1. In the beginning

　There are several types of technical classifications, but there are two types of patent classifications unique to Japan: "FI", which is a subdivision of the internationally used IPC, and "F-term", which classifies technical features. There is.And there is another type, "CS term" for searching non-patent documents.

　This CS term can be found on the J-PlatPat F-term page.However, I couldn't find a detailed explanation, so I tried to find out what kind of configuration and how many terms there are.

XNUMX. XNUMX. CS term configuration

XNUMX What is a CS term?

　With the remarkable development of software technology in recent years, the JPO has revised the operational guidelines and examination standards for examination of computer software-related inventions, collected documents of computer software-related technologies other than patent documents, and constructed a database. We have developed a CS term to search the literature contained in the database.
　Like the F-term, the CS term is an index that represents technical features, such as "theme code (alphanumeric characters) 9 digits starting with theme group 2A" + "viewpoint (alphanumeric characters) 2 characters" + "number XNUMX characters". It will be written.

　Originally, it was an "F-term-like classification" for examiners to search for computer software-related technical documents on the examiner's terminal, but with the addition of J-Platpat functions, it has become available to the general public. It was.

9 Actual CS term (001AXNUMX)

　First, let's look at the actual CS term. It comes out first in J-PlatPatTheme code "9A001"Consists of 2021 terms and is categorized by perspective. (Numbers are terms: As of March 3, 16)

　If you look at the viewpoint classifications in the list, you will see two of the same classifications (hardware, etc.).
　The one above (eg BB) is given to the main theme of the literature, and the one below (eg BZ) is given not to the main theme but to related matters.

XNUMX Other CS terms

　In J-Platpat's "F-term simple display", the theme group "9ASelect "" to see a list of CS term theme codes.Looking at each one, it seems that there are differences in the situation of perspective arrangement depending on the theme, as there are only theme codes and some have no terms set.Therefore, the presence or absence of terms and the number of terms are summarized as follows. (As of March 2021, 3)

　As you can see, some had terms and some did not. Compared to "9A001", the number of terms is overwhelmingly small. The CS term has a short history since it was developed, and the number of terms is still small, so I hope that it will increase further and become more convenient in the future.

　By the way, looking at the theme code list earlier, all the themes other than "9A001" were newly established in 28.Speaking of 28, it was the time when the FI was revised and the F-term maintenance (theme integration / division, re-creation of the F-term list, etc., and the creation of new themes, etc.) was carried out, and at the same time, it was the latest. It seems that maintenance of the CS term was also carried out according to the computer software technology trends of.

XNUMX. XNUMX.Try to search

　Let's actually search with J-PlatPat.

　Searching for "9A001BB01" as "F-term" on the "Patent / Utility Model Search" page found more than 1 non-patent documents.If you open the searched document appropriately and look at the bibliographic information, you can see that several terms in "2A9" are given.

　Also, if you include patent gazettes in the search range, this will actually be a hit as well.However, it seems that only the theme "9A001" and domestic publications are supported so far.Other than that, it didn't hit.Even so, if you search for a patent with "9A001", you may find a patent gazette that was difficult to search with the conventional F-term.

XNUMX.in conclusion

　There wasn't much information published about CS terms, but I tried to organize them within the scope of the search. Since the CS term is a term that searches the literature like an F-term, I think it will not be difficult if you can understand the F-term.Also, since some of them support patent search, it will be very convenient if they can be used for patent search in the same way as F-term, so I hope that this will be realized.
