What is the legal status of patent? What does it mean to be rejected after an application for a patent for invention is published? Please explain to me, hero.

If your patent is rejected, then your patent application is not passed! But you don't have to worry. If you think your patent is practical, novel and creative, you can submit a reexamination application to the Patent Reexamination Board within 3 months after receiving the rejection notice! If the reexamination board still rejects it, you can also submit an application to the people's court within 3 months from the date of receiving the notice!
