What evidence is needed for patent invalidation, and how to submit the evidence of patent invalidation?

To declare a patent invalid, it is necessary to provide relevant evidence of the patented invention and submit the patent invalidation evidence to the the State Council Patent Reexamination Board.

After the patent right has been granted and announced by the patent administration department of the State Council, if any unit or individual thinks that the patent right does not conform to the Patent Law of People's Republic of China (PRC) and its detailed rules for implementation, it may, from the date of announcement, request the the State Council Patent Reexamination Board to declare the announced patent invalid.
