XNUMX. XNUMX.Introduction

　The composition of chemical patent gazettes is different from that of mechanical patent gazettes, and I think that it may be difficult for those who read mechanical patent gazettes.We hope that understanding the structure of chemical patent gazettes will help improve your peer review.
(This column is intended for those who have read mechanical patent gazettes but have never read chemical patent gazettes.)

XNUMX.Comparison of the composition of patent gazettes

　The differences between the chemical system and the mechanical system in the structure of the patent gazette will be explained by comparing the respective embodiments and examples.

　There are the following differences between "Embodiment" and "Example", so let's organize them.

Embodiment:An indication of how the invention is implemented to the extent that a person skilled in the art can implement it.
Example:Results of conducting experiments based on the embodiment (data of experimental results etc. are described)

* In the case of mechanical systems, there are many cases where there are no examples, and in the case of chemical systems, embodiments and examples are often a set. (The use of examples in a chemical system is as follows: (XNUMX) It clearly shows that the invention can be carried out in a field where it is difficult to guess the manufacturing method from the structure of a substance such as a chemical substance, and (XNUMX) The effect of the invention is used as an example. There are reasons such as using it to prove it).

XNUMX-XNUMX Mechanical system configuration

　In mechanical patent gazettes, multiple embodiments are often listed.
　The basic embodiment is described first, followed by another applied embodiment.

　Japanese Patent Application Laid-Open No. 2009-139312 (U-Tech) will be explained as an example.　

　First, in the first embodiment (FIG. 1), which is a basic embodiment, the time display means 6 (light emitter 7 in FIG. 6) that informs the time by color and the minute display means 13 (in FIG. 8) that informs the minute. It is composed of the light emitting fan shape display 6) on the upper right.
　After that, the applied embodiments are shown.For example, in the second embodiment (FIG. 7), the minute display means 8 is a light emitter 16 on the outer circumference of the dial.
　In this way, a plurality of embodiments are listed in the order of the basic embodiment and the applied embodiment.

XNUMX-XNUMX Structure of chemical system

　On the other hand, in chemical patent gazettes, they are often written in the order of "embodiments-> examples", and in this embodiment, many "compounds that may be used as constituents of the invention" are listed. It is common to have.

　This will be explained using Japanese Patent Laid-Open No. 2002-201300 (Saitama Rubber Industries) as an example.

　In the invention of this publication, a resin composition sheet is prepared using a resin composition containing a thermoplastic resin, rubber, an inorganic filler, etc., and the resin composition sheet is adhered to a metal steel sheet to prepare a reinforced metal steel sheet.

　Then, in the embodiment, what kind of compound may be used as a thermoplastic resin, rubber, an inorganic filler, etc., which are constituent elements of the invention, is shown.

　Furthermore, in "Examples", the contents of actual experiments and measurement data are shown.Here, a resin composition sheet is prepared in "Example 1", and a steel sheet adhesion test is performed in "Example 2" and thereafter.

　In this way, compared to mechanical patent gazettes, chemical patent gazettes contain a wider range of compounds from claims to examples.Therefore, there is a problem that it is difficult to understand what kind of compound is mainly used.To understand the compounds listed in the Chemistry Gazette, you need to read them step by step.

XNUMX. XNUMX.How to read chemical publications

　As for how to read the chemical patent gazette, I think it is better to read in the order of "TAC (Title, Abstract, Claims)"-> "Examples"-> Embodiment.
　First get an overview with TAC, then read the examples where the structure of the compound is clearer (skip embodiments).If you still don't understand, go back to the embodiment and read it.

　Based on the above, let's read Japanese Patent Application Laid-Open No. 2002-201300 (Saitama Rubber Industries).

　Looking at the abstract and claims, in the present invention, a resin composition sheet is prepared using a resin composition containing a thermoplastic resin, rubber, an inorganic filler, etc., and bonded to a metal steel plate to form a reinforced metal steel plate. You can see that it will be made.
　In addition, claim 3 specifically states that the thermoplastic resin is specifically an ethylene-methacrylic acid copolymer.

　Next, looking at Example 1,

Thermoplastic resin:	Ethylene / methacrylic acid copolymer resin (Nucrel, DuPont)
Crosslinkable rubber:	Rubber with a number average molecular weight of XNUMX (XNUMX, JSR)
Adhesive agent:	Aromatic modified terpene resin (YSTOXNUMX, Yasuhara Chemical)
Foaming agent:	ks (Sankyo Kasei)

Is used.

　If you are looking for an "ethylene / methacrylic acid copolymer resin and tackifier composition", you do not need to read the embodiments as they are shown in the claims and examples.
　However, if you are looking for "composition of ethylene / methacrylic acid copolymer resin, silicone rubber, and tackifier", silicone rubber is not shown in the examples, so check if silicone rubber is shown in the embodiment. To do.

　Looking at the rubber of the embodiment, silicone rubber is shown, and it was found that the present invention corresponds to "composition of ethylene / methacrylic acid copolymer resin, silicone rubber, and tackifier" including the description in the text. It was.

　When reading the embodiment, you can read it efficiently by looking at the element you are looking for.

XNUMX.in conclusion

　This time, I wrote the basic structure of chemical patent gazettes and how to read them.
　By understanding the structure of chemical patent gazettes, you will be able to read only the necessary parts, and you will be able to peer-review efficiently.
　Since the writing style of the examples also differs depending on the applicant, we hope that you will read various publications and improve your experience points.
