What this record means
The record shows that RONZLLA is a live, Principal Register trademark owned by Shenzhen Rooder Technology Co., Ltd, and it has been registered since January 24 2023. The registration covers Class 009 goods – specifically microphones, vehicle batteries, battery chargers, eyeglasses, bicycle helmets, motorcycle helmets, reflective safety clothing, safety helmets and USB cables – so a later use of “RONZLLA” for any of those items would raise the closest record‑based concern. The record does not give the owner control over every possible use of the word, only over the listed goods. The prosecution history shows the application was filed on November 30 2021, went through an office action in August 2022, was approved for publication in October 2022 and then registered, but there is no supplemental‑register filing to note. The most recent meaningful event is the notice of registration confirmation emailed on January 24 2023, and the supplied history shows no oppositions, cancellations or other enforcement activity. I'd treat this as a meaningful concern if you plan to use a similar name for comparable electronic or safety equipment.
