SERENADE BIOFUNGICIDE

What this record means

The record shows that “SERENADE BIOFUNGICIDE” is a cancelled Principal Register registration (status “dead”) owned by Bayer Cropscience LP, with the cancellation dated Feb 25 2022 because the required Section 8 declaration was not filed. The registration covered Class 005 – “biological pesticides for agricultural, commercial and domestic use” – so a later mark using the same or similar wording in the same field would raise the closest record‑based concern. The record does not give Bayer control over every possible use of the words “Serenade” or “Biofungicide” outside that specific pesticide context. This mark never appeared on the Supplemental Register, so there is no descriptiveness‑to‑supplemental sequence to note. The prosecution history contains no oppositions, cancellations by third parties, or other enforcement actions, indicating no visible enforcement signal. I'd treat this as a meaningful concern if you plan a similar name for agricultural pest‑control products.
