In an important decision, Justice Senthilkumar Ramamoorthy, discussed Section 3(d) of the Patents Act, 1970.[1] The case involved a patent application no. 7096/CHENP/2015, which claimed priority from the US application number 61/815,502 dated 24 April 2013. The patent application claimed two polymorphic forms—A and B—of a compound RTA-408. Compound RTA-048 was claimed and granted in the Indian Patent Application No. 8486/DELNP/2014.[2] The patent application 7096/CHENP/2015 was refused essentially on the grounds of being not patentable under Section 3(d) of the Indian Patents Act.Continue Reading Court interprets “known substance” in respect of Section 3(d) of the Patents Act
