Recently the State Intellectual Property
Office of China has officially published the revised Patent Examination
Guidelines which will become effective as of July 1, 2006. The following are some
highlights of the revision that may lead to certain changes or clarification
regarding patent prosecution in
practice.
| 1. |
Time point for filing divisional application(s) on the applicant's own initiative
|
a.
|
According to the law, so long as
an application is pending or within two months after the date of the grant
decision, the applicant is entitled to file divisional application(s) from the
application.
|
|
b.
|
Upon receipt of a rejection decision,
the applicant is entitled to file divisional application(s) within three months
regardless whether or not a request for re-examination is duly filed with the
Patent Re-examination Board (the PRB);
|
|
c.
|
During the re-examination procedure
at the PRB or even during the appeal procedure before the court for not
satisfying with the re-examination result of the PRB, the applicant is entitled
to file divisional application(s) from the application.
|
|
d.
|
In addition to the above time points
(a. b. and c.), there is a specified restriction on filing a divisional
application based on a divisional application. To file a further divisional
application based on a divisional application, it is a precondition that the
first parent application as initially filed in China is either in a status of
pending or within two months of the date of grant decision. In other words, if
the first parent application has been announced a patent or abandoned, it is
not acceptable for the applicant to try to divide its divisional application
into further divisional application(s) on his/her own initiative.
|
|
e.
|
Any divisional application duly
filed at an examiner's objection to the unity of the application will be
accepted without a consideration of the above mentioned precondition of the
status of the parent case. That is, it is possible for the applicant to file a
further divisional application based on a divisional application if the unity
of the divisional application is protested by the examiner, even when the said
first parent case has been issued or withdrawn

Treatment for double
patenting
| The Chinese Patent Law does not
allow double patenting for one invention. If there are two identical applications
co-existing at the SIPO and one of them has been issued a patent, the applicant
will be requested to make a choice and a statement to declare to maintain one
of the two cases when the second case is examined and is to be granted.
According to the current practice, the applicant may make a statement stating
that the previously granted patent will be abandoned on the date when the
second case is granted. However, the new Guidelines request that the applicant make
a statement that the previously granted patent is abandoned since the filing
date of the previous application, if he/she would like to maintain the later
granted case and abandon the previously allowed one.
|
|
As a matter of fact, it is the
case that some of applicants take a strategy to co-file two applications for
the same invention at the beginning, one for a patent for invention and the
other for a patent for utility model, aiming to get an earlier grant by way of
utility model and also to get a searched and examined patent by way of patent
for invention. And later on they will have the previously granted utility model
abandoned once they are requested to make their option to maintain one case
when the later case is found patentable and identical with the previous one. It
is also the case that a divisional application is filed within two months upon
the parent application is granted when the granted patent is found not perfect
and needs to be modified or corrected. We believe that the new regulations
should be taken into account when adopting such a strategy of co-current filing in
terms of enforcement of the patent right..

Software-related patent applications
|
(1)
|
It is explicitly stipulated
that it is not necessary for a solution relating to computer program to include
the change of computer hardware.
|
|
(2)
|
A claim, which merely relates
to an algorithm or rules of mathematical computing, is not patentable for the
reason that it falls into the category of rules and methods for mental
activities.
|
|
(3)
|
A claim, which is defined not
only by the features of rules and methods for mental activities, but also by certain
technical features, should not be considered as rules and methods for mental
activities as a whole, and its patentability should not be excluded in
accordance with Art. 25 of the Patent Law.
|
|
(4)
|
A computer-related invention
is a patentable subject matter when it constitutes a technical solution only. A
technical solution refers to such a kind of solution that is adopted to resolve
a technical problem by using technical means and can produce technical effects.
|
|
(5)
|
Generally, it is accepted by
the new Guidelines that the claim for product may be defined in the way of means
plus functions corresponding to each step of the corresponding process claim of
a computer software invention, and in this way, the claimed product would be
considered as a solution consisting of these functional modules fulfilled by
the computer program, rather than a physical entity which implements the
solution by way of hardware.

