starts everything for you. A clickable link appears when it's ready. First run takes 1–2 minutes.

The notebook starts three local services (a schema-discovery helper, a Python API, and the web app) on your TIP JupyterHub environment. You never touch them directly.

What it does

PATSTAT Explorer has two ways to start an analysis and two standalone tools.

Start an analysis

• Applicant Search — find an organisation by name. PATSTAT stores many name variants for the same company (SIEMENS AG, SIEMENS LTD, SIEMENS CORP). The app auto-suggests which variants belong together and lets you group them as a single entity before you dive in.
• Technology Search — type a CPC code (H01M) or a plain-English description (battery) and see the top applicants filing in that technology area. Click an applicant to drop into the same deep-dive.

Deep-dive (opens when you pick an applicant)

• Overview — filing trend over time, top jurisdictions, top CPC technology fields.
• Network — who files patents together with this organisation.
• Citations — which technologies the organisation cites and which technologies cite back.
• CPC Map — a heatmap of how the portfolio spreads across CPC sections, revealing technology overlaps.

Standalone tools

• Country Comparison — chart patent filings for a set of countries (DE, US, CN, JP, KR, …), optionally filtered to a technology.
• AI Query — if the built-in views don't answer your question, ask in plain English and Claude writes the SQL for you. Bring your own Anthropic API key.
