When does the protection of patent right begin?

The protection of patent right is a broad concept, and its core refers to the exclusive right enjoyed by patent applicants or patentees for their own inventions and creations. After the patent application is authorized, the patent right will definitely be protected. However, from the date of application to the time of authorization, the rights of patent application are also protected, but in different degrees and forms. When does the protection of patent right begin? Take the invention patent application as an example. The application is kept confidential from the date of filing until the application is published. At this stage, the protection of its rights is manifested in that after the application for a patent for invention, the application with the same theme will lose its novelty because of its conflict, and the patent right cannot be granted. This stage is a temporary protection stage from the publication of the application to the grant of the patent right. During this period, although the applicant can't bring a lawsuit against the person who exploited his invention without his permission and ban it, he can ask him to pay an appropriate royalty. If the other party refuses to pay, the applicant can exercise the right to bring a lawsuit after obtaining the patent right. At this stage, the applicant has only limited exclusive rights.
