    IPC a sound tool for Environmentally Sound Technologies?

    Slide 2:? 1994: UNFCCC UNFCCC - EST technology inventory: http://unfccc.int/ttclear/jsp/Technology.jsp ? 2008: GB initial proposal in project WG020 (> project C456): to establish IPC indexing scheme based on UNFCCC inventory, to assist: Access to EST Technology transfer Statistical analysis, monitoring EST Identify technology trends "Patent landscapes"

    Outline of IPC EST relations The initial GB proposal wasaiming at linking the EST technology inventory with the IPC. The initial proposal tentatively linked some entries of the inevntory with existing codes. Still the GB proposal also called for a seperate indexing schemeThe initial GB proposal wasaiming at linking the EST technology inventory with the IPC.

    Slide 3:IPC WG favors "Catchword Index" type inventory of EST related IPC symbols EP also proposes indexing scheme for alleged EST effects EP has also cooperation with UNEP,.. EP has internal EST project (see later slides)

    Slide 4:What is "environmentally sound" ? " - protect the environment, - are less polluting, - use all resources in a more sustainable manner, - recycle more of their wastes and products, and - handle residual wastes in a more acceptable manner than the technologies for which they were substitutes." " - mitigate climate change - support adaptation to climate change"

    Criticism The definitions of "environmentally sound" are taken form UN and UNFCCC documents (see Annex 8 of C456).The definitions of "environmentally sound" are taken form UN and UNFCCC documents (see Annex 8 of C456).

    Slide 5:IPC describes technical concepts and should not assess/describe alleged effects/benefits Comparative effects ("less polluting") are vague and may change with time Patent examination does not verify claimed benefits, only assesses novelty and inventive step, i.e. the grant of a patent does not assure that the claimed benefits are achieved ! Classification based on such (subjective) judgments may lead to wrong conclusions, interpretation as a quality seal!

    Criticism

    Slide 6:No need for new indexing scheme IPC comprises places for all relevant technical subject matter in regular places If not yet: create new additional regular places for new emerging technology Moreover: if new EST technology emerges, one should create regular IPC places for that anyway and not only indexing places ! Reclassification problem for backfile, e.g. workload Limited use if applied only to frontfile

    Criticism

    ? Optimum: All documents pertaining to specific technical area (concept) are found

    Slide 7:What to achieve in search ?

    ? < > Efficiency: no irrelevant documents This slide is meant to remind the audience of the different aspects of a search and the competition between recall and precision.This slide is meant to remind the audience of the different aspects of a search and the competition between recall and precision.

    Slide 8:Why classification?

    Language independent Terminology / jargon independent Concept search Standardized application to documents by experts Available for (old) patent documents where no full text of claims / description is available ? Advantages of using IPC in comparison to only term / keyword searching: This slide is meant to remind of the advantages using classification codes for tagging patent documents and adding value in this way to databases. Using classification codes for search will improve both recall and precision. In the end, the question will be if the proposed modifications of EPO will improve both recall and precision.This slide is meant to remind of the advantages using classification codes for tagging patent documents and adding value in this way to databases.

    Slide 9:Regular <> Indexing symbols

    Regular IPC symbols: - describe "concept", i.e. specific subject matter - usually defined by concatenated titles of several hierarchical levels, - i.e. by aggregations of several "keywords" Indexing IPC symbols: - describe one additional aspect by one symbol - like adding one additional keyword This slide is meant to compare shortly regular IPC codes and indexing codes. Some in the audience may not be fully aware of that. In the end, the EPO approach does not really propose indexing codes; as a matter of fact, each of the new symbols (see below) rather defines a rather complex concept.This slide is meant to compare shortly regular IPC codes and indexing codes.

    Slide 10:EPO approach

    New "indexing" entries, to be developed step by step for different areas of EST; similar to EPO nanotech scheme Soon for "energy generation", "energy storage", e.g. Y02E 10/00 Energy generation through renewable energy sources Based on existing EPO internal classification tools: - ECLA codes - ICO codes - Controlled Keywords I.e. new codes = "Queries" composed of existing ECLA, ICO, CK Y02E 10/00 = f(ECLA, ICO, CK) This part of the presentation is based on selected information obtained by the EPO (H Wongel; C Kallinger) The new EPO indexing codes for EST are developped by and by for different areas of EST because of considerable workload. They are, in essence, not describing new EST techniques but only new "abbreviations" for combinations of existing ECLA, IKO, CK codes. Each new code is a symbol for a specifci search query using at least oen but frequently several This part of the presentation is based on selected information obtained by the EPO (H Wongel; C Kallinger) The new EPO indexing codes for EST are developped by and by for different areas of EST because of considerable workload.

    Slide 11:EPO approach

    new EST codes: Yabc xx/yy = f(ECLA, IKO, CK) e.g. Yabc xx/yy = ('ECLA1' OR 'ECLA2' OR 'ECLA3') AND 'ICO1' AND 'CK1' Is not true indexing scheme, rather represents concepts

    Slide 12:EPO approach

    New codes are only coding (re)combinations of existing ones; I.e. there will be no new codes describing aspects not yet covered by existing codes Applied automatically to ECLA classified backfile via relation to existing codes Application to frontfile: Automatic similar to backfile. Also intellectually in individual cases. The new EPO indexing codes for EST are developped by and by for different areas of EST because of considerable workload. They are, in essence, not describing new EST techniques but only new "abbreviations" for combinations of existing ECLA, IKO, CK codes If one wishes to achieve high recall and precision it takes tiem to elaborate proper combiantionsThe new EPO indexing codes for EST are developped by and by for different areas of EST because of considerable workload.

    Slide 13:EPO approach

    Utility for other users outside EPO ? Because of use of ECLA, ICO, CK, the algorithms behind each new code are not applicable in databases containing only IPC Is, however, interesting analysis of EST concepts by using concepts defined by queries (ECLA, IKO, CK) Would allow to define similar or refined standardized EST concepts using only IPC and keywords (language limitation) But: Does this improve examiner's search efficiency ? Or, Does it simply add stable/refined concepts for statisticians ? The new EPO indexing codes for EST are developped by and by for different areas of EST because of considerable workload.

    Slide 14:C456 approach

    WG proposal: Inventory based on existing IPC codes relevant to EST as part of Catch Word Index To be developed if approval by CE Based on UNFCCC inventory ? Broader than that ? As compatible as possible with that ? Seek cooperation in order to improve UNFCCC inventory?

    Slide 15:Last but not least

    Again: Does one need additional true indexing scheme for alleged effects? e.g. "reduced energy consumption" Remember: IPC knows indexing for alleged therapeutic effects, which are never verified but simply alleged by inventor
