ROT-GARD

What this record means

The record shows that ROT‑GARD is a cancelled Principal Register registration (status “dead”) owned by JH Biotech, Inc., a Delaware corporation, and it is no longer in force. The registration covered only one class – Class 001 – specifically “biological preparation to prevent fungal diseases on plants,” with the first use dated February 1 1990. Because the protection was limited to that narrow agricultural biotech description, a similar name used for anything outside that field would be the closest record‑based concern, but the record does not give the owner control over every use of the word “ROT‑GARD.” The prosecution history shows the mark was granted on October 27 1992, renewed in 1997, and then cancelled on August 2 2003 when the required Section 8 declaration was not filed. The supplied history contains no oppositions, cancellations by a third party, or other enforcement actions. I'd treat this as a meaningful concern if you plan to market a plant‑protectant product under a similar name.
