History
date IPC CPC
1971 Strasbourg Agreement
2006Jan
IPC Reform• "invention" vs. "additional"
information• "advanced" vs. "core" level• reclassified documentation• additional layer of the IPC
(Definitions)
2010Oct
bilateral agreement EPO-USPTO for the launch of CPC
2011Jan
Simplified IPC Reform• classification in "full IPC" vs.
"main-group only" instead of "advanced" vs. "core" levels

Governance and operations
IPC CPC
IPC Union members, under the supervision of WIPO
EPO & USPTO
operations are described in the CONOPS documentation
operations are described in the CPC OPS documentation
Committee of Experts (IPC/CE)
meetings are physically held yearly at WIPO
CPC Implementation Group (CPC IG) to hand over to CPC Joint Board (CPC JB) in operation phase (July 2013)
meetings are (physically or VICO) held quarterly/monthly
6
Governance and operations (cont'd)
IPC CPC
IPC revisions are expected to take place yearly
CPC revisions are expected to take place up to monthly
revisions are worked out by the Revision Working Group (IPC/WG)
meetings are physically held twice a year at WIPO
revisions are worked out by the Joint Editorial Board (EB)
meetings are (VICO) held weekly
7
Documentation coverage
IPC CPC
almost all of worldwide published patent documents after 1975 (entry in force of the Strasbourg Agreement)
minimum PCT documentation available in EN, FR, DE (and NL)
+ whole of US patent documentation
+ CPCNO allocations: EPO member states can send their allocations in CPC format, to retrieve them later in EPOQUE

Scheme availability

• www.uspto.gov/web/patents/classification/index.html
• worldwide.espacenet.com/classification

IPC scheme layout
Sections A-H
• 631 subclasses• ~ 71 000 symbols• invention or additional information
Indexing codes• additional information only• as a rule numbering starts at 101/00
– but C07D main groups start at 201/00 ...

CPC scheme layout
Sections A-H Section Y
Main trunk• 647 subclasses• ~ 160 000 symbols• invention or additional information• {...} used to distinguish CPC text from IPC one
• 6 subclasses• ~7 300 symbols• including former
USPC "XRAC's and digests"
• tagging of emerging cross-sectional technologies
• additional information only
Indexing codes ─ 2000 series• ~ 82 000 symbols • former "breakdown" and "orthogonal" ICO• include IPC indexing codes• additional information only
11
Y a.k.a. the 9th section of the scheme
IPC CPC
ideas over a 9th section of the IPC, to cover emerging technologies, cross-sectional in the sense that the new schemes would span over many schemes of the A-H sections, was explored at the time "Nanotech" was discussed in the IPC
"Nanotech" was the trigger to have in ECLA the 9th section for tagging of emerging technologies
later Y01 (Nanotech) was moved to B82Y
the 9th section of the IPC could not be created because of the high IT impact on certain offices
Y section stays in CPC for tagging of emerging cross-sectional technologies
now includes also former USPC XRAC's and digest (Y10S)
12
Definitions availabilityIPC CPC
• www.wipo.int/ipcpub • www.cpcinfo.org• www.uspto.gov/web/patents/
classification/index.html• worldwide.espacenet.com/classification
Definitions are "one click away" next to the IPC symbol they relate to
Definitions are expected for all subclasses (except indexing schemes) and main-groups, at least
Definitions are currently available as XML/PDF files at subclass level
a D marks their availability in the IPC page a D marks their availability in the espacenet page
available also on USPTO classification resources
plan to have all IPC subclasses (except indexing ones) covered
currently ~1/3 of the total is ready
plan to have all of CPC subclasses (except indexing ones) and main-groups covered
all ready by mid 2013
13
Definitions layout
IPC CPC
a Template exists to structure information in the best way
XML schema mirrors the Template structure
a Template exists which is almost identical to the IPC one
XML schema is compatible with the IPC one
14
What / where / how to classify
IPC CPC
the IPC Guide provides the required information on the proper usage of the IPC
the CPC Guide does not exist (yet),but the CPC follows IPC Guide"unless differently stated"
what: contribution over the prior art; other features interesting for search ...
where: function-oriented vs. application-oriented places ...
how: invention vs. additional information; indexing schemes ...
what: contribution over the prior art; other features interesting for search ...
where: reflect IPC practice to a very large extent, unless differently stated in the CPC Definitions

Database
IPC CPC
MCD• the master database for the IPC,
collecting allocations sent by all offices worldwide
• MCD is the authoritative source of the IPC classification data
• it also generates reclassification working lists (RWL) for all offices at each IPC revision
CPC-DB• a "dual master" database with
synchronization, to ensure independence of operations of the two offices, while offering refreshed access to the shared allocations
• CPC-DB is the authoritative source of the CPC classification data
• database "products" are not exported from CPC-DB but from the local databases, e.g. DOC-DB/XML is fed by DOC-DB

• “Dual master" databases with data synchronization• CPC-DB will be the authoritative source for CPC classification data

Revisions
IPC CPC
yearly (ready 6 months in advance)
worked out by the IPC/WG
up to monthly (ready 6 weeks in advance)
worked out by the CPC EB
platform: IPC IEF platform: CPC collaborative environment
the following deliverables are expected:• Scheme / Definition project changes
– en français aussi !• CRL (cross-reference list)• Compilation of changes
– stems from the two above• RCL (revision concordance list)• RWL (reclassification working lists) for
all participating offices• CI (Catchword Index)
