特徴が２つある商品でも１つの特徴だけで特許を目指した方がいい理由【リライト版】
限定しない→何でもいいということです。
「収納部と留め金の両方に特徴があるカバン」
について、あとから他者に特許を取られる心配もないでしょう。
✔（アイデアのある）収納部が同じで、
✔（アイデアのない）留め金がわずかに異なる
そんなカバンを作ることができてしまい、十分に保護できません。
・・・収納部を有するカバン。
請求項１に記載のカバンにおいて、さらに・・・の留め金を有する。
このような請求項を「従属項」や「引用形式請求項」と言います。
相乗効果がない場合、請求項２の意味はあまりありません。
というと必ずしもそういうわけでもありません。
この点は、勘違いされることも多いのですが、
発明を限定していく（具体的な商品に近づけていく）
→限定の仕方が悪いと、特許性を高めることにはなりません。
そこで、別々の特許出願をすることになります。
つまり、収納部と留め金のいずれか一方の特許出願のみで十分です。
ただ、どのような特許を目指せばよいかが煩雑になりがちです。
弊所でもこのようなご依頼は多いです。
弊所では、過去の実績から柔軟に対応可能です。
というのが、理想です。

Why it's better to aim for a patent on only one feature even if the product has two features [Rewritten version]
(Q) Our new product is a bag with two features (a storage section and a clasp).
I would like to protect it with a patent, but how should I go about creating a patent strategy?
(A) It depends on where the idea is.
An idea is a way to solve the problems (issues) of conventional bags.
An idea and a feature do not necessarily match.
For example, some design features cannot be called ideas.
Below, we will consider ideas in the following cases:
(1) When the idea is only in the storage section (or only in the clasp)
(2) When the idea is in both the storage section and the clasp
(3) When the idea is a combination of both
■(1) When the idea is only in the storage section (or only in the clasp)
In this case, I think it would be fine to obtain a patent for the storage section.
There is not much need to mention the clasp in the patent.
[Claim 1] A bag with a storage section of...
This patent is sufficient to protect the new product.
This patent for claim 1 does not limit the configuration other than the storage section.
No limit means anything is fine.
Also, this is the case if the clasp does not have any innovative elements. In that case,
there is no need to worry about someone else obtaining a patent for a "bag with features in both the storage section and the clasp".
On the other hand, obtaining a patent for [Claim 1] A bag with a storage section and a clasp is a tricky one.
Others can easily imitate it. In other words, they could make a bag with the same storage section (with an idea) and a slightly different clasp (without an idea), which would not be adequately protected.
************************************************************
<Column>Dependent claims that increase patentability
By the way, there is a concept called a "dependent claim".
[Claim 1] A bag with a storage section.
[Claim 2]
The bag according to claim 1 further has a clasp.
You can cite other claims by saying "according to claim 1".
This type of claim is called a "dependent claim" or "dependent claim".
You can also create claim 2 for the clasp.
However, consider whether there is a synergistic effect between the storage section and the clasp.
If there is no synergistic effect, claim 2 is not very meaningful.
As mentioned above, claim 1 alone can protect the desired bag.
Is claim 2 more likely to be patented than claim 1?
But that is not necessarily the case.
This point is often misunderstood, but
limiting the invention (bringing it closer to a concrete product)
→If the limitation is poor, it will not increase patentability.
****************************************************
■(2) When the idea is in both the storage section and the clasp
In this case, you can obtain two patents.
The storage section and the clasp are considered to be separate ideas.
Therefore, separate patent applications will be filed.
However, if you simply want to protect the bag, the same as in (1) will be sufficient.
In other words, a patent application for either the storage section or the clasp will be sufficient.
However, you will need to find a way to prevent others from patenting the other feature.
■(3) When the idea is the combination of the two
This is when there is a synergistic effect by having both a storage section and a clasp.
In this case, the combination of the two is one idea.
[Claim 1] A bag with a storage section and a clasp.
This is the form we aim to patent.
************************************************************
<Column> Patents are not about "creating a product first" but about "protecting a product as a result"
It seems to be common to create a product first and then try to protect it later.
However, it can be complicated to decide what kind of patent to aim for.
Our firm receives many such requests.
Our firm is able to respond flexibly based on our past track record.
Ideally, you should aim to obtain a patent as soon as an idea is born.
And, as a result of obtaining a patent, you will be able to protect your product against widespread imitations!
At this time, it is also effective to conduct a search of prior patents.
This has the following benefits: 1. You will be able to determine what types of applications are likely to be patented.
2. You will be able to prevent infringement of others' patents.
