Part III Chapter 1 Eligibility for Patent and Industrial Applicability
Chapter 1 Eligibility for Patent and Industrial Applicability
(Main Paragraph of Article 29(1) of the Patent Act)
1. Overview
The main paragraph of Article 29(1) of the Patent Act defines that any person who has made an invention which is industrially applicable may obtain a patent therefor. Article 2(1) of the Patent Act defines "invention" as "the highly advanced creation of technical ideas utilizing the laws of nature". An invention which does not comply with this definition shall not be patented. An invention for which a patent is sought shall be industrially applicable even if the patent complies with this definition, since the purpose of the Patent Act is the development of industry (Article 1).
The main paragraph of Article 29(1) of the Patent Act provides the two following points as the patentability requirements:
(i) A statutory "invention" (hereinafter, referred to as "eligibility for a patent" in this chapter) (see 2.)
(ii) An "industrially applicable invention" (hereinafter, referred to as "industrial applicability" in this chapter) (see 3.)
This chapter explains determination on eligibility for a patent and industrial applicability.
In this chapter, an invention complying with the requirements of eligibility for a patent is referred to as a statutory "invention". The word "invention" in the expression "claimed invention" does not mean that the invention complies with the requirements of eligibility for a patent.
2. Determination on Requirements of Eligibility for Patent
The subject of determination on the requirements of eligibility for a patent is a claimed invention.
When a claimed invention is considered as any of (i) to (vi) in 2.1 , an examiner shall determine that the claimed invention does not comply with the requirements of eligibility for a patent. For a claimed invention utilizing computer software, see 2.2 .
When there are two or more claims in the claims, an examiner shall determine
on requirements of eligibility for a patent for each claim.
The expression "highly advanced" in the definition of the statutory
"invention" has been introduced to differentiate the "invention" from "device" under the Utility Model Act. Thus, an examiner may disregard this expression in determining eligibility for a patent.
2.1 List of Subject Matters Not Corresponding to Statutory "Inventions"
To be considered as a statutory "invention", an invention needs to be a "creation of a technical idea utilizing the laws of nature". Since (i) to (vi) shown below are not a "creation of a technical idea utilizing the laws of nature", it is not considered as a statutory "invention".
(i) The laws of nature as such (see 2.1.1)
(ii) Mere discoveries and not creations (see 2.1.2)
(iii) Those contrary to the laws of nature (see 2.1.3)
(iv) Those in which the laws of nature are not utilized (see 2.1.4)
(v) Those not regarded as technical ideas (see 2.1.5)
(vi) Those for which it is clearly impossible to solve the problem to be solved by any means presented in a claim (see 2.1.6)
2.1.1 The laws of nature as such
Since a statutory "invention" shall utilize the laws of nature, the laws of nature as such, like a law of preservation of energy or a law of universal gravitation, are not considered as a statutory "invention".
2.1.2 Mere discoveries and not creations
Since a statutory "invention" shall be a creation, mere discoveries, such as discoveries of natural things (e.g., ore) or natural phenomena, for which an inventor does not create any technical idea with intention, are not considered as a statutory "invention".
However, if things in nature such as chemical substances or microorganisms have been isolated artificially from their surroundings, those are creations and considered as a statutory "invention".
2.1.3 Those contrary to the laws of nature
If a matter necessary to specify a claimed invention (hereinafter referred to as "a matter specifying the invention" in this part) involves any means contrary to the laws of nature like a law of preservation of energy (e.g., the so-called "perpetual motion"), the claimed invention is not considered as a statutory "invention".
2.1.4 Those in which the laws of nature are not utilized
When a claimed invention is considered as any of (i) to (v) shown below, the claimed invention is not deemed to utilize the laws of nature, and thus, is not considered as a statutory "invention" (see Examples 1 and 2).
(i) Any laws other than the laws of nature (e.g., economic laws)
(ii) Arbitrary arrangements (e.g., a rule for playing a game as such)
(iii) Mathematical formula
(iv) Mental activities of humans
(v) Those utilizing only (i) to (iv) (e.g., methods for doing business as such)
Even if a part of matters specifying the invention stated in a claim utilizes the laws of nature, when it is determined that the claimed invention as a whole does not utilize the laws of nature, the claimed invention is deemed as not utilizing the laws of nature (see Examples 3 to 6).
On the contrary, even if a part of matters specifying the invention stated in a claim does not utilize the laws of nature, when it is determined that the claimed invention as a whole utilizes the laws of nature, the claimed invention is deemed as utilizing the laws of nature.
The characteristic of the technology is to be considered in determining whether a claimed invention as a whole utilizes the laws of nature.
(Examples of those contrary to the laws of nature)
Example 1: Computer programming languages (applicable to (ii) in the above)
Example 2: A method of collecting money for an electricity bill or a gas bill etc., by rounding off the total amount to be collected to the nearest 10 yen unit (applicable to (v) in the above)
Example 3: A method of plying a container vessel to transport a large amount of beverages from a region where crude oil is expensive and beverages are inexpensive to another region where crude oil is inexpensive and beverages are expensive, and after unloading the beverages, transporting a large amount of crude oil instead of beverages to the homeward voyage
Example 4: A method of billboard advertising using utility poles, characterized by forming in advance groups A, B, C, D, ... with a prescribed number of poles in each group, placing a holding frame to post thereon a billboard for each pole, and posting the billboards in each group on holding frames placed to poles in each group in circulation in a certain time interval
Example 5: A method of playing shogi (Japanese chess) between players remote from each other, the method comprising: a step of transmitting a move of one player to the other player through a chat system in the one player's turn; and a step of transmitting a move of the other player to the one player through the chat system in the other player's turn, the steps being repeated alternately
(Explanation)
It does not fall under “the invention” since the method described above applies only artificial arrangements as a whole where two players remote from each other play alternately although the chat system is used as the technical means.
