Cooperative Patent Classification - CPC • The USPTO and the EPO agree to co-operate on a joint classification system based on ECLA (October 2010). • What this means for the EPO: • Improve file and document routing • Saving resources on (re-)classification of US documents in the future • Opportunity to clean up and better document our classification • Common base for future classification revisions • CPC promotes IP5 CHC project • EPO will share control over CPC • Renumbering of ECLA will be needed (IT, examiner training, etc) • Resources needed for quality monitoring and training

  3. Cooperative Patent Classification - CPC • What this means for the USPTO: • Moving to an IPC-based classification system • No need to reclassify the US backfile • Enhanced access to non-US documentation • CPC promotes IP5 CHC project • USPTO will share control over CPC • Resources needed for • IT • quality monitoring • training • The USPTO and the EPO agree to co-operate on a joint classification system based on ECLA (October 2010).

Transition from ECLA to CPC Classification CPC will include: • All ECLA/ICO titles and active subdivisions (one-to-one match) • Hierarchical structure of ECLA • Capability to expand (for future revisions) • As many digits after the “/” as needed CPC will use IPC type numbering; i.e. ECLA letters after the “/” will be replaced by digits, e.g. • H01L21/0211 instead of H01L21/02A1 • H01L21/02112instead ofH01L21/02A1B EPO will propose a conversion algorithm from ECLA symbols to CPC symbols EPO may maintain, during a transition period, a one-to-one match between CPC numeric and ECLA alpha-numeric formats USPTO and EPO will jointly present and promote CPC

  5. Timeline of plans for classification activities • Training material based on FCRs shared with USPTO • IT changes at USPTO and EPO • Make CPC IPC-compliant • Freeze of ECLA revision by July • Getting ready for launch of the CPC • Phased introduction of CHC • Training • Training pilot with the USPTO • IT upgrade at USPTO and EPO • ECLA housekeeping • EPO examiners develop detailed Field-Specific Classification Rules (FCRs) in around 600 fields • Agreement on integration of CPC and FI into IP5 CHC Jan 2011 Jan 2012 Dec 2012 CPC and the FI/Fterms introduced into the CHC Freeze on ECLA scheme revisions Start of project discussions with USPTO Launch of CPC
