Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A cricket bat comprising an elongated handle connected to an elongated blade along the longitudinal axes of said blade and handle to form a continuous elongated implement, said blade shaped to provide a front striking surface and a rear surface at the side opposed to the striking surface, characterised in that said rear surface is formed with at least one depression so configured that the thickness of said blade, in the region of its sweet spot, is greater than the maximum thickness of said blade at that part of the depression edge which is closest to the edge of said blade.
Claim 2
Dependent Claim
101 words
A cricket bat comprising an elongated handle connected to an elongated blade along the longitudinal axes of said blade and handle to form a continuous elongated implement, said blade shaped to provide a front striking surface and a rear surface at the side opposed to the striking surface, characterised in that said rear surface is formed with at least one depression so configured that the thickness of said blade, in the region of its sweet spot, is greater than the maximum thickness of said blade at that part of the depression edge which is closest to the edge of said blade.
Claim 3
Dependent Claim
36 words
A cricket bat as set forth in claim 1 characterised in that the thickness of said blade in the region of said sweet spot is greater than the thickness at any other part of the blade.
Claim 4
