Cracking Open the Atom: How the SHANTI Act Rewrites Section 4 of the Patents Act, 1970

The Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India Act, 2025 (SHANTI Act) fundamentally transforms India's nuclear patent landscape from categorical prohibition to conditional authorization.

​The Legacy Framework (Section 20(1) of the Atomic Energy Act, 1962)

For over five decades, Section 20(1) imposed an across-the-board prohibition on patents for inventions in the atomic energy field. This encompassed reactor technologies, uranium enrichment processes, radioactive substance handling, and nuclear safety infrastructure. The Central Government retained sweeping discretionary authority to withhold patent protection across the entire nuclear sector.

​The New Framework (Section 38 of the SHANTI Act)

The SHANTI Act introduces a permissive-with-exceptions model for nuclear energy patents. Patents may be granted for nuclear-related inventions, provided they satisfy two conditions: they must be intended for peaceful purposes and must not fall into two statutorily prohibited categories:

Government-Reserved Activities: Uranium enrichment or isotopic separation, management of spent nuclear fuel including reprocessing and radionuclide separation, handling of high-level radioactive waste, production and isotopic upgrading of heavy water, and any additional activities subsequently notified by the Central Government

Security-Sensitive Inventions: Inventions that the Central Government determines to be sensitive in nature or to carry implications for national security

Critical Requirements

• Advance Notification Requirement: Inventors must communicate the nature and substance of nuclear-related inventions to the Central Government prior to any disclosure to external parties

• Compulsory Government Review: Applications raising questions about reserved activities or security sensitivity are automatically forwarded to the Central Government for direction

• Executive Oversight Authority: The government retains the right to examine pending applications and issue orders directing the Controller to deny protection where applications fail to meet Section 38 criteria

Commercial Opportunity

The amended framework creates patent eligibility for a range of civilian nuclear technologies: next-generation reactor systems, diagnostic radiation equipment, therapeutic nuclear medicine applications, solutions for radioactive waste remediation, nuclear facility decommissioning technologies, nuclear safety monitoring instrumentation, advanced imaging diagnostics, and industrial radiation utilization.

Strategic Implications

The SHANTI Act shifts from blanket exclusion to conditional inclusion. Private sector players can now seek patent protection for nuclear technology innovations. Success requires embedding regulatory compliance into research from the start and maintaining ongoing dialogue with the Department of Atomic Energy about technology characterization and security classification.
