IPC Revision in Practice EPO 8 February 2010
MCD revision life-cycle 3-6 months before entry into force Load Revision Concordance List (RCL) and Valid Symbols File (VSF) (received from WIPO) Create & distribute working lists to officesaccording to agreed algorithm for work-sharing Just prior to entry into force Store results from Offices (with auto deactivation) Automatic reclassification of one-to-one correspondences After entry into force Store any further results received Distribute residual working lists as required
General findings Revisions prior to 2009 • IPC completeness in MCD ~ 80-95% Bigger revisions of 2009 and 2010 • figure can be significantly less • Systematic approach needed • for complete elimination of residual lists • i.e. ensure reclassification of all documents
Aspects of completeness Various causes for incompleteness: • new documents arrive in MCD between creation of working lists and entry into force • some offices (e.g. EPO) base reclassification on their own schemes • a different view of scope • stored number formats can differ • documents can be missed • family composition in MCD may differ from that in other offices • i.e. different interpretation of priority • incorrect data stored in MCD
EPO approach Planned EPO method 2 years after a revision enters into force(ensure complete processing of the EPO working lists) • select all documents from the WL not yet reclassified • send to examiners for classification in ECLA • when complete, generate new IPC symbols from ECLA (for all documents in the WL) • de-activate all remaining IPC symbols to be revised
Proposed QCTF approach Proposal by the MCD Quality Control Task Force:(part of project QC002) • After initial reclassification period • working lists "opened up" for all offices • offices can also reclassify families not in their own working lists • after a fixed period • "automatic" reclassification of remaining documents • e.g. assign higher-level symbol
Possible solutions for the future • real-time reclassification • move away from exchange of data in batches (xml files) • time-consuming • inhibits flow of information • Enable reclassification of individual families in real-time • more dynamic involvement • to greater completeness over a period of time • WIKI ? • allow wider access to MCD data in some kind of WIKI environment • may increase number of people actively reclassifying • helps to fill gaps
