What this record means
The record shows that “SERENADE” is a cancelled Principal Register registration (status “dead”) owned by MAAX BATH INC., a Canadian corporation, and it was removed on Oct 20 2017 because the required Section 8 declaration wasn’t filed. The registration covered only Class 011 goods—baths, bathtubs, whirlpool baths and bath installations—so a similar name used for plumbing fixtures or bathroom equipment would raise the closest record‑based concern, while uses in unrelated categories fall farther from the scope shown. The record does not give the owner control over every possible use of the word “SERENADE.” No Supplemental Register filing appears, and the prosecution history simply tracks the normal filing, allowance, registration and the later Section 8 cancellation. The supplied history contains no oppositions, cancellations by third parties or other enforcement actions. I’d treat this as a meaningful concern if you plan a name in the bathroom‑fixture market, but the risk drops sharply for dissimilar goods.
