Westmoreland was very active in its early dates in procuring design patents. This album shows the various glass designs that were invented and produced by Westmoreland. A design patent gave the company typically a 3 1/2 year exclusive right to use that particular design without fear of another glass company copying and producing the same item or decoration.
