Problem

We request previously undiscovered prior art (If you are new, see: patent and prior art basics and tips for Patexia's prior art contests) including patents and non-patent literature (English and foreign language) that can help invalidate claim 1 of US patent 7,900,867 (‘867) - Personal propulsion Device. 

The patent describes a wearable water “jetpack” propulsed by pressurized water pumped from an auxiliary unit. The best qualifying submission is guaranteed to receive the prize. The following questions will help you understand what we are looking for in this study.

The reference(s) should clearly satisfy the following:

  • Describes a water jetpack that operates similar to this product
  • The water jetpack uses a pump system with a source of water
  • The pump system is connected to the jetpack through a tube or hose.

Contest entries can alternatively include a combination of several references from which the above system is obvious.
