I applied for a patent. Can anyone else do it?

If you apply for a patent, it may not be authorized. The patent application needs to be examined after it is passed before it can be authorized; If authorized, others may be prohibited from using, selling or manufacturing. Within the validity period, but you need to defend your rights yourself, which also requires a certain cost. In addition, even if your patent is authorized, others can go to court to apply for invalidation. If your patent is invalid, you can't ban others from using it.

The patent system is to encourage inventions, give inventors a monopoly right for a certain period of time, and let them exchange publicity for protection. Otherwise, everyone hides his invention, which is not conducive to social development. Every patent has a clear scope of protection, which is determined by the claims when the patent is approved. The patent claim consists of several claims, each of which can determine a protection scope, and the technical scheme within this protection scope is monopolized by the patentee.
