What this record means
The record shows that “SERENADE” is no longer active – it was cancelled on Oct 22 2021 because the registrant, Avaya Inc., did not file an acceptable Section 8 declaration, so the Principal Register registration (No. 2274684) is dead. The registration covered only one class, 009, specifically “computer software for use in voice mail and voice messaging, electronic mail, automated attendant, interactive voice response and call processing, fax processing and integrated electronic mail and messaging services.” A similar name used for software or services in that communications‑technology niche would raise the closest record‑based concern, while uses in unrelated fields would be farther from the scope shown. The record does not give Avaya control over every use of the word “SERENADE.” There is no prosecution history indicating a Supplemental Register filing, and 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 same software‑for‑messaging space.
