3.1. Logo Usage and Trademark Information
Many geocachers want to use our logos for various geocaching-related thingsand we love that! But before you do, keep in mind that the CITO logo (and the name Cache In Trash Out) is our trademark and the Geocaching logo is our registered trademark in the United States and many other countries around the world. Trademark law requires us to set a few ground rules that you must agree to before using our logos.
Read our Logo Usage Guidelines: http://www.geocaching.com/about/logousage.aspx
There is also a public domain logo which was independently produced. We do not manage this at all. It is used widely and is often seen with some small variation such as color, or a graphic background. More information on the public domain logo is available at http://bytethebullet.com/geologo.
