Patent documents, published by national, regional or international Patent Offices, contain information about inventions for which a patent is being sought or has already been granted, or for which a utility model has been registered. Each year, more than one million patent documents are published worldwide. Studies have shown that only a small proportion of inventions are described in sources other than the patent literature. This is why patent information is such an indispensable means of acquiring knowledge about the state of the art, vital for driving forward innovation processes

The formal search for patents is usually carried out with the patent number or patent applicant or inventor.
The thematic search includes the search for terms from title, abstract, full text.
In addition, classifications should be taken into account in a thematic search. The most frequently used classification is the International Patent Classification (IPC).
