America's 9-millionth patent is a windshield-wiper fluid reservoir
This week, America celebrated its 9-millionth patent. The invention comes from Matthew Carroll of Jupiter, Florida, who developed a method for using rainwater to replenish windshield wiper fluid and, for the past three years, has been shepherding his invention through the US patent system. He first filed for the patent on March 12th, 2012, through his company WiperFill LLC. The patent was granted on April 7th, the 9,000,000th such application granted since 1836, when the Patent Office began its current numbering system.
