For patent searches we use the database of European and world patents that we regularly receive on CD and DVD discs. The database contains full wording of patent documents including annotations and pictures. Updating is weekly so that we always possess the latest information on the published patents in the entire world. In addition, we also use the patent databases of the USA and Japan. This we utilize for carrying out patent searches on the any topic of science and technology. For the needs of researchers we carry out regular incremental searches and we follow the patent activity of selected companies. Since we dispose of patents since the year 1978, it is possible to make searches with a large retrospective.
