Technical knowledge in its entirety, including relevant patents, is a valuable economic asset and indispensable for innovative enterprises.


This priceless expert knowledge cannot primarily be found in scientific publications but in patent documents. Experts estimate that about 70% to 90% of all scientific knowledge published is exclusively contained in patent documents. 


FIZ Karlsruhe collects patent and legal status information provided by the respective patent offices and combines it on one single search platform.
