Facts

This case involves a patent infringement action concerning Patent No. 3,002,240, which pertains to a closure device for sealing plastic bags. The plaintiff, John L.

The defendant, Shelly Bros., Inc., was accused of infringing the patent by using a device supplied by Union Paper Company.

Analysis

In this case, the court determined that the teeth and ridges, which were material elements of the patent, were omitted in the defendant's altered device. The court applied the doctrine of equivalents narrowly, concluding that the removal of these elements constituted a significant change that avoided infringement. Furthermore, the plaintiff's failure to comply with marking requirements precluded recovery for damages prior to actual notice of the patent to the defendant.

Who won?
