While the Patentability search is a comprehensive search for measuring the Patentability criteria, the knockout search is a quick search on patentability. It may include few references which may pose a problem or a conflict with the Patent application and its prosecution. This search, as it is non-comprehensive, is faster as compared to Patentability search. TSR does this search for the clients who are interested in just superficially requiring the patentability of their invention.
