ITC Limited v.The Controller of Patents, Designs & Trademark

Calcutta High Court · 106547680

The Calcutta High Court ultimately ruled in favor of ITC Limited, emphasizing international IP principles (TRIPS and Paris Convention) which mandate that patentability cannot be denied merely because commercial exploitation is restricted by domestic law.
