Introduction and Background
The pre-CPC age

The pre-CPC age
•The International Patent Classification(IPC)–the international and well acknowledged
standard;
儿童焦虑症的表现
–Strasbourg Agreement: any office signing the
agreement shall publish its patent documents with
IPC symbols
•The IPC (70K subdivisions) is insufficient to meet the needs of big patent offices, which need more
–subdivisions;
–flexibility;
–fast implementation
4
The pre-CPC age (continued)
Domestic classification systems exist that offer an alternative to the IPC –ECLA/ICO at EPO, –FI/FT at JPO, –USPC at USPTO •None of the systems covers all the documentation

The pre-CPC age (continued)
•The Patent Offices and ur community strive to
achieve a "global" classification system capable to accommodate the needs of all
–Harmony (Trilateral) Project was launched in 2000 to harmonize ECLA, USPC and FI into IPC –IPC Reform in 2006

Foundation Project is launched in 2008 to extend the original trilateral cooperation to the IP5 offices •Yet a faster implementation of a global classification scheme is needed

USPTO and EPO Work Toward Joint Patent Classification System
"In view of the significant benefit to stakeholders of developing a transparent and harmonized国际象棋规则视频
approach to a global classification system for patent documents;in order to make the arch process more effective; and in the belief that cooperation between their two offices will facilitate progress in undertaking classification harmonization projects under the IP5Common 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 bad 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 apprid of progress at appropriate IP5 forums.
Stakeholders will receive regular updates on the substance and progress of classification partnership discussions between the two offices."

•
USPTO/EPO agreed to co-operate on a joint classification system bad
initially on the IPC-bad ECLA (October 2010)•
USPTO to move from USPC to CPC •

EPO to move from ECLA to CPC •
CPC planned to be bi-laterally

CPC scheme
•In one scheme, CPC will include:
–the former ECLA (~140K entries)
–the former ICO (EPO indexing codes)
职业技能培训网–the most important KW (EPO controlled keywords)
migrated to ECLA or ICO
–G06Q scheme for Business Methods being refinedit s amazing
so as to incorporate former USPC 705 subdivisions
(about 375 subdivisions vs. 50 currently available in
ECLA/IPC)
–US special collections and digests
–Y ction of ICO
