Patent agency for postgraduate entrance examination

To tell the truth, if it's just for the postgraduate interview, it won't cost that much, and even if it's available now, even this postgraduate interview may not be in time this year. The application time of invention patent is 1 year, and it may not be approved yet. And as long as you don't go to a special school, once you write that you have a patent, the interview teacher will pay close attention and keep asking patent-related things. If your words are irrelevant, it will give a bad impression. I have only seen my brothers and sisters apply for patents in order to get a national scholarship or to register in Shanghai and Beijing.
