Audigon is a trademark, or to give the subspecies, a service mark. The purpose of a service mark is to identify the source of the services being offered. The strongest type of trademark is completely arbitrary. A valid trademark cannot describe an ingredient, quality, function, purpose, feature, characteristic or use of the specified goods or services. It suggests in the vaguest sort of way that the services are associated with audio, but fundamentally it's a made-up word that tells you these services are being offered by the Audigon.com company, and it symbolizes the goodwill that company has earned, supposing that it has.
