PART I : Proposed Amendments

  1. Definitions:

(3) Claim construction brief

Existing Provision:

(3) Claim construction brief :- A brief which would enumerate all the claims relied upon, break down the construction of each of the terms contained in the claims, their meaning thereof, as also the overall scope and effect of all the claims relied upon, as per the party filing the brief.

Proposed Provision

(3) Claim construction brief :- A brief which would enumerate all the claims relied upon, identify the elements of each of the claims and construe the meaning of terms used to define each of the elements in order to determine the scope and effect of each of the claims relied upon as per the party filing the brief.

Reason for the proposed change

Based on case law and established patent practice, claim construction is done by identifying the elements or steps in a claim and constructing each element in order to understand the metes and bounds of the claim. The definition has been modified to bring it in consonance with the aforestated understanding.

(4) Invalidity Brief

Existing Provision:

(4) Invalidity brief:-
i) Invalidity brief shall contain the precise prior art with its date, country of origin, reference number and the specific portion of the prior art which anticipates or renders the claim obvious.
ii) If the Defendant relies on prior publication/prior use of the patented product/process, the brief shall be specifically referenced along with the date, title of publication, country of origin, and or the source of the product / process to show use including reference to any inspection reports.
iii) Invalidity brief shall contain a conclusion on how each item of the prior art and/or combination thereof renders the patent invalid, due to lack of novelty/inventive step. If lack of inventive step is pleaded, the brief shall clearly explain how the invention would have been obvious to the notional person skilled in the art, who did not have the benefit of the invention, to combine the teachings of the prior art and arrive at the invention.
iv) If invalidity is pleaded on any of the grounds contained in Section 3 as being non-patentable, an explanation for the same along with scientific reasoning and case law relied upon shall be mentioned.

Proposed Provision:

(4) Invalidity Brief:-
i) Invalidity brief shall contain the relevant prior art references with details such as its date, country of origin, reference number and the specific portion of the prior art which anticipates or renders the claim obvious.
ii) If the Defendant relies on prior publication/prior use of the patented product/process, the brief shall be specifically referenced along with the date, title of publication, country of origin, and or the source of the product / process to show use including reference to any inspection reports.
iii) Invalidity brief shall contain a conclusion on how each item of the prior art and/or combination thereof renders the patent invalid, due to lack of novelty/inventive step. If lack of inventive step is pleaded, the brief shall clearly explain, the lack of technical advancement and/or economic significance and how the invention would have been obvious to the person skilled in the art, as of the priority date, to combine the teachings of the prior art and arrive at the invention.
iv) If invalidity is pleaded on any of the grounds contained in Sections 3 and 4 as being non-patentable, an explanation for the same along with scientific and legal reasoning shall be mentioned.
v) If the invalidity is pleaded based on any grounds contained in section 64(h) and/or section 64(i), the brief shall clearly point out the claims that have not been sufficiently disclosed in, supported by or enabled in the specification with an explanation of the insufficiency for each of the claims.

Reason for the proposed change

i) Prior knowledge and prior use also form part of prior art for invalidity purposes, and the definition has been modified as it does not cover them expressly.
ii) This provision has not been amended.
iii) The definition of inventive step in the Patents Act includes technical advancement and economic significance, which do not form part of the existing definition. The terms have been introduced to the definition. Furthermore, inventive step as of the priority date has been specifically mentioned in the proposed definition.
iv) As Section 4 also deals with non-patentable inventions, it has been added to the definition.
v) Important grounds of invalidity such as insufficiency of disclosure and enablement have not been mentioned in the existing definition, and the same have been added to it.

Reason for the proposed change:
