Delhi High Court Rules Algorithm-Based Inventions Not Patentable Under Indian Law
Court says embedding algorithms in hardware does not make them patent-eligible
Ruling reinforces India’s strict stance on software patents without technical innovation
By Our Legal Reporter
New Delhi: November 08, 2025:
In a landmark judgment, the Delhi High Court reaffirmed that algorithm-based inventions and computer programs without technical advancement are not patentable in India. The ruling came in response to an appeal filed by Kroll Information Assurance LLC, challenging the refusal of its patent application by the Controller General of Patents, Designs and Trademarks.

The Court’s decision is expected to have a significant impact on India’s intellectual property landscape, particularly in the technology sector, where software-driven innovations often seek patent protection.
Background of the Case
Kroll Information Assurance LLC had filed a patent for a system and method designed to identify sensitive information shared over peer-to-peer networks. The invention relied primarily on algorithms executed by computers.

The Controller General rejected the application, stating that the invention lacked technical advancement and was essentially an algorithm implemented through a computer program. Kroll argued that embedding the algorithm in hardware should make it patentable—but the Court disagreed.
Court’s Key Observations
- Algorithms and Computer Programs Are Not Patentable: Under Section 3(k) of the Patents Act, algorithms and computer programs per se are excluded from patent protection.
- No Technical Effect: The invention showed no technical advancement or tangible technical effect beyond routine computer processing.
- Embedding in Hardware Does Not Help: Simply embedding an algorithm into hardware does not make it patent-eligible.
- Consistency With Global Standards: The decision aligns with international norms that grant software patents only if a technical contribution is shown.
Why This Matters
- For Tech Companies: Sets clear boundaries on software patent eligibility.
- For Startups: Promotes genuine technical innovation instead of abstract ideas.
- For Courts & Regulators: Reinforces consistent interpretation of Section 3(k).
- For Investors: Brings clarity on IP rights in India’s IT sector.

- Judicial Precedents: Courts have held that software must demonstrate a technical effect to qualify for patents.
- Global Perspective: India’s stricter stance aligns with preventing monopolization of abstract ideas.
Expert Reactions
Legal experts welcomed the ruling, saying it provides long-needed clarity for innovators and applicants. Technology analysts noted it encourages companies to pursue genuine technical innovation rather than abstract software ideas.
Broader Implications
- Innovation Focus: Companies must demonstrate technical contributions in their inventions.
- Patent Strategy: Applicants need to highlight tangible technical effects.

- Global Competitiveness: May influence multinational IP strategies in India.
Conclusion
The Delhi High Court’s ruling marks a milestone in Indian patent law. By upholding the exclusion under Section 3(k), the Court ensures patents remain reserved for genuine technical advancements rather than abstract algorithmic ideas. This judgment is set to guide future innovations and patent strategies across India’s technology ecosystem.
