This appeal originated from a decision by the patent authority rejecting a patent application for optimizing mobile terminal operations on the grounds that it was non-patentable under rules covering software, mental acts, and schemes. While the court had previously sent the application back to the patent authority for a fresh look, it kept the legal matter open because there were no official guidelines on how to evaluate patent objections concerning pure schemes, rules, or mental acts. Recognizing the public importance, the court engaged an independent legal expert to help formulate a standardized framework. The legal reasoning noted that the law intends to exclude purely abstract processes—such as simple mental calculations or game rules—that take place solely within the mind without tangible physical implementation. However, if an invention involves physical hardware interacting with software, requires tangible components, or produces a physical effect, it should not be dismissed as a mere mental act. The court laid down a clear seven-step guideline for patent examiners to properly test such claims going forward and closed the proceedings after directing that these guidelines be submitted to the Patent Office.

Analytical Article on Judgment
Introduction:
The legal framework governing patents in India strikes a delicate balance between encouraging technological innovation and preventing monopolies over abstract concepts or basic human thought processes. Under the Patents Act, 1970, statutory exclusions under Section 3 strictly define what does not constitute an invention. In this judgment, the High Court addresses a long-standing regulatory vacuum regarding the interpretation and practical evaluation of objections under Section 3(m) of the Act. By framing definitive examination guidelines, the Court provides clarity for both patent applicants and examiners on distinguishing abstract mental acts from patentable technical processes.
Factual and Procedural Background:
The dispute traces back to Patent Application No. 468/DELNP/2008, titled "Method and Arrangement for optimising the Operational Times and Cell Change Performance of Mobile Terminals," filed by the appellant company. On December 29, 2016, the patent authority issued an order refusing the application under Section 3(k) (computer programs per se or algorithms) and Section 3(m) (mere scheme, rule, or method of performing mental act) of the Patents Act, 1970.
The applicant challenged this refusal through an appeal. Upon hearing the parties on the merits, the Court, via an order dated February 26, 2026, remanded the application back to the patent office for de novo consideration. However, during the proceedings, it became apparent that the Patent Office lacked standard guidelines for evaluating Section 3(m) objections. Consequently, the Court retained the appeal for a limited public-interest purpose to establish formal principles, appointing an Amicus Curiae to assist in drafting comprehensive guidelines. After perusing the draft submissions and an updated report submitted on May 20, 2026, the Court finalized its directions on August 4, 2026.
Dispute Before the Court
The core legal question before the Court was to define the precise legal scope of Section 3(m) of the Patents Act, 1970, and establish an objective test for evaluating objections raised under it.
The main tension revolved around how patent examiners assess process claims involving analytical, computational, or logic-driven steps. While the statutory exception prohibits granting monopolies over "mere schemes, rules, or methods of performing mental acts," applicants argued that claims incorporating software and hardware working in unison to deliver physical outcomes were being improperly rejected as mere abstract thoughts or mental exercises. The Court needed to resolve how to prevent overbroad rejections while ensuring pure abstractions remain excluded from patentability.
Reasoning and Analysis of the Court
The Court traced the historical legislative intent behind Section 3, noting that while the Indian Patents Act, 1911 contained no such provision, Clause 3 of the Patents Bill, 1953, and subsequent revisions by the Justice Ayyangar Committee codified explicit exceptions to prevent inappropriate monopolies in the interest of the public and national economy. Section 3(m) was added by an amendment in 2002 to align Indian law with international standard practices, mirroring Article 52(2)(c) of the European Patent Convention (EPC).
Analyzing the text of Section 3(m)—which excludes "a mere scheme or rule or method of performing mental act or method of playing game"—the Court highlighted that the qualifier "mere" governs the first three exceptions. This means the exclusion applies strictly to claims that amount solely to a mental act and nothing more. A "mental act" refers to cognitive functions such as calculating, reasoning, evaluating, or exercising judgment.
The Court emphasized three foundational principles:
- Independent Evaluation: Section 3(m) acts as an independent bar and must not be conflated with tests for novelty or inventive step under Section 2(1)(j) or 2(1)(ja).
- Whole-Claim Construction: Claims must be assessed as a whole without dissecting them into isolated steps. If a process claim incorporates physical means or hardware interactions, the presence of an analytical step does not automatically render the entire claim a mental act.
- Pari Materia and Precedents: Drawing support from European Patent Office (EPO) Board of Appeal decisions (T 914/02 General Electric, T 619/02 Quest International, and T 471/05 Philips), the Court observed that exclusions apply to purely abstract, conceptual implementations lacking non-abstract, physical activities. Domestic precedents were reaffirmed, including Koninklijke Philips N.V. v. Maj (retd) Sukesh Behl & Anr. (holding physical processes producing tangible output fall outside Section 3(m)), Lava International Ltd. v. Telefonaktiebolaget LM Ericsson (holding hardware-software interactions for mobile signaling are not mere mental acts), and Novartis v. UOI (on distinguishing statutory eligibility from novelty).
To institutionalize these principles, the Court set forth seven examination steps:
- Step 1 (Claim Construction): Construe the claim as a whole as understood by a person skilled in the art.
- Step 2 (Product Claims): Genuine product or device claims defined by physical features are not hit by Section 3(m).
- Step 3 (Monopoly Scope): Identify the monopoly of process claims as a whole rather than isolating individual mental steps.
- Step 4 (Applying Exclusion): Test whether the monopoly can be infringed by someone doing nothing but thinking/calculating. Section 3(m) is not attracted if the claim recites integral physical means, requires hardware-software interaction, or yields a tangible output.
- Step 5 (Token Additions): Mere nominal or post-solution physical steps (e.g., printing or displaying results) will not save an otherwise purely mental claim.
- Step 6 (No Conflation): Do not conflate eligibility under Section 3(m) with obviousness or novelty.
- Step 7 (Separation from 3(k)): Computer-implemented methods should be examined under Section 3(k), not rejected under Section 3(m).
Final Decision of the Court
The Court directed that the formulated examination guidelines be placed before the Controller General of Patents, Designs and Trademarks for implementation within six weeks. Having completed the formulation of these guidelines in the public interest—the substantive appeal having already been remanded in an earlier order—the proceedings were formally closed.
Point of Law Settled
This judgment establishes clear, structured guidelines defining the scope of Section 3(m) of the Patents Act, 1970. It settles that Section 3(m) applies exclusively to pure mental acts, schemes, or logic exercises carried out solely in the mind. Incorporating physical hardware, interactive system components, or steps producing a tangible output removes a process from the purview of Section 3(m). Furthermore, it settles that patent examiners must evaluate claims as a whole, refrain from treating computer-implemented claims under Section 3(m) instead of Section 3(k), and strictly avoid conflating subject-matter patentability with novelty or inventive step.
