自分で特許を出す?弁理士に依頼する?損益分岐点は?【リライト版】
✓高度な特許調査を行ってくれる
✓高品質の特許出願書類を作成してくれる
✓ムリ・ムダ・ムラのない特許戦略になる
ただ、一定の費用が掛かるというデメリットがあります。
そのうえで、ご自身で特許を10件出せば、モトが取れるはずです。
あなたが弁理士と同じ知見・経験を得ないといけません。
そのためには、膨大な時間が掛かることでしょう。
ただこの費用は、あなたの膨大な時間を節約するための費用!
そう考えることができます。

①(必要な時間)×②(あなたの時間単価)で計算できますね。
弁理士試験だけなら、1000~3000時間くらいでしょうか。
→あなたは1万時間×1万円で1億円稼げることになります。
→1億円を失うことと同じです。
✓社長様の時給を3千円とします。
✓特許の書類を作成する時間も、この1000時間に入れちゃいましょう
そうすれば、モトが取れるかも知れませんね。
✓特許の手続きは、弁理士(特許事務所)に依頼しましょう!
ご自身で特許を出されて、後から弊所に駆け込まれた方も多いです。
みなさん最初から特許事務所に依頼すればよかったとおっしゃいます。

Should I file a patent myself? Should I ask a patent attorney? What is the break-even point? [Rewritten version]
Are you wondering whether to file a patent yourself or ask a patent attorney?
The benefits of asking a patent attorney are as follows.
✓ They will conduct advanced patent research
✓ They will prepare high-quality patent application documents
✓ It will be a patent strategy that is free of strain, waste, and inconsistency
However, there is a disadvantage that it costs a certain amount of money.
If you file a patent yourself, the advantages and disadvantages are the opposite.
So what should you do?
In conclusion,
✓ If you plan to file 10 patents, you can file a patent yourself.
First, gain the same knowledge and experience as a patent attorney.
If you then file 10 patents yourself, you should be able to make a profit.
Below are the reasons. It should help solve your worries.
■ The cost of a patent attorney is a cost to save you time
If you are going to file a patent, you want it to be a patent that is free of strain, waste, and inconsistency.
It is natural to want to get the benefits of hiring a patent attorney as mentioned above.
What would you do if you were to do this yourself?
You would have to gain the same knowledge and experience as a patent attorney.
To do this, it would take a huge amount of time.
In other words, if you hire a patent attorney, it will cost you a certain amount of money.
However, this cost is just to save you a huge amount of time!
You can think of it that way.
■How much can you earn while gaining the same knowledge and experience as a patent attorney?
How much can you earn while gaining the same knowledge and experience as a patent attorney?
You can calculate this by multiplying ① (time required) by ② (your hourly rate).
① Time required
Let's think about the time it takes to gain the same knowledge and experience as a patent attorney.
It is generally said that it takes 10,000 hours to become an expert in a certain field.
For just the patent attorney exam, it would be around 1,000 to 3,000 hours.
② Your hourly rate
Are you a business owner (president) who wants to apply for a patent? As long as an individual inventor runs a business using patents, he or she is the same as a business owner (president).
Let's say your hourly rate as the president is about 10,000 yen.
In that case, while filing the same patent as a patent attorney would...
→You will earn 100 million yen (10,000 hours x 10,000 yen).
On the other hand, if you do not hire a patent attorney and instead gain patent knowledge and file a patent yourself...
→It is the same as losing 100 million yen.
■If you plan to file 10 patents, you can file the patent yourself
The above estimates are high, so let's think about the lower limit.
✓Let's say the time spent on the patent attorney exam is 1,000 hours,
✓Let's say the president's hourly rate is 3,000 yen.
✓Let's include the time spent on writing patent documents in these 1,000 hours.
In that case, 1,000 hours x 3,000 yen = 3 million yen.
While you are hiring a patent attorney, you should be able to earn at least 3 million yen.
On the other hand, if you ask a patent attorney for one case, it will cost around 300,000 to 350,000 yen.
If you file for a patent yourself, file 9 to 10 patents.
That way, you may be able to make a profit.
■Ask a patent attorney (patent office) to handle the patent procedures!
What do you think?
Thank you for bearing with me through this brain teaser up to this point.
To sum up,
✓Ask a patent attorney (patent office) to handle the patent procedures!
Our firm specializes in serving individuals.
Many people have filed patents themselves and then come to our firm later.
Everyone says they should have asked a patent office from the beginning.
Are you still unsure whether to file for a patent yourself or ask a patent attorney?
We hope this information is helpful.
