特許の出願書類に「先行技術文献」を記載する意義について(2)【リライト版】
あなたの発明とその先行特許との違いを記載しておくことができます。





✔「最も類似する発明」が出願書類に記載の先行技術文献そのもの
✔あなたの発明と「最も類似する発明」との違いが十分説明されている
特許になる可能性を高めることができそうですね。
もっとも良くないのは、
✔先行技術文献を開示することを、リスクのように考えること
敢えて言えば、出願人(つまり、あなた)に対してです。
審査官が(あまり関係ない)先行技術文献を信用したとします。
それで特許になったとします。

The significance of listing "prior art documents" in patent application documents (2) [Rewritten version]
(Q) When filing a patent application, you list "prior art documents."
You are disclosing the closest prior art that you know.
It seems like there is no benefit to the applicant.
How should I think about this?
(A) Listing prior art documents is ultimately for the applicant's own benefit.
<Explanation>
I understand that this question has the following two intentions.
(1) Researching prior art documents is a hassle.
(2) Disclosing prior art documents puts you at a disadvantage in the examination of your invention.
This article answers (2).
(There is a link at the end for (1).)
■Is disclosing prior art documents a disadvantage or an advantage?
Is disclosing prior art documents a disadvantage in obtaining a patent?
Not at all. In fact, it can be considered an advantage.
Let's say you conduct a prior art search and find a proper prior patent.
You can also mention the prior patent in the patent documents.
You can mention the differences between your invention and the prior patent.
This will increase the chances of your invention being patented.
(Know your enemy.)
■ If you file a patent application without conducting a prior art search
On the other hand, what if you file an application without conducting a prior art search?
And if, as a result of the examination, you are presented with a prior patent you have never seen before...
You may not be able to argue against it at all.
The examiner will not end the examination with just prior art documents.
The examiner himself will also conduct sufficient research.
■ About the examiner's impression
The examiner will look for the "most similar invention" to the invention being examined.
(This will become "cited invention 1" in the notice of reasons for refusal.)
What if the examiner conducts a prior art search and finds the following case?
✔ The "most similar invention" is the prior art document itself that is mentioned in the application documents
The examiner will form an "impression" of the applicant.
Of course, it cannot be a bad impression.
And in your patent application documents,
✔The differences between your invention and the "most similar invention" are fully explained
This will likely increase your chances of getting a patent.
■Don't consider disclosing prior art documents as a risk
On the other hand, consider the opposite case.
The worst thing to do is
✔Consider disclosing prior art documents as a risk
Let's say you disclose prior art documents that are not very relevant.
In this case, the examiner will not form a very good impression.
I would say, towards the applicant (that is, you).
The examiner may think that you can't properly disclose prior art because you are not confident in your invention!
There is also the following possibility.
Let's say the examiner trusts the (not very relevant) prior art documents.
Let's say that you get a patent.
There is a risk that such a patent will be invalidated immediately.
Having the examiner properly examine your patent will make it a strong patent.
■The disclosure of prior art documents is ultimately for the applicant's own benefit.
I hope you found the above explanation helpful.
Appropriate disclosure of prior art documents is ultimately for the applicant's own benefit.
I hope this information is helpful.
