What is the effect after the invention patent is rejected in the substantive examination stage?

First of all, it is clear that the "substantive examination stage" is a stage in the examination process of the invention patent application, which means that the invention patent application is still in the examination process.

In the process, I received the "Rejection Decision", indicating that the application for a patent for the invention was not authorized, so it was not authorized. If you want a patent application to be authorized, you need to submit an examination request within the statutory time limit, and then strive for patent application authorization. Otherwise, the application for a patent for invention has no chance to be authorized, and the legal status is "deemed withdrawn".

Secondly, this situation means that the invention patent application is not authorized, so there is no "patent right". Since there is no patent right, there is no "invalid" problem. The "invalid" in the patent law refers to the "patent right", that is, the "invalid" can only refer to the authorized patent or the authorized patent.

The invention patent application is not authorized, so there is no "invalid" problem.
