My best friend from high school is a supervisor at the US patient office and has her patent law degree from George Washington but now gets to work from home so is back in town. She told me about how someone received a patent for "swinging side to side" on a common swing instead of swinging the standard way. They got it. Thank God it expired a few years back so I won't get sued when I show my granddaughter how to do it.
