"Products or services that wish to use the name MAME or a derivative thereof must obtain explicit permission from the trademark owner (Nicola) to do so in all cases.
In most cases, if a product or service has a legitimate use, abides by the MAME license, and adheres to the spirit of MAME and the guidelines expressed in the About MAME section, obtaining permission should not be difficult. If you believe you have a legitimate need to use the MAME name, please contact the team using the contact form to request permission.
If you are interested in helping stamp out unauthorized use of the trademark, use the contact form to report abuses. "
MAME seems to offer a mechanism for this. One of the selections is: Request permission to include MAME with a product. That being said, they also offer a way of checking up on licensees through this same form...
