Patentability of Software in United States and India: A Comparative Analysis

The growing centrality of software in modern systems, has intensified debates surrounding its patentability. Originally developed to safeguard tangible, industrial creations, patent law is now confronted with accommodating inventions rooted in algorithms, computational logic, and digital processes. This paper undertakes a comparative doctrinal analysis of software patentability in the United States and India, examining how each jurisdiction has navigated the tension between incentivising innovation and preventing the monopolisation of abstract ideas. In the United States, the evolution of judicial interpretation, particularly through the development of the two-step framework articulated in Alice Corp. v. CLS Bank International, reflects an attempt to recalibrate the boundaries of patent-eligible subject matter without legislative amendment. While software patents are not categorically excluded, their validity hinges on demonstrating an ‘inventive concept’ that transforms an abstract idea into a patent-eligible application. India, by contrast, adopts a legislatively anchored approach under Section 3(k) of the Patents Act, 1970, which excludes computer programs ‘per se’ from patentability. However, interpretive developments through Patent Office Guidelines and judicial decisions have introduced the concept of ‘technical effect’ or ‘technical contribution’ as a basis for limited protection of computer-related inventions. Through this comparative inquiry, the paper argues that software patentability reflects deeper regulatory philosophies: United States relies on judicial gatekeeping within an enabling statutory framework, whereas India employs statutory exclusion moderated by interpretive flexibility. The study highlights the implications of these approaches for innovation policy, legal certainty, and technological development in a rapidly evolving digital landscape.
