What Class 6 covers

Class 6 of the international (Nice) trademark classification is Common metals & hardware. In practice, that's where you'll find brands for goods and services in the "common metals & hardware" category. Every US trademark application declares one or more of the 45 classes, and the class is what decides whether two similar names actually conflict — DELTA for faucets and DELTA for airlines coexist because they're in different classes.

Why the class matters for monitoring

A new filing that's identical to your name but in an unrelated class is usually a curiosity. A merely similar name filed in Class 6 — your class — can be the real problem. That's why MarkAlarm weights class overlap heavily: same-class look-alikes can reach high-priority alerts, while different-class ones stay low — once you tell it which classes you sell in. A watch left open to all 45 classes has no class signal to weigh, so an identical name anywhere can still score high; setting classes is what turns the volume down. If your brand lives in Class 6, watching new filings in it is how you catch a conflict inside the 30-day window instead of months later.
