The Indian Patent Office released the final CRI Guidelines 2025 on July 29, 2025, fundamentally reshaping how computer-related inventions are examined under Section 3(k) of the Patents Act. The guidelines introduce a four-limb framework for mathematical methods, business methods, algorithms, and computer programmes per se, with detailed step-by-step assessment procedures and 73 pages of illustrative examples. For tech founders and patent strategists, the key takeaways are the heightened disclosure requirements for AI and blockchain inventions, the absolute bar on business method patents, and the critical importance of demonstrating technical effect beyond mere software implementation.
