Patent talks about cooperation

First of all, you can't apply for a patent on China Applied Technology Online, because the patent is accepted and authorized by China National Intellectual Property Administration. In other words, you can only apply for a patent to the State Information Bureau or entrust an agency to help you apply. Call you to talk about cooperation, you should be alert. A large part of them are liars. Usually, they will ask you to pay for identification, search and so on. And ask you to pay gradually. Be careful.
