USPTO and EPO Work Toward Joint Patent Classification System
In view of the significant benefit to stakeholders of developing a
transparent and harmonized approach to a global classification system for
patent documents in order to make the search process more effective
and in the belief that cooperation between their two offices will facilitate
progress in undertaking classification harmonization projects under the
IP5 Common Hybrid Classification initiative the USPTO and the EPO
have agreed together to work toward the formation of a partnership to
explore the development of a joint classification system based on the
European Classification system (ECLA) that will incorporate the best
classification practices of the two offices This system would be aligned
with the World Intellectual Property Organization (WIPO) classification
standards and the International Patent Classification (IPC) structure
Accordingly they have initiated discussions on governance and
operational aspects of such a partnership
The IP5 partner offices will be continually apprised of progress at
appropriate IP5 forums Stakeholders will receive regular updates on the
substance and progress of classification partnership discussions between
the two offices
October 25 2010
USPTOEPO agreement
Joint classification system based initially on ECLA
USPTO to move from USPC to CPC
EPO to move from ECLA to CPC
European Patent Office
Why did USPTO think CPC was a good idea
USPTO wanted up-to-date classification scheme (IPC-based)
EPO had classified US documents back to 1920 into ECLA
EPO and USPTO decide to create a new system based on ECLA

Lessons learnt (1)
CPC has a 2000-series aka indexing codesminus these codes are for additional information onlyminus often they are really helpful in combination with
main trunk symbols
CPC has breakdown codesminus if there is a relevant CPC symbol check for the
corresponding 2000 codeminus A63B 24 rarr A63B 2024minus A63B 43 rarr A63B 2043minus in alternative browse the interleaved presentation

Why did USPTO think CPC was a good idea
USPTO wanted up-to-date classification scheme (IPC-based)
EPO had classified US documents back to 1920 into ECLA
EPO and USPTO decide to create a new system based on ECLA

main trunk symbols
CPC has breakdown codesminus if there is a relevant CPC symbol check for the

Lessons learnt (1)
CPC has a 2000-series aka indexing codesminus these codes are for additional information onlyminus often they are really helpful in combination with
main trunk symbols
CPC has breakdown codesminus if there is a relevant CPC symbol check for the
corresponding 2000 codeminus A63B 24 rarr A63B 2024minus A63B 43 rarr A63B 2043minus in alternative browse the interleaved presentation
