Water gun patents
Last updated on 2008-06-25
The Super Soaker 50 is a fairly well known patented item. But it is only one of the many patented water guns and far from the first or most interesting. There are loads of really interesting water gun patents out there that are great reading and viewing.
There never has been a truly comprehensive list of water gun related patents. These patents are great sources of information. They're historically interesting and also interesting from a design perspective. Because they are public domain, us here at Super Soaker Central have decided to list many patents to ease reading and locating them.
Since we only list patents by major brands or important patents either historically or scientifically, most patents display a released item. Some patents display something we've never seen before. These will be marked with "Unreleased" under the Water guns field.
Important note: We only list US patents simply because there aren't too many water guns in other patent systems.
