European patent search for your AI agent

European patent search your agent can call: find EP patent applications by words, applicant company, IPC or CPC class and date, or list a company's patents, with the EPO source and licence on every row.

The problem

You want to know what a competitor has patented, or which companies file in a technology area. The European Patent Office's search pages are built for people clicking, not for an agent that needs structured rows it can compare and count.

Where the data comes from

European Patent Office Linked Open EP data, published under CC BY 4.0. Ahel serves selected bibliographic facts from about 4.8 million EP applications: titles in English, German and French, applicants, IPC and CPC classes, filing, publication and grant dates, and the EPO register link. Every row names the weekly dataset it came from.

What is not included

No claims, full text or drawings, no legal status beyond grant, and no patents from other offices such as the USPTO or WIPO. Inventors are not included, and applicants who are private persons are shown by country only. This is not an official EPO publication; check the register link before you rely on a result.

What it costs

Each task page shows the live price, and every run is quoted before it starts. A search that finds nothing is free.
