Patent ID: 8216098

Claim:
A sports ball comprising: an outer layer and an inner layer, wherein said outer layer comprises at least two polygonal panels, each said polygonal panel having edges and vertices, each said edge being bound by two said vertices, each said polygonal panel meeting at least one more said panel at said vertex, and said inner layer comprises at least two polygonal panels, each said polygonal panel having edges and vertices, each said edge being bound by two said vertices, each said polygonal panel meeting at least one more said panel at said vertex, and wherein said inner layer is the topological dual of said outer layer and comprises the same number of said polygonal panels as the number of said vertices in said outer layer and further comprises the same number of said vertices as the number of said polygonal panels in said outer layer, and wherein said inner layer is oriented so that each of the vertices of said outer layer overlay exactly one of the panels of said inner layer, and each of said polygonal panels of said outer layer overlay exactly one of the vertices of said inner layer, and wherein each of the polygonal panels of the outer layer being shaped differently than each of the polygonal panels of the inner layer, and wherein the number of polygonal panels of said inner layer is different from the number of polygonal panels of said outer layer.