|
Chance for argument before being rejected
|
The Guidelines prescribe that
normally a rejection decision would be made after at least two office actions
if the case is found not in a condition of being allowed. Especially if the
applicant's response to the first office action includes amendment to the
application document, a second office action should be issued upon
consideration of the amended document before a rejection decision would be
issued. By this specified rule, even for some prudent applicants, it may be
worth while to try to use the chance to argue for their applications in
response to the first office actions by filing amendment to the applications
before surrender, as there will be a second office action in the light of the
arguments and amendment.
|
|
|
5.
|
Publication (Art. 22 of
the Patent Law)
|
It is clearly specified that the
publication in internet consists of disclosure of publication and is bar to the
novelty of the same invention.
|
|
|
6.
|
Exception of lack of
novelty
|
Under Article 22 of the Chinese
Patent Law, China adopts absolute novelty requirement in terms of publication
while relative novelty in terms of use or knowledge that is made public by
other way than publication. It is explicitly described in the new Guidelines
that displaying in an exhibition held in a foreign country does not constitute
disclosure while the publication of the invention spread during such an
exhibition will raise a bar to the novelty of the same invention.
|
|
|
7.
|
Sufficient disclosure of chemical
inventions
|
Sufficient disclosure is
emphasized in the new Guidelines. It sets forth the requirements in detail for
the full disclosure for either the invention for chemical product, for chemical
process or for usage of chemical product. New embodiments or new
experimental/test data filed after the filing date for overcoming insufficient
disclosure issue will not be considered. For a new use of a known compound, the
description shall set forth
experimental data/test date for proving said use and effect.
|
|
|
8.
|
Unity of invention of Markush claims
|
The unity requirements used to be set
forth as: "All the Markush elements should meet the following standards: (1)
all alternative compounds possess a common property or activity; and (2) all
alternative compounds possess a common structure, i.e. they share a common main
structure unit; or under the circumstances that they do not have a common
structure, all of the alternative compounds are regards as belonging to the
same class of chemical compounds in the relevant technology of the invention".
They are replaced by the following provisions in the new Guidelines: "All the
Markush elements should meet the following standards: (1) all alternative
compounds possess a common property or activity; and (2) all alternative
compounds possess a common structure, which common structure constitutes a distinguishing
feature between the present invention and the prior art and is absolutely
necessary for the common property and activity, or under the circumstances
that they do not have a common structure, all of the alternative compounds are
regarded as belonging to the same class of chemical compounds in the relevant
technology of the invention."

9.
|
Examination on the gene
engineering related inventions
|
The new Guidelines set forth in
detail the regulations for examination of gene engineering applications in the light
of the special natures of the invention in the field.
|
|
|
10.
|
Restoration for request for
re-examination
|
It is explicitly acknowledged that
if the request for re-examination or the payment concerned is somehow
considered officially not in conformity with the formality requirements, it is
possible for the applicant to restore the re-examination request by making up necessary
steps.
|
|
|
11.
|
Time limit for evidence provision
during the invalidation procedure
|
It is clearly set forth that the
time limit for the petitioner to supplement evidence is within one month from
the date when he/she files the petition for invalidation. The evidence
submitted after the one-month period will not be considered by the Panel.
|
|
|
12.
|
New regulations for the petition of
correction of search report with respect to a utility model patent
|
There is a new procedure for the
patentee of a utility model to request for correction of a search report where
any mistake like the following is found. That is, (1) a mistake among the data
of bibliographic information or the characters is found, (2) the procedure of
making the search report is found inappropriate; (3) the regulations of laws
applied thereto are found inaccurate; (4) the fact on which the preliminary
conclusion is made is wrong; or (5) there exist other mistakes that should be
corrected. The patentee can raise the correction requirement within two months
from the date of receipt of the search report.
|
|
|
13.
|
For a PCT application, electronic form
of sequence list without hard copy in paper is acceptable
|
In summary, the new
Guidelines set forth more flexible and operative requirements for formalities
or preliminary examination of patent applications. For formalities, it goes in
conformity with the international trend of "applicant-friendly" and is quite encouraging. For the substantive
examination, it provides clarification for quite a few vague points that used
to be uncertain for the applicants and makes the substantive requirements
standardized and easier to be followed.
