In Inox India vs Cryogas & LNG Express, Inox sued for copying proprietary engineering drawings and manufacturing descriptions. The Commercial Court dismissed under O VII R11 CPC, ruling drawings fell under the Designs Act, not the Copyright Act. Gujarat HC reversed, reinstating suit. SC examined whether drawings qualify as “artistic work” (Copyright Act s2(c)) or “design” (Designs Act s2(d)), noting s15(2) limits copyright for registrable designs after industrial reproduction. SC held mixed legal-factual issues require trial; O VII R11 improper. It directed Commercial Court to decide interim injunction within two months and complete trial within one year using a two-pronged nature-and-functionality test.
