NAME OF HON'BLE JUDGE: The Hon'ble Justice Prathiba M Singh
CASE TITLE: Boehringer Ingelheim Vs The Controller of Patents
What is scope of divisional application in a Patent? What
are the criterion for evaluating, where an applicant for Patent can be said to
be entitled to a divisional application?
What are basic requisites for a parent application, on the basis of
which amendment of the same can be filed resulting into divisional Patent
Application?
This Appeal dealt with similar issue. The Appeal was filed
against order dated 25.03.2022 by the Ld. Controller of Patent where the
request for the Petitioner in relation to divisional application bearing
no.20178031279 dated 04.09.2017, titled ‘A medicament of a DPP inhibitor was
rejected by the Controller of Patent on the grounds inter alia that the
divisional application was having similar claims.
Background of this case was that the Petitioner filed
National phase application on 14.11.2008 with 18 claims , in which the
Petitioner filed first amendment application in reply to first examination
report and proposed to delete all claims except claim no.14,15 and 15A.
Subsequently in the year 2016, 2 more amendment applications
were filed, which were there after sought to be converted into divisional
application in the 2017. The controller of Patent rejected this application on
the ground that the same are beyond the scope of originally filed claims.
Reasons for rejecting the divisional application was mainly
on the grounds that since the original amendment applications have already been
disallowed by the controller, the divisional application could not have been
allowed, which were filed on the basis of amendment applications earlier filed.
Question before the Hon'ble Court was that whether the
divisional applications can contain the claims which were not there in the
parent application?
The Relevant Section which takes care for the situation,
where divisional application may be filed, is Section 16 of the Patent Act
1970. The relevant portion of the same is extracted as under:
"Section 16 Power of Controller to make orders
respecting division of application
(1) A person who has made an application for a patent under
this Act may, at any time before the grant of Resultantly the provisions of
Commercial Court Act 2015 were held inapplicable to the subject matter suits.
the patent, if he so desires, or with a view to remedy the objection raised by
the Controller on
the ground that the claims of the complete specification
relate to more than one invention, file a further application in respect of an
invention disclosed in the provisional or complete specification already filed
in respect of the first
mentioned application.
(2) The further application under sub-section (1) shall be
accompanied by a complete specification, but such complete specification shall
not include any matter not in substance disclosed in the complete specification
filed in pursuance of the first mentioned application."
Sub section 2 of Section 16 of the Patent Act 1970 provides
that complete specification of such divisional Patent Application shall not include any matter not in substance
disclosed in the complete specification filed in pursuance of the first
mentioned application.
Thus the Divisional Application can not contains any claims
which were not disclosed in the Patent Application, on the basis of which the
same was filed.
The other two conditions for filing such amendment
application for divisional application is that the amendment must be by way of
disclaimer or correction and that the same must be made in order to include
facts. Other amendment can not be allowed while filing divisional Application.
As in the Divisional Application, the Plaintiff claimed
products patent , which were not in the original patent specification, the same
was rightly rejected.
In the Original Patent Application there were Claims 1 to 18
claims. These claims were wither use claims or method claims. There was not even a single product claim in the entire
set of claims filed originally.
By introducing amendment for divisional application, the
Applicant introduced 25claims.The same were Claims 1-11, 14-18, 20-25 .These
subsequently amended divisional patent application, these product patent claims
were introduced in the divisional patent application.
Another important
aspect regarding filing of Divisional Application is unity of invention. Section
10(5) of Patent Application provides for this. The same is reproduced as under:
10(5) The claim or claims of a complete specification shall
relate to a single invention, or to a group of inventions linked so as to form
a single inventive concept, shall be clear and succinct and shall be fairly
based on the matter disclosed in the specification.
It means if specification of the parent application only
shows single invention or multiple invention resulting in single inventive
concept, in that case also divisional application can not succeed.
For a divisional application, there must has to be plurality
of invention. Meaning there by the specification of the parent application must
contains multiple inventions. Only in that case divisional application can succeed.
The Hon'ble High court of Delhi in the present case observed
that divisional application for Patent can not succeed as in the parent
application only original 'DPP IV inhibitor' arising out of a Markush formula,
in various permutations and combinations describing its use and method for
treatment were disclosed, which can not be said to be plurality of invention.
Hence it can be said that for divisional application to
succeed, the first criteria is that the amendment should only be by way of
correction, disclaimer , incorporation of facts. The second criteria is that
the divisional application should not contain any claims which were not
disclosed in the Parent application. And the last one is that specification of
the parent application must qualify for the test of plurality of invention
disclosed in it. If a divisional Patent Application qualify for all these
tests, it may qualify to be allowed.
