If you do not apply for a patent in time for your invention and creation, after other people know about your invention and creation, they will take the fruits of your labor as their own, file a patent application for your achievements, and treat them as patent rights. Then, in turn, you will sue the court or patent management agency for infringement of patent rights, which will make the original inventor's labor results unable to be used and implemented, leaving the original inventor in a passive position of being beaten.
