Old Wine in New Bottle: Distillery Waste Patent Denied

Two bottles are placed side by side against a muted background. The bottle on the left is labeled "DISTILLERY WASTE" and contains a dark liquid, while the bottle on the right is labeled "PATENT DENIED" and also contains a similar dark liquid.

Delhi HC affirms rejection of a patent on ZLD process from distillery waste, citing lack of inventive step and application of Section 3(d) of the Patents Act.
