Espacenet , patents

Espacenet (external link) is an online service to search for patents and patent applications in more than 90 countries. The database provides free online access to the full text of the patents.


It is also worth considering the Derwent Innovations Index (external link) when you are searching for patents (access only permitted within the domain). Espacenet can then be used to access the full text. If necessary, you should supplement your search with professional research carried out by specialists at a patent office (ip-search (external link)). 


Access to Espacenet is also possible outside of the domain. If you have any technical problems or questions about access rights, please contact the Database Helpdesk.


Courses are held by appointment. They explain the various search strategies and features using specific examples.
