Patent ID: 7854671

Claim:
A sports ball comprising: at least six identical 4-sided polygonal panels, each said panel having 4 curved edges and 4 vertices, each said edge being bound by two said vertices, wherein said curved edges are either convex or concave and arranged such that each said convex edge alternates with each said concave edge, wherein said curved edges are arranged cyclically around said vertices such that said concave edge of one said polygonal panel mates with said concave edge of adjacent said polygonal panel, and wherein said curved edges are asymmetric, said asymmetry of said curved edge enabling a more uniform width of said 4-sided polygonal panel; the ball further comprising an outer layer and an inner layer, said inner layer is the topological dual of said outer layer and oriented so that the vertices of said outer layer overlay the panels of said inner layer, and said polygonal panels of said outer layer overlay the vertices of said inner layer.
