- Abstract
- The patent documentation at the European Patent Office (EPO) is organized according to the 120.000 subdivisions of the EPO's internal classification scheme (ECLA). In some fields, indexing schemes such as In Computer Only codes (ICO) provide additional ways of accessing the documentation. To meet the needs of patent examiners it was decided to develop a new DOCumentation TOOL (DOCTOOL). This tool would make it possible for examiners to enter their indexing codes directly online at their workplace and would, in addition to the existing ECLA and ICO schemes, also provide the possibility to assign keywords and free text to documents
