What is Espacenet?

Espacenet offers free access to more than 150 million patent documents worldwide, containing information about inventions and technical developments from 1782 to today. It has a user-friendly interface available in almost all European languages. It enables users with little or no experience in patent searching to obtain an overview of the state of the art, to follow new developments or to find out who invented what.

New Espacenet, a substantially revised and improved version of Espacenet with state-of-the-art features and enhanced functionality, was released in November 2019.
