BISWANATH PRASAD RADHEY SHYAM vs HINDUSTAN METAL INDUSTRIES

The Supreme Court held that under the Patents Act, 1970, specifically Section 26(1)(f), a patent must demonstrate novelty and utility, and cannot merely be a verification of existing knowledge. The Court emphasized that an improvement must involve an inventive step and produce a new result to qualify for patentability. The patent granted to M/s. Hindustan Metal Industries was set aside as it did not meet these criteria, being merely a workshop improvement without novelty or inventive step.
