2013. 7 Special feature : Considerations for patent classification

Current status and issues of patent classification

Osaka Institute of Technology
5-16-1 Ohmiya, Asahi-ku, Osaka, 535-8585, JAPANAbstract: In order to examine and search a large number of patent applications, patent classification is indispensable. International Patent Classification (IPC), FI,F-Term have been used for many years.
However, because of the globalization of the economy and the development of technology, there is a limit to the IPC. Now, CPC (Cooperative Patent Classification) has been started by EPO and USPTO and CHC (Common Hybrid Classification) is discussed among 5 big patent offices.
The history, current status of patent classifications and challenges of the future are outlined.

It was expected that the Project would harmonize each office’s internal classification scheme (FI/F-term of JPO and CPC of EPO/USPTO) and would make International Patent Classification (IPC) more detailed. The JPO has also been using its resources to advance CHC Project. However, the progress is not very good. Furthermore, the IP5 offices are trying to replace CHC into a new framework to make IPC more detail. This paper explains the current situation and the future of CHC Project.

This article explains the overview of CPC such as the background of introducing new classification system, the relationship between CPC and ECLA, ICO, USPC etc. CPC has helped examiners and patent information users to search patents efficiency, on the other hand patent information users should not rely on CPC only in conducting patent searches because the detailed operation about CPC isn’t revealed now.

Nakai Bldg. 6-25-4 Honkomagome Bunkyo-ku, Tokyo 113-0021 JAPANAbstract: CPC (Cooperative Patent Classification) which took effect in January 2013 will have significant impact on patent searching. It is important for patent searchers to understand how CPCs are implemented on patent databases in order to secure correct search results. In this article, we describe coverage of CPC in patent databases on STN and also explain specific search and display options. Online thesaurus of CPC, available on STN, can facilitate searching the new patent classification codes. Finally, various tips on using patent classification in patent searching are summarized.

Until now, the USPTO had been using the highly unique United States Patent Classification (USPC). With the start of the CPC, it can be said that the USPTO compromised to a classification system that follows the International Patent Classification (IPC). The EPO and USPTO hope to eliminate duplicated work and share information. Also, in understanding the classification system and determining the research classification, there should be a reduction in burden for the general user. In the future, it is suggested that there may be a certain influence on IPC reform. Here we give a general overview of the events leading to the CPC system, a summary of the classification system, browsing the classification table, a search strategy, etc.

Problems of patent classification in Japan

Yuichi USUI
INFOSTAAbstract: I explained about the procedure of grant of patent classification in Japan. I also explained the relationship between patent classification relevant to technology and patent examination room. I showed that the IPC of 0 hits number is caused by the lack of concordance between the IPC and FI. I also demonstrate some examples that the IPC is more fragmented than FI. For problems of classification imparting such, it was pointed out that should be searched around the FI・F term also. I pointed out that maintenance of FI・F term is important as well.
