IPR Amicus: April 2025

Article

The Risdiplam saga: Delhi High Court adjudicates patent infringement suit between Roche and Natco By Vindhya S Mani, Harshita Agarwal and Surbhi Nautiyal

The first article in this issue of IPR Amicus discusses a recent decision of the Delhi High Court in a patent infringement suit between Roche and Natco. The authors believe that the decision, particularly the analysis of inventive step, may be wanting, especially in applying the concept of ‘bioisosterism’. They also note that despite evidence of enhanced efficacy, improved pharmacokinetic profile, and therapeutic advantages over known compounds, the Court appeared to have adopted a simplistic assessment of inventive step based on a simpliciter application of the bioisosterism concept. However, according to them, the order, while detailed and ostensibly rooted in public interest, raises concerns about the way the credible challenge test is applied, especially in aspects of substantive technical assessment concerning inventive step.

TNot all marks are created equal: The curious case of distinctiveness By Divya Vishvapriya and Kriti Sood

The second article in this issue of the newsletter discusses how the Courts are increasingly realizing that distinctiveness in trademarks may not necessarily be inherent, it can also be created via use. The article elaborately examines these changing interpretations, concentrating on significant rulings that have influenced India’s trademark protection laws. The authors discuss the different categories of distinctiveness and note that although descriptive and generic trademarks often encounter significant challenges, recent legal developments indicate a more business-oriented and practical perspective - considering composite marks that blend generic terms with unique stylization or design; evidence of acquired distinctiveness, such as consumer surveys, advertising expenditures; and brand recognition.
