Ratio Decidendi

The court found that the defendant's banner did not infringe the plaintiff's patent 97/10535 because an essential integer—the pole being adapted to engage the upper periphery of the material—was absent; the defendant's product used a sleeve on the material to engage the pole, not vice versa. Although the pole maintained tension, this was not sufficient for infringement as all essential features must be present. Regarding design registration A97/1155, the court held that the defendant's banner was not substantially different from the registered design, but the design lacked novelty due to prior art (the Rehbein patent), which depicted a similar tear-drop shaped flag.
