Systematic introduction of graphic illustrations in the IPC Summary prepared by the International Bureau 1. At its 18th session, the Working Group had decided to start six pilot projects (projects M 600 to M 605) covering six subclasses with Brazil, Mexico and Spain as rapporteurs. Rapporteurs were invited to submit comments on the preliminary guidelines to project WG 171 after the completion of the pilot projects. 2. Brasil, Japan, Spain, the United States, and the EPO have submitted comments. The comments not only relate to the guidelines but address the future ways of handling this task in general, i.e. beyond the pilot projects. This issue should be discussed and settled before agreeing on amended guidelines. The IB has undertaken to prepare this short summary that may serve as a basis for discussions. 3. When reviewing the different statements, the following options appear to emerge: (a) Continuing the task of introduction of graphical illustrations in the framework of Dprojetcs. Advantage: (i) Selection and introduction requires specific expertise regarding the technical subject matter covered by a place. Technical experts will have to be heard; but the rapporteur should also have some knowledge of the field. Aquiring such knowledge requires considerable effort. Therefore, rapporteurs of D-projects may be qualified because they have to become aquainted with the subject matter anyway when preparing the definitions. (ii) Furthermore, illustrations were already considered as valuable parts of definitions when the initial concept was devised of what definition should be and what they could contain. (iii) Moreover, the illustrations - like the definitions - will also be part of the illustrative and informative “electronic layer” of the IPC. Bringing together the developments of its different components into one project would only be logical. Drawback: This approach will further increase the burden on rapporteurs of definition projects and their scope. For the time being, D-projects focus primarily on subclasses while the illustrations would be primarily for groups. Thus, definitions could be delayed further. Completed D-projects may have to be reopened. (b) Continuing in the framework of M-projects; however, at a first stage one should identify those areas of the IPC which need such illustrations instead of systematically going through all of them. Advantage: The work of selecting suitable material is limited to those areas of the IPC that would need illustrations. More effort could and should be invested in researching or establishing additional illustrations because it appears that the currently available illustrations are of limited usability for the IPC. Drawback: Criteria for determing areas needing illustrations would have to be determined and all places would have to be checked. Such analysis would require already quite specific knowledge of the subject matter or experience in the field. Already such prior selection process would consume additional effort and complicate the task additionally. (c) Continuing as before with systematically going through the submitted collections and selecting suitable illustrations.
