Delhi High Court ne Japanese firm Hirotsu Bio Science Inc. ki patent application ko reject karne ka faisla sunaya hai, jo August 2023 ke patent office ke order ko uphold karta hai. Company "in vitro method for detecting cancer" ke liye exclusive rights chahti thi, jismein Caenorhabditis elegans naamak nematode ka behavior use kiya jata hai, jo urine jaise samples mein cancer-specific odors se attract hote hain.
Justice Tejas Karia ne Indian Patents Act ke Section 3(i) par zor diya, jo diseases ke liye diagnostic methods ko patentable hone se rokta hai. Court ka kehna tha ki yeh process cancer ke liye ek general diagnostic method hai, na ki sirf preliminary screening tool jaisa company argue kar rahi thi.
Firm ne argue kiya tha ki unki technique human body ke bahar kaam karti hai aur ismein clinical judgment involve nahi hai, isliye yeh non-patentable medical diagnoses se alag hai. Lekin, court ne yeh distinction dismiss kar diya, kaha ki yeh matter nahi karta ki method kaun perform karta hai. Decision ne medical diagnostic procedures ki patentability par India ke stance ko reinforce kiya hai aur future mein aise applications ke liye precedent set kiya hai. Hirotsu Bio Science ki taraf se advocates Kshitij Saxena, Saransh Vijayvargiya, aur Daksh Oberoi ne represent kiya, jabki Assistant Controller of Patents and Designs ke liye advocates Manisha Agarwal aur Nipun Jain present the.
