Trademark — Wi-fi

However, from a pure intellectual property law perspective, the Wi-Fi trademark is a weak and vulnerable asset. If the Wi-Fi Alliance ever tried to sue a small blogger for using "Wi-Fi" in a domain name or a product listing in a generic way, they would likely lose. The mark is in a state of "liquid genericide"—it hasn't dissolved entirely because no one has forced the issue in a major federal court. It survives on borrowed time and goodwill.
