IPC objectivesIPC objectives
6. The Classification […] has as its primary purpose the establishment of an effective search tool for the retrieval of patent documents by intellectual property offices and other users […]
7. The Classification, furthermore, has the important purposes of serving as:
(a) an instrument for the orderly arrangement of patent documents in order to facilitate access to the […] information contained therein;
(b) a basis for selective dissemination of information […]; (c) a basis for investigating the state of the art […]; (d) a basis for the preparation of industrial property statistics […]

Classification objectivesClassification objectives
• Arrangement of objects• in a one dimension space
(shelves, shoe boxes, …)• To Facilitate access to the objects
or• To dispatch these objects
(e.g. to examiners)• Other use: (simple) description of
contents - one viewpoint

11.[…] Changes to the structure of the Classification and to methods of its revision and application were needed in order to ensure its efficient and effective use in the electronic environment.
• Binded to classification approach• One dimension space (shelves)• No real use of boolean capabilities
• Very expensive update procedure• Frequent updates• Need to reclassify

IPC reformIPC reformClassification approachClassification approach
• Adapted to arrange collections• Limited for describing contents• Need to differentiate:
• Documents• Concepts describing the contents
• Concepts can be arranged in a different classification
• The example of Japanese F-terms

13. The following major changes were introduced […]: (a) the Classification was divided into a core and an
advanced level, in order to better satisfy the needs of different categories of users;
• Convenient for storing documents according to size of collections
• Complex for searching

documents are reclassified according to the amendments to the core and advanced levels;
• Very costly as changes are very frequent

IPC reformIPC reformConclusionConclusion
• Look for stable solutions • to reduce costs
• Differentiate the classification of• Documents (storing, dispatching)• Concepts (indexing)
• Mr Iwasaki’s conclusion:
Future: Super IPC (multi-dimensional viewpoint) ??

Overall ConclusionOverall Conclusion
• Recognize the role and constraints of each player
• Reduce costs• Enhance cross-linking
through:• Exchange of viewpoints & expertise
(WIPO, IPOs, PDG, PATCOM)• Standards (WIPO – SCIT – Standards &
