Through Lib4RI, you have access to a large number of databases. You can filter the list by topic or alphabetically and find a brief description of each of the databases.
The database hosted by the German Patent Office provides access to the full-text of all German patents from 1877 onwards. The website is available in English and German. DEPATISnet also covers other major and several minor patent offices, but not nearly as many countries as esp@cenet.
Note that you can download the full-text images as PDF files, but only page by page.
The Derwent Innovations Index searches more than 14 million patent records, many with links to the full-text. Patents are from 40 worldwide patent-issuing authorities including the U.S. Patent and Trademark Office, the European Patent Office and the Japanese Patent Office. Searches retrieve records from 1963 to the present, but coverage varies among patent authorities. Derwent divides patents into 3 broad areas: chemical, electrical & electronics, and engineering. Abstracts of patents are rewritten to make it more apparent whether or not a particular patent would be applicable to your work. In addition, the database contains citing and cited patents and literature references, allowing users to move both forward and backward in time.
Note that Derwent Innovations Index is accessible via Web of Science.
Open databaseThe dfv zentral archiv (in German only) of the dfv media group offers you access to facts and specialist knowledge to more than 800,000 articles from over 35 specialist publications.

The database offers full text for most of the dissertations added since 1997 and strong retrospective full text coverage for older graduate works.
