Patent withdrawal refers to the applicant withdrawing
the patent application from the CNIPA after filing the patent
application but before the granting of a patent right. There are
two types of patent withdrawal: active withdrawal and passive
withdrawal.
After filing the application but BEFORE the granting of
a patent right
The emphasis here is on the time range of the withdrawal:
1)The first point in time, after filing the patent
application
Filing an application is like a formal way to establish an
official relationship between applicant and patent. Although the
relationship is established before the CNIPA, the applicant still
has the freedom to dump patent application at any time, that is, to
withdraw the patent application.
