One of the challenges surrounding patent law revolves around the locus of a
pre-grant patent opponent in the patent examination process. This article delves
into the critical examination of the order dated 14.12.2022, which allowed
certain amendments in the Indian Patent Application No. IN4145, and subsequently
led to litigation.
The crux of the controversy lies in the alleged violation of the principles of
natural justice. The opponent contended that the order permitting amendments to
the patent application was issued without granting them a fair hearing.
Specifically, all five pre-grant opposition hearings had concluded on 03
November 2022. Despite this, the Controller of Patents directed the applicant to
carry out amendments, which were eventually allowed on 14.12.2022.
The Core Legal Question:
The pivotal issue at hand is whether an opponent possesses the right to
participate in the patent examination process, especially when amendments are
under consideration. Stated differently, does the opponent have a stake in the
examination process, mandating their participation when modifications to the
patent application are being evaluated?
The Hon'ble Division Bench's ruling provided a nuanced interpretation of the
relevant legal provisions. According to Rule 55(5), the right of hearing is
primarily associated with the adjudication and disposal of the representation
for opposition. The court opined that conferring an opportunity for a hearing at
the representation stage does not automatically translate to an inherent right
for the opponent to participate in Patent examination process.
Furthermore, the court elucidated that while pre-grant opposition undoubtedly
aids the Controller in decision-making, it does not ipso facto grant opponents
an inherent right to participation or an audience during the Patent examination
process. This interpretation upholds the procedural autonomy of the Controller
in conducting examinations while balancing the interests of both applicants and
The Division Bench's interpretation provides clarity on the locus of a pre-grant
patent opponent within the patent examination framework. By distinguishing
between the stages where opponents have a right to be heard, such as during
pre-grant opposition, and stages where their participation is not mandated, the
court ensures a balanced and efficient patent examination process.
The Concluding Note:
In conclusion, the Hon'ble Division Bench's analytical approach reaffirms the
statutory framework's intent, emphasizing the distinct stages of the patent
examination process and the corresponding rights of pre grant opponents.
