USPTO today issued "nine millionth" patent US 9,000,000 for "Wind-shield washer conditioner". The patent was filed by Inventor Matthew Carroll of FL (assigned to WiperFill Holdings). It took just 4 years for USPTO to issue the last one million Patents. That's one big achievement of the US Government and it sets them apart from the rest of the world. It is no doubt that Innovation fuels up the economy like nothing else and the entire US economy now harvests the fruit of Intellectual Property. The US Patent office employs over 8000+ Patent Examiners and rigorously tries to improve upon pendency of applications by incentivizing Examiners, preventing re-work and even allowing them to work from home.
