If you possess a federally registered trademark on the name, and the domain owner does not, you may have legal rights to the domain name. If this is the case, you should seek the advice of a trademark attorney. Domain Names can be creative or generic. Like real estate, domain names can be leased or resold for profit. If the name you desire is already registered, you may want to make an offer to buy the name from the present owner.
Generic name can sometimes be more marketable than a creative names.
It's likely that this is a fraction of what good generic and creative domain names will sell for in the next century. If you're taking a wait and see attitude, be forewarned. This is a phenomenal increase over just a few years ago, and good dot com names are going very fast. All rights reserved.
