According to the newly
published <Chinese Patent Examination Guideline 2023>, patent examiners
could examine whether utility model applications are apparently lack of inventive step,
in addition to the apparently lack of novelty. This new grounds of rejection
will officially take effect on January 20, 2024.
Some patent practitioners
believe this change shows the resolution of the CNIPA to seriously crack down
and reduce utility model patent filings, especially in view of the fact that
the CNIPA also publishes <Regulation of Patent Filing Behavior> on the
same day. Some are even of an opinion that introduction of “apparently lack of
inventive step” ground will change utility model patent prosecution into a
pseudo substantive examination, and such will likely kill a large number of
utility model applications, and they believe that the grant rate of utility
models will drop considerable in 2024.
However, we think these
opinions are over-interpretation of the impact of “apparently lack of inventive
step”. According to our prediction, the new ground just aims to target
bad-faith and low-quality utility model applications, but not intend to target bona
fide utility model filings.
As a matter of fact,
“apparently lack of inventive step” ground has already been used by the CNIPA’s
examination division since late 2022. Typically, if claims are drafted too
broad, especially if claims look like a simple combination of components well-known
in the art, the examiner may raise such a ground of rejection. According to our
observation, just like how the CNIPA raise “apparently lack of novelty” ground
against utility models in the past 13 years, examiners are not obliged to cite
any prior art when they raise “apparently lack of inventive step” rejection.
The examiner may simply issue “apparently lack of inventive step” rejection
based on his/her intuitions and feelings. This makes sense because if examiners
would have to cite prior art for raising “apparently lack of inventive step”,
such is no more a part of “preliminary examination” procedure, as required by
the utiliy model examination procedure.
According to our experience,
applicants should not worry too much about the addition of “apparently lack of
inventive step” ground against utility models, as the overall inventiveness
standard for utility models are not
changed under the new law and regulations. Utility models’ inventiveness
requirement remains to be lower
than the inventiveness requirement for invention patents. According to the
<Chinese Patent Examination Guideline 2023>, the inventive step of
invention patent applications could be assessed by one, two or more than two prior art
documents, whereas the inventive step of utility model applications could be
assessed by just one or
two prior art documents. Only when a utility model is a simple
piecing-together of prior art, its inventive step can be assessed by more than
two prior art documents. In other words, the addition of “apparently lack of
inventive step” ground in utility models will not change the fact that utility models are
easier to be allowable than invention patent applications from the perspective
of inventiveness standard.
