The Bombay High Court has reaffirmed that patent applications cannot be rejected through mechanical, non-speaking orders that fail to articulate reasoning or address submissions. This judgment establishes a critical procedural safeguard for applicants under the Patents Act, 1970, ensuring that refusal orders are transparent, reasoned, and grounded in fair hearing principles.
Background & Facts
The Dispute
The petitioner, Medipack Global Ventures Private Limited, filed Patent Application No. 202221047021 titled "A Syringe With Breakable Plunger" on 18th August 2022. The invention relates to a single-use safety syringe designed to prevent reuse by incorporating a breakable plunger mechanism that locks and fractures after injection, thereby reducing risks of infection transmission from needle reuse.
Key Facts
- The invention comprises: (i) a barrel with inner tear-off notches; (ii) a plunger with a base, head, and frangible section between them, featuring outer locking grooves; and (iii) a spacer that prevents full insertion of the plunger until removed after filling.
- The plunger breaks at a designated frangible point when the locking grooves engage the barrel’s notches, rendering the syringe unusable.
- The base of the plunger is oblong-shaped with a flange extending outward, acting as a lever to snap the plunger after use.
- The application was published on 18th November 2022 in Journal No. 46/2022.
- A First Examination Report (FER) dated 24th November 2022 raised objections under Sections 2(1)(j) (novelty) and 2(1)(ja) (inventive step), as well as Sections 10(4)(c) and 10(5) for lack of clarity.
- The petitioner submitted detailed amendments and a comparative table distinguishing its claims from prior art documents D1 (US2004039334A1) and D2 (US2014155826A1) on 11th December 2022.
- A hearing notice dated 20th October 2023 scheduled a hearing for 16th November 2023, but limited objections solely to inventive step under Section 2(1)(ja). No novelty objection was mentioned.
- On 30th November 2023, the petitioner filed written submissions with further amended claims and detailed feature-by-feature analysis against prior art.
- The impugned order dated 4th March 2024 rejected the application on grounds of both novelty and inventive step.

The Parties' Positions
Petitioner: Argued that the Controller violated natural justice by introducing a novelty objection not raised in the hearing notice, and that the order was non-speaking, lacking independent analysis of claims or engagement with petitioner’s detailed submissions.
Respondent: Contended that the order was comprehensive and that the Controller had considered all submissions, though unable to point to specific reasoning in the order when challenged.
Relief Sought
The petitioner sought quashing of the impugned order dated 4th March 2024, and remand of the application for fresh adjudication by a different Controller, with all rights and contentions kept open.
The Legal Issue
Can a patent application be refused on a ground of novelty not raised in the hearing notice, and can such refusal be sustained through an order that merely reproduces prior art and applicant’s claims without providing independent reasoning?
Arguments Presented
For the Petitioner
Mr. Hiren Kamod submitted that the Controller violated the principles of natural justice by introducing a novelty objection under Section 2(1)(j) in the impugned order, despite the hearing notice of 20th October 2023 limiting objections exclusively to inventive step. The petitioner had no opportunity to address novelty, rendering the proceeding unfair. He further argued that the order was non-speaking: it reproduced verbatim extracts from prior art and the petitioner’s claims without mapping features, explaining anticipation, or justifying obviousness. He relied on Huhtamaki OYJ v. Controller of Patents and Biomoneta Research Pvt. Ltd. v. Controller General of Patents to demonstrate that boilerplate language and mechanical copying are legally insufficient. He emphasized that the Patent Office Manual mandates holistic assessment of the invention and prohibits mere mosaicing of prior art elements.
For the Respondent
Mr. Ashish Mehta contended that the order must be read as a whole and that the Controller had implicitly considered all submissions. He asserted that the rejection was based on thorough examination and that the reasoning was inherent in the order. However, when pressed to identify specific analysis in the order, he could not point to any independent reasoning or mapping of claim elements to prior art.
The Court's Analysis
The Court conducted a rigorous review of the impugned order and found it fundamentally defective on three grounds. First, the Controller introduced a novelty objection in the final order that was never raised in the hearing notice. This deprived the petitioner of a fair opportunity to respond, violating the cardinal principle of audi alteram partem. The Court held that procedural fairness in patent prosecution is non-negotiable, particularly when the outcome affects a 20-year monopoly.
"The Controller has therefore rejected the Petitioner's Application on a ground which was not raised in the hearing notice and therefore one to which the Petitioner did not have the opportunity to respond."
Second, the order was devoid of any independent reasoning. It merely copied paragraphs from prior art documents and the petitioner’s claims, concluding with generic phrases such as "not persuasive" and "well disclosed" without explaining how the claimed invention was anticipated or rendered obvious. The Court noted that such mechanical reproduction constitutes a failure of application of mind and is inconsistent with the statutory requirement under Section 117A that orders be reasoned.
"There is absolutely no reasoning and/or explanation as to how the Petitioner’s amended claims were anticipated or rendered obvious from the prior art cited."
Third, the Court emphasized that the Patent Office Manual requires a structured, holistic assessment of inventive step, prohibiting the mere aggregation of known elements. The Controller failed to identify distinguishing features, assess whether they were suggested in prior art, or explain why a person skilled in the art would be motivated to combine the references. The Court cited Huhtamaki to reinforce that non-speaking orders are an "endemic problem" and reiterated the Delhi High Court’s directions mandating systematic, sequential reasoning for every objection.
The Court also rejected the respondent’s argument that reasoning was implicit, holding that legal conclusions must be explicit, especially in appealable orders. The absence of reasoning not only violates natural justice but also renders appellate review impossible.
The Verdict
The impugned order dated 4th March 2024 is set aside. The matter is remanded to the Patent Office for fresh consideration before a different Controller. All rights and contentions of the parties are kept open. No costs are awarded. The Controller shall adjudicate the application in accordance with law, ensuring full compliance with the Patent Office Manual and the requirement for reasoned, speaking orders.
What This Means For Similar Cases
Non-Speaking Orders Are Per Se Invalid
- Practitioners must challenge any patent refusal order that lacks mapping of claim elements to prior art, or that uses boilerplate phrases like "not persuasive" or "carefully considered but not accepted."
- Such orders are voidable under Section 117A and must be set aside without needing to prove substantive error.
- Always request a copy of the Patent Office Manual and cite Chapter 4 on Inventive Step in submissions.
Hearing Notices Define the Scope of Adjudication
- Any ground introduced in the final order not mentioned in the hearing notice is procedurally invalid.
- Applicants must immediately object if new grounds appear in the refusal order and seek remand on grounds of natural justice.
- The hearing notice is not a mere formality - it is the procedural boundary within which the Controller must operate.
Holistic Assessment Is Mandatory for Inventive Step
- The Controller cannot rely on mosaicing of prior art elements; each claim must be assessed as a whole.
- Applicants should submit feature-by-feature comparison tables in responses to FERs and hearings.
- Courts will not uphold rejections based on conclusory statements; reasoning must demonstrate why a skilled person would combine references.
