This is what you can expect from the free semantic search:

With this free service, we make an innovative online tool available, which can help you with regular patent work in the R&D department.
In order to present you with extensive, up-to-date information, we base our search on a broad database of more than 100 agencies and institutions which is updated weekly.
After quick and easy registration, you can simply enter the descriptive text (in English), keywords or publication number you’re looking for in the search field. The relevant results will be displayed straightaway.
In a full text portrait with all important bibliographic information, you can examine the search results in detail and check the current legal status of the publication. A personal folder in the account allows you to save documents for later access.

We hope to welcome you to our online platform in the future.
