The International Classification of Patents, created for conforming the systemization of patent documents, has not yet reached its objective. The same documents are indexed in different ways by each signatory country of Strasbourg's Agreement. The objective of this paper is to present the subjective causes involved mainly in the processes of categorization and indexation that are important stages to allow that the users of a patent system can retrieve the technological information contained in these intellectual property assets. The research was based on bibliographic review and documental search.
