https://www.taxtmi.com/caselaws?id=175209 Indian patent law required a claimed invention to be new, useful, and more than a routine workshop improvement. Prior public knowledge and prior use negatived novelty, and inventive step had to be assessed objectively from the standpoint of a skilled worker in the field. On the facts discussed, the specification and claims disclosed only an old lathe-based arrangement with minor variations in the pressure spindle, adapter, and bracket, while similar lathes, tailstocks, adapters, and utensil-turning methods were already known before the patent date. Utility alone could not sustain protection where novelty and inventive step were absent, so the patent was treated as invalid and liable to revocation. en-us Wed, 13 Dec 1978 00:00:00 +0530 Sat, 14 Nov 2015 11:21:22 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=175209 Indian patent law required a claimed invention to be new, useful, and more than a routine workshop improvement.
