Appeal No. 95-1186
Application No. 08/051,797
the spacing between patches within a group, we fail to find a
prima facie case of obviousness. We are unpersuaded,
particularly in view of appellants’ challenge [reply brief-

expedients” since we have no evidence before us that the prior
art recognized any advantage to be achieved by spacing
adjacent groups of patches further apart than the spacing
between patches within an individual group.
