特許を取るのは難しいか？【リライト版】
特許を取るのは難しいか？
結論としては、
✓①イメージとしては「思うほど難しいものではない」
✓②実務上は「難しいかどうかを判断した上で、特許を出せます」
この２点についての詳細と、関連事項をお伝えします。
より正確には「産業上利用できる発明」です。
つまりその発明がまだ知られていないことです。
改良を試みたり、あるいは、しばらく寝かせておくこともできます。
このことは、特許の審査官にとっても、とてもありがたいことです。
特許を取るためには、審査官に審査してもらいます。
✓特許を取る難しさと、特許の経済的価値・市場価値とは異なります。
「特許権の有効性・無効性について争いになるリスクがある」

Is it difficult to obtain a patent? [Rewritten Version]
■ Is it difficult to obtain a patent?
Is it difficult to obtain a patent?
In conclusion,
✓① In general, "it's not as difficult as you might think."
✓② In practice, "you can file a patent application after determining whether it's difficult or not."
We will explain the details of these two points and related matters.
■ (Related Matter 1) Requirements for Patentability
(1) Let's say you have created an idea.
That idea must be an "invention" that is eligible for a patent.
More precisely, it must be an "industrially applicable invention."
The question is whether that invention can be the subject of a business.
If it's an idea for a "product," it almost always qualifies as an industrially applicable invention.
This is because manufacturing, selling, importing, etc., it becomes a business.
(2) To obtain a patent, the invention must have novelty and inventiveness.
✓ Novelty of an invention means that the invention is new.
In other words, the invention must not yet be known.
✓ Inventive step means that the difference from publicly known inventions is significant.
(This judgment is one of the most difficult in the world of patents.)
■ "You can file a patent after determining whether it's difficult or not" (②)
Before filing a patent, you can conduct a patent search on publicly known inventions.
This makes it easier to determine whether obtaining a patent is difficult.
If it's difficult, you can temporarily postpone filing the patent.
You can try improvements or let it sit for a while.
■ If you prepare properly, obtaining a patent is "not as difficult as you think" (①)
If you prepare properly, obtaining a patent is not as difficult as you think.
All that's left is to prepare the appropriate patent application documents and submit them to the patent office.
Select inventions that are likely to be patented and prepare appropriate patent application documents!
This is very helpful for patent examiners.
■ (Related Matters 2) Patent Examination
To obtain a patent, your invention must be examined by an examiner.
A procedure (request for examination) is necessary to have your invention examined.
Incidentally, I was involved in the examination of around 1000 patents during my time as an examiner.
■ (Related Matter 3) The Value of a Patent
✓ The difficulty of obtaining a patent is different from the economic value/market value of a patent.
✓ There is also this perspective on the value of a patent:
"There is a risk of disputes regarding the validity or invalidity of the patent right."
Conducting a patent search before filing a patent also increases the value of the patent.
