Delhi HC Addresses Confusion in Patentability
In a significant ruling, the Delhi High Court sought to clarify the ambiguous provisions of Section 3(k) of the Indian Patents Act during the recent case of Blackberry v. Controller. This subsection has become a contentious point in Indian patent law, primarily focusing on the patentability of mathematical methods and algorithms.
The court noted that despite multiple iterations of the CRI Guidelines, which were released in July 2025, the language of Section 3(k) continues to create uncertainty. The judges emphasized the need for a clearer interpretation that aligns with the definitions provided in previous legal precedents.
“The ongoing confusion surrounding Section 3(k) necessitates a consistent approach to its interpretation,” the court stated.
This ruling holds important implications for patent practitioners as they navigate the complexities of Section 3(k). The need for consistent guidelines becomes increasingly critical for determining the eligibility of inventions, particularly in the rapidly evolving fields of technology and innovation.
