What this record means
The record shows that “FLOWERING SYSTEM” is cancelled; the registration was on the Supplemental Register (Reg. No. 4081425) for Advanced Nutrients Ltd., a Canadian corporation, and it was cancelled on Aug 10 2018 because the owner did not file a required Section 8 declaration. The only goods listed are “plant nutrients, namely, fertilizers and soil additives” in International Class 001, so a similar name used for anything in that category would be the closest record‑based concern, while uses in unrelated fields fall farther from the scope shown. The prosecution history indicates the application was filed Apr 16 2009, later amended and approved for Supplemental Register registration on Jan 3 2012 after a descriptiveness issue, and then remained alive until the Section 8 cancellation. No oppositions, cancellations by third parties, or court actions appear, so the supplied history shows no enforcement activity. I'd treat this as a meaningful concern if you plan a name for fertilizer‑type products, but the record does not control every possible use of the words.
