Search for similar registered inventions

Before the inventor files an application for the registration of a utility model, it would also be useful to investigate yourself whether the invention is new and whether it has an inventive step.

This can be done by examining the existing inventions from all relevant sources. Examples of inventions include existing patent descriptions, utility model descriptions, and other technical publications in the field. Determining of the state of the art also gives an indication of which part of the technical field is already protected and in which direction it is possible to proceed.

When performing a search, it must be taken into account that, in general, the patent application is published only 18 months after it has been filed and the utility model is published after it has been registered.
