Identification of the problem domain

Pegging is critical for the novelty of the final results, but it is also time consuming and difficult. The best results will be produced using both traditional and modern methods of knowledge acquisition, that is, conducting several parallel lines of activities, the results of which will be integrated. 

All these traditional processes of learning are usually recursive that is, we may need to repeat them several times until we are able to proceed to the next activity, which could be called patent search. A patent search usually results in a number of patents related to our problem domain. We may find only several such patent or tens or even hundreds of them. In practical terms, we will be able to focus on a maximum of between five and ten patents, and we need to select them from all found patents. This can be done using various selection criteria, for example only the most recent patents or only the patents from a specific country. In the United States, the most important are American patents because our own inventions and the related patent claims will be examined and compared with the inventions behind these patents. 

Identify all major concepts, including their names 

Identify names of symbolic attributes associated with these concepts 

Compare available patents, preferably in terms of the used patent claims (symbolic attributes) and their values
