The free-of-charge search in SIP Software for Intellectual Property GmbH’s patent database search4ip is available to interested parties to give an impression of the database’s speed and the full text search (simultaneous right, left and middle truncation, brackets, proximity operators). The data contents are up to date. There is no updating of the IPC classes or changes in the help view. It s not a research tool for the daily work. We take no responsibility for the content and functionalities. This search is switched off during the year 2014.

To use a good and cheap way for patent searches, we recommend our Invention Navigator solutions. You are welcome to test the Search4ip database.
