ROT STOP

What this record means

The record shows that “ROT STOP” is a live, Principal Register trademark owned by Rosen’s, Inc., a Minnesota corporation, and it was registered on October 6 2020 after filing on January 18 2019. The registration covers only one class – Class 001 – specifically “chemical preparations for use in agriculture, namely, chemical preparations for the treatment of seeds,” with a first use in commerce dated March 5 2020. Because the protection is limited to that agricultural chemical niche, a similar name used for unrelated products such as clothing, software or food would be far removed from the scope shown in the record, though the wording itself is not cleared for all uses. The prosecution history shows a normal examination path with an examiner’s amendment in March 2019, a statement‑of‑use filing, extensions, and final registration on the Principal Register; there is no supplemental‑register step to note. The most recent meaningful event is a Section 8 courtesy reminder emailed on October 6 2025, indicating the registration is still active. The supplied history contains no oppositions, cancellations or other enforcement actions. I'd treat this as a modest concern if you plan to market seed‑treatment chemicals under a similar name, but the risk drops sharply for other goods or services.
