# Trademark Infringement: Trademark infringement happens when you use a trademark owner's trademark or a similar mark in a way that is likely to confuse the public into believing that the trademark owner is the source or sponsor of your products or services. This is the most common type of trademark claim, and it effectuates trademark's primary purpose of avoiding consumer confusion. See What Trademark Covers for details.
# Trademark Dilution: Trademark dilution happens when you use a trademark owner's famous trademark in a way that is likely to weaken its capacity to identify the trademark owner's goods or services or to tarnish the wholesomeness of the mark. The trademark owner need not show that you created consumer confusion, and dilution may occur even if your goods or services are completely different from the trademark owner's. Because of dilution law, it's probably not a good idea to call a blog "Kodak News" or "McDonald's Blog," unless it is actually about Kodak or McDonald's (in which case you should read Using the Trademarks of Others carefully). For details on trademark dilution, see What Trademark Covers.
# Cybersquatting: Cybersquatting happens when you register, use, or sell a domain name with the intent to profit from someone else's trademark. Congress passed the Anticybersquatting Consumer Protection Act in 1999 to stop speculators from buying up multiple domain names and selling them at exorbitant prices to the legitimate owners of the associated trademarks. If your use of a trademark owner's trademark in a domain name does not fit this stereotypical model, you should be able to avoid cybersquatting liability. For details, see the Cybersquatting section.
