Frisbee False Marking Case

Interesting article in the WSJ about a false patent marking case involving Wham-O, maker of frisbees. The company is the latest defendant in a string of lawsuits against firms accused of marking their products with patent numbers that are long expired. The frisbee or “fying disc” was conceived by Walter F. Morrison in 1938. He patented the design in 1958, D183,626, and then sold the rights to Wham-O. There are over 200 patents classified in USPC 446/46, the main class for flying disc toys.
