When the inventor has found a solution to a certain problem it is necessary to find out whether the solution is new. Therefore the invention should be compared to the descriptions of the similar solutions in the existing patent descriptions as well as descriptions in the technical publications of the particular area. Determination of the state of art provides an overview of the particular part of technical area already protected by a patent and gives directions where further steps could be taken.

In making a search it should be taken into account that generally the patent application is published after 18 months from the filing date and the utility model after its registration.
