Matt Van Gundy writes "In another brilliant move by the well loved U.S. Patent and Trademark Office a patent (6,368,227) has been granted to a Mr. Steven Olson for inventing the method of swinging sideways on a swing. The patent even lays claim to "inducing a component of forward and back motion into the swinging motion, resulting in a swinging path that is generally shaped as an oval." I claim prior art, but perhaps I am one of the few fortunate ones who enjoyed this method of swinging long before its 'invention' by Mr. Steven Olson. " My favorite line from the patent : "The user may even choose to produce a Tarzan-type yell while swinging in the manner described, which more accurately replicates swinging on vines in a dense jungle forest. Actual jungle forestry is not required."
