Bullet About these patents

Patent number: 000000

These are not real patents. But these are ideas and sketches that are covered by regular copyright.

Patents are weird things. The current patent system is one big failure. It is possible to file a patent for something that is in common use. That is why I offer the patents on this page under the normal copyright, with an added Creative Commons license.

To make use of these patents possible, they are published under the Creative Commons 3.0 BY-SA license. You are free to make remixed work of these patents or to publish them, as long as my name is mentioned. Have fun!
