1987 Improved disposible diaper with pocket for wipes

In 1987, Curtis filed a US patent application that subsequently issued as Patent No. 4,753,647. This is a modification of a diaper with a moisture-proof pocket containing wipes that can be taken out and used with one hand. Curtis refused to allow her invention to be marketed until companies started selling biodegradable diapers. The full statutory term of this patent expired February 20, 2007, and it is now in the public domain. She filed a second US patent application related to disposable diapers in 2016 which issued as US Patent 9,827,151.
