According to article 45 of the PRC Patent  Law, starting from the date of the announcement of the grant of the  patent right, any entity or individual who considers that the grant of  the said patent right is not in conformity with the relevant provisions  of this Law, may request the Patent Reexamination Board to declare the  patent right invalid

Pursuant  to article 46, the Patent Reexamination Board shall promptly review the  request, make a decision on it, and notify the requester and patentee.  The decision declaring the patent right invalid shall be registered and  announced by the patent administration department under the State  Council.

Upon  the Patent Reexamination Board declaring the patent right invalid or  the decision upholding against the patent right, the party can take the  dispute to the People’s Court within three months from the date of  receipt of the notification. The People's Court shall notify the  interested parties to the invalidation procedure to participate in the  proceedings.

Pursuant  to the paragraph 1 of article 47, any patent right which has been  declared invalid is treated as non-existent from the beginning.
