In a recent case[1], Novartis AG[2] v. Natco Pharma Ltd.[3], the Division Bench (DB) of the Delhi High Court (DHC) adjudicated on the extent of engagement a pre-grant opponent should be allowed under the Patents Act, 1970, in the course of proceedings initiated by the Controller, requiring the patent applicant to amend or modify the patent application.
Novartis AG had filed a patent application before the Controller of patent. Subsequently, the application was published for inviting pre-grant oppositions. Various oppositions were filed against the application, including one by Natco Pharma Ltd. Hearing on all Pre-Grant Oppositions were concluded on November 3, 2022. The Controller asked Novartis to carry out amendments in the patent application and issued a notice dated November 25, 2022, to the effect. In the hearing, Novartis agreed to revise claim 4 and reword claim 5. Novartis submitted amended claims on December 5, 2022, and consequently the patent came to be granted on December 14, 2022, as IN4145184.
Thereafter, Natco Pharma Limited filed a writ petition against the order of the Controller of Patents, dated December 14, 2022, and argued that the amendments in IN4145184 filed by Novartis were made and allowed without Natco being afforded an opportunity of hearing. The submissions advanced by Natco, in the said writ petition were essentially that a pre-grant opponent would have the right to represent against both voluntary amendments as well as those that may be directed by the Controller. Natco also argued that the consideration of the application, alongside the representations of opposition are not liable to be viewed as operating in separate silos. The opposition and examination proceedings, according to Natco, clearly merge, thus obligating the Controller to place all pre-grant opponents on notice of any amendments that may be directed by it. Natco’s submissions were accepted by the learned Single Judge, leading to the institution of the present appeal.
The DB allowed the appeal and set aside the impugned judgment. The DB held that the Controller, as per Section 13[4], has the jurisdiction to independently require an amendment to be made in the application, the specification or any other document filed, post an independent evaluation of the application by virtue of Section 15[5] of the Act. The DB further held that the rejection of an opposition does not inevitably result in a patent application being granted. The DB was, therefore, of the opinion that, the Controller must be independently satisfied that the application merits acceptance. This independence is vital to uphold the credibility of the patent system, ensuring that decisions are made impartially, based on the merits of the application rather than external and interested influences. The DB, therefore, held that, both the Act as well as the Rules clearly envisage a dichotomy between the examination process and opposition process. The Controller may consider any opposition that has been filed during examination, but it would be incorrect to say that this warrants the opponent being accorded participation in the examination process.
The main findings of the decision are:
- The Controller must statutorily conduct an examination process, irrespective of any opposition being filed.
- The objections/ oppositions aid the Controller in taking a holistic view in consideration of a patent application.
- The objective of the pre grant opposition process is to provide a platform to “any person” to express objections regarding a patent application. The opposition cannot solely determine whether a patent is liable to be granted. The Controller is bound to consider other factors in accordance with the Act, too.
- The examination process serves a wider purpose and involves in depth assessment of the patent application. During examination, a thorough and independent evaluation of the application is carried out by the examiner and the Controller. Thus, the two processes, examination and opposition, are distinct from each other and this difference is necessary for achieving the underlying objectives of each process.
- On a conjoint reading of Rule 55[6](3), (4) and (5), it can be concluded that hearing under Rule 55 is limited to representation alone.
- The sub-Rule 55(3) provides discretionary power to the Controller. Once the Controller is satisfied that the representation filed by an opponent raises questions worthy of consideration, it would proceed to place the applicant on notice, enabling it to file its statement and evidence. Thus, the process of hearing in respect of an opposition begins only when opposition warrants rejection or amendment of the application.
- A mere filing of a representation would not prompt issuance of notice under Rule 55(4).
- Right of hearing that is contemplated in Rule 55(5) is one which is concerned solely with the adjudication and disposal of the representation for opposition. The opponent cannot be said to have a right of hearing in the examination process.
- Voluntary amendment by the Applicant and amendment pursuant to a direction of the Controller are two distinct concepts under the Act. The hearing and adjudicatory process under Section 57[7] (4) are limited to voluntary amendments by the Applicant and do not apply to amendments pursuant to the direction of the Controller.
