Copyright VS. Trademark?

[bcnu]

Depending upon your circumstances you may already have valuable trademark rights and copyrights that have been infringed. Look into the trademark coverage of "look and feel" of a venue, and the "trade dress" of your party that reaches the level of being recognizable as your creation.

If you were the first, you own the rights. Start filing registrations, so they don't "beat you" to the punch. Calculate a realistic licensing fee for your "franchise" (say, $25,000 for the look and feel, plus ten percent of any gate) and have an attorney draft a cover letter offering them the license.
