What is the entrepreneurial idea of applying for a patent?

If you want to start a business by what you invented, you can apply for a patent for it. If it's just an idea, then you can't apply for protection. If you do well, someone will imitate you. This is the case in shopping malls. Competition is normal. You should make sure to do it as early as possible, and at the same time, you should make sure to do your best to stay competitive.
