ROBOLUXSerial 79020409 · Principal Register
Dead · Cancelled
Owner: Bürkert Werke GmbH
Class 006 -
Class 020 -
Filed Oct 19, 2005
Registered Jul 03, 2007
The record shows that the mark “ROBOLUX” is no longer live; it was cancelled on October 20, 2025 because the corresponding international registration was cancelled. The owner listed is Bürkert Werke GmbH. The mark covered manually operated metal valves and plastic valves that are not machine parts, classes 006 and 020. A similar name would raise the closest concern in those specific valve‑related goods. The record does not give the mark control over all uses of the word “Robolux.” The prosecution history indicates that the mark was initially refused for descriptiveness, then amended to the Supplemental Register, and later moved to the Principal Register before cancellation; this sequence is shown but does not imply any special status beyond what the record states. The latest meaningful event was the cancellation notification on May 7, 2026. No opposition, court action, or other enforcement activity appears in the supplied history. For someone considering a similar name, the cancelled status means the mark is no longer enforceable, but the specific goods listed still represent the closest area of concern.

The way I'd use it, honestly, is as the thing you attach when a bank, a marketplace, or a co-founder asks "are we clear on the name". It answers in one page.
