It takes 1 year and a half from application to application approval.
You can go to the local intelligence bureau (it seems to be this unit) to find out if this patent already exists.
Then find someone who specializes in writing patent applications to write patent applications for you. (It's hard to say exactly how much it costs. ) About 1000.
This is very professional, and most people can't write. Some college teachers will write this because they have the results of scientific research projects, and sometimes they have to write applications. I can't write it myself.
Then, the patent office will put your application in a place similar to an yearbook. If there is no objection, your patent will be approved within one year (if someone is already using it, you can't apply for a patent).
If your patent can be easily copied, don't apply. Before your application came down, products were everywhere.
