Combined CPC/FI Introduction into the IPC

Antonios Farassopoulos

Head of International Classifications and WIPO Standards Service

Global IP Infrastructure Department

February 2011

introduction
Introduction
  • IPC not detailed enough for the searching needs of several Offices and of the public
  • Some Offices have developed more detailed local Classification systems, based on the IPC (ECLA, DEKLA, FI) or not (USPC)
  • ECLA, FI are regularly updated in all technical fields. They cover almost the totality of PCT min
  • EPO USPTO agreed to a common Classification based on ECLA (CPC)
introduction3
Introduction
  • Search using the IPC possible in all international and national databases
  • Consultation of local Classifications available only in local databases
  • Syntax particular for each one, not always clear
  • Search using local Classifications possible for the public only in respective local databases
introduction4
Introduction
  • Since ten years efforts for harmonization and development of the IPC could not meet the expectations
  • Main problem the need for intellectual reclassification of the back file and the lack of corresponding resources.
proposal for a detailed integrated ipc
Proposal for a detailed integrated IPC
  • Integrate the CPC and FI subgroups into the IPC in parallel (new e- and j-groups)
  • CPC and FI subgroups when integrating into the IPC should follow IPC rules and conventions

e.g. - common numbering system

- “others” subgroups in FI will not be introduced, instead hierarchically higher groups will be used

  • Symbols from both CPC and FI will be presented in “Int.Cl” field on patent documents. Provision of additional one letter code in ST.8 will differentiate between CPC and FI symbols
  • Subsequent harmonization will be carried out within the current framework of IP5 CHC and IPC/CE afterwards

When resources for reclassification become available, these parts could be introduced into the common trunk groups.

choice of offices
Choice of offices
  • Offices will select to classify their documents either in the common trunk groups only, or in e-groups / CPC or in j-groups / FI
  • e- and j- groups will not be rolled up to common trunk

C main groups only

E e- or ct groups (CPC)

J j- or ct groups (FI)

reclassification during transition
Reclassification during transition
  • Families classified in CPC: automatically transferred to common trunk and e-groups
  • Families classified in FI: automatically transferred to common trunk and j-groups
  • When an office decides to use e- or j- groups, it will reclassify those documents that have not been reclassified by the family propagation above with its own rhythm (incomplete reclassification indicated in the warnings of e- or j- groups)
  • Families having in both e- and j- symbols will keep both types of symbols
timelines
Timelines
  • e- and j- groups are introduced in one go in parallel. Two to three years are needed to adapt CPC and FI to the IPC, adapt IT systems, publication etc.
  • CHC project will harmonize e- and j- parts afterwards
future revision procedure in areas including e and j groups
Future revision procedure in areas including e- and j- groups
  • Revision of CPC or FI without impact on the common trunk by the offices owners of the CPC or FI respectively.
  • Quality checking of new scheme using accelerated procedure only electronically and within a limited period of time (e.g. one month) by IB assisted by editorial board
  • Harmonization of e- and j-groups in order to be included into the common trunk will follow the current IP5 CHC – IPC/CE approach.
  • Revision of large areas (e.g. subclasses, main groups) will follow the current IPC/CE approach.
    • However revision procedures should be simplified.
    • New approaches should be considered.
advantages
Advantages
  • No need for major intellectual reclassification during the integration phase. All offices can make the best use of detailed classification systems promptly and according to their resources.
  • Public users have a global picture of classification systems in one scheme and can search using only one type of symbols in one field (i.e. IC) in any database.
  • Examiners will learn easier than in the current situation j- and e- groups (e.g. using the parallel display). Such better knowledge will lead to easier revision or harmonization in the future.
  • Once all CPC/FI subdivisions are integrated into the IPC, search efficiency will be improved especially in areas where the current number of subdivisions in the IPC is insufficient.
drawbacks
Drawbacks
  • Need to include systematically ct, e- and j- symbols in a query in order to achieve complete search for the world wide documentation. However this is already the case today in a much more complicated way.
  • Some confusion (reform, simplification, ?) for external users, although first reaction seems positive.
