The reason, as the subject said, is that piracy is everywhere and infringement is out of the question. But if you don't want to say goodbye to others, you won't bother to get rich. But your idea does not represent everyone's idea, that is, someone uses intellectual property protection to attack your enterprise. All right, I'll make copyright registration with your work. Then take the copyright registration certificate to sue you for plagiarism and ask you to compensate for the loss. Of course, the court will accept it, but you need a long time to collect evidence to prove your innocence, and there is also a problem whether the court finds your evidence valid.
And this is just a superficial malice. What's more sinister is that you send infringement warning letters to all known customers, which will damage your reputation in the industry and make customers suspicious. If the media are invited to intervene in the exposure again, well-run enterprises will be in jeopardy immediately, or even close down directly. No, the registration fees of local copyright bureaus are generally between free and extremely low (0-300). The registration fee of the National Copyright Administration is only 3500 yuan. Of course, if you entrust an agency to handle it, the usual cost is only about 1000~2000. With so little money, an enterprise can be destroyed.
