Bombay High Court quashes unreasoned patent rejection in Huntington Alloys case

In a landmark ruling delivered on April 7, 2026, the Hon’ble Bombay High Court (Bench comprising Coram of Justice Bharati Dangre & Justice Manjusha Deshpande) reinforced a fundamental principle of administrative law, i.e., the power to refuse a patent is not a power to be silent.

The case, Huntington Alloys Corporation v. Union of India & Ors. (Writ Petition No. 2086 of 2021), serves as a vital reminder that even when national security or “atomic energy” is invoked, the state cannot bypass the requirement of a reasoned order.

Background

The Petitioner, a US-based corporation, filed a PCT national phase patent application in November 2010 in India for an “Ultra Supercritical Boiler Header Alloy and Method of Preparation.” The invention was metallurgical in nature, designed for a high-strength, high-temperature nickel-cobalt-chromium alloy for application in Ultra Supercritical Boiler applications capable of long-life service at 538°C to 816°C. The alloy is uniquely suitable for the header pipe, offering a combination of strength, ductility, toughness, and fissure-free weldability, which is critical for joining boiler tubes to the header.

A request for Examination was filed as early as 2012, but no steps were taken by the Authority under Sections 12 to 14 of the Act of 1970, which deal with the Examination of the application, the search for anticipation by previous publication and prior claim, and the consideration of the report of the examiner by the Controller. In 2020, the Patent Office referred the matter to the Department of Atomic Energy (DAE) under Section 20(6) of the Atomic Energy Act. The learned Controller filed an affidavit, submitting that as the invention of the Petitioner consists of Niobium and Tantalum compositions, it was appropriate to obtain necessary directions from the DAE. The DAE issued a short, one-paragraph direction, stating simply that the invention related to atomic energy and directing that the patent must be refused under Section 4 of the Patents Act, 1970.

The legal tug-of-war

The Union of India argued that under Section 20 of the Atomic Energy Act, 1962, the DAE is the final and absolute authority. They contended that since the alloy contained elements like Niobium and Tantalum, it fell within the DAE’s purview. Their core argument was that once the DAE issues a direction, the Patent Office has no scope to grant a hearing or provide further explanation.

Interestingly, Niobium and Tantalum are transition metals generally found together in nature owing to their similar physical and chemical properties. Hardness, conductivity, and resistance to corrosion are inherent properties of these metals. Niobium is mainly used in the production of high-strength steel alloys that are used in pipelines, transportation infrastructure, and structural applications. At the same time, Tantalum finds its prominent use in electronic capacitors that can be used in cell phones, computer hard drives, and implantable medical devices like pacemakers and neurostimulators, automotive electronic control units (ECUs) and infotainment systems, and aerospace and military avionics, where performance and durability are critical.

The Petitioner, however, argued that a metallurgical alloy for a boiler is not “atomic energy” (which refers to energy released from atomic nuclei via fission or fusion). They highlighted that by failing to provide technical reasons, the DAE effectively stripped the Petitioner of their statutory right to amend the application, a remedy specifically provided under Section 65(2) of the Patents Act, which allows an applicant to vary their specification to avoid prohibited categories.

Key takeaways from the judgment

1. Reasons are the “heartbeat” of a decision

The Court used powerful imagery, describing a reasoned order as the “heartbeat” of a judicial or administrative decision. It held that:

“The reasons of a decision are considered to be its ‘heartbeat’, replacing subjectivity with objectivity… A non-speaking or unreasoned order hinders the Appellate Court’s ability to test correctness.” The Court emphasized that the authority must disclose its mind to ensure transparency and accountability, especially when a property right like a patent is being denied.

2. The right to amend is sacrosanct

The Court highlighted that the law doesn’t just allow for rejection; it allows for correction. Under Section 65(2), an applicant is permitted to amend their complete specification in a manner that might save the invention from the “atomic energy” embargo. Without knowing the specific technical basis of the DAE’s objection, an applicant is denied the opportunity to vary their invention to satisfy the law.

3. Technological evolution

The Court touched upon the “Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India Act, 2025.” This modern statute recognizes India’s self-reliant capability in nuclear research and signals a shift toward encouraging inventions that use nuclear energy for welfare and peaceful purposes. This evolution suggests that the old “blanket ban” or “black-box” approach to rejections requires far more transparency in the current technological era.

Conclusion

The Bombay High Court has set aside the rejection and directed the DAE and Patent Office to reconsider the application. The mandate is clear: if you refuse a patent, you must provide the technical and legal logic for that refusal. For the IP community, this judgment is a critical safeguard against arbitrary decision-making. It ensures that inventors are treated as partners in innovation, rather than obstacles to national policy, and that the “atomic energy” exception is not used to shield unreasoned administrative actions.
