Trademark - Wi-fi

The legal risk is enormous. In many jurisdictions, a trademark can be cancelled if it becomes the common descriptive name of the product. By any objective measure, "Wi-Fi" is now the generic term for wireless local area networking. Consumers do not ask, "Does this router support the IEEE 802.11 standard as certified by the Wi-Fi Alliance?" They ask, "Does it have Wi-Fi?" Courts have historically ruled against marks like "Thermos" and "Cellophane" for this exact reason.

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. wi-fi trademark

In the pantheon of modern technology trademarks, few names are as ubiquitously recognized as "Wi-Fi." It sits alongside "Kleenex," "Xerox," "Google," and "Photoshop"—brands so successful they have transcended their legal status to become verbs or generic nouns. However, unlike those other examples, the story of the Wi-Fi trademark is less a tale of a corporation defending its castle and more a fascinating case study in strategic non-enforcement, accidental branding, and the razor-thin line between genericization and enduring trademark status.
