The record shows that the mark “TOPCABIN” is live and registered on the Principal Register under serial 86591631, owned by Cai, Liang Sen, an individual. The registration covers a wide range of bicycle‑related goods, including air pumps, baskets, bells, brake lever grips, frames, handlebar grips, kickstands, pedals, and various bicycle parts and accessories, as well as cell phone cases adapted for bicycles. A similar name would raise the closest concern in the bicycle equipment and accessories market, especially where the goods overlap with those listed. This record does not give the owner control over every use of the word “TOPCABIN” in all contexts. The prosecution history shows a straightforward acceptance of the application and subsequent renewals; no Supplemental Register steps are involved. The latest maintenance event was the renewal on February 7, 2026, with the next renewal due in 2036. No enforcement actions appear in the supplied history. For someone considering a similar name, the presence of this active registration in the bicycle‑equipment field suggests a meaningful risk of infringement if the new use is in a related category.

The way I'd use it, honestly, is as the thing you attach when a bank, a marketplace, or a co-founder asks "are we clear on the name". It answers in one page.
