WINTAINSerial 88357308 · Principal Register
Dead · Cancelled
Owner: Shenzhen Aicheyoupin Electronic Technology Co.,Ltd
Class 009 - Electrical & Scientific Apparatus
Filed Mar 26, 2019
Registered Oct 15, 2019
The record shows that the “WINTAIN” mark is cancelled, with the last status change on May 1 2026 when the registration was cancelled for failure to file a Section 8 declaration, and the owner listed is Shenzhen Aicheyoupin Electronic Technology Co.,Ltd. The registration covered a range of Class 009 items such as battery chargers, earbuds, headphones, microphones, rechargeable batteries, webcams, wireless chargers, wireless communication devices that transmit voice, data, images and video, audio speakers, computer mice, loud speakers and solar‑powered chargers. Because the goods are all electronic and scientific apparatus, a similar name used for products in that arena would create the closest record‑based concern, while uses outside those categories fall farther from the scope shown. The record does not give the owner control over every possible use of the word “WINTAIN.” No Supplemental Register filing appears, and the prosecution history simply tracks the normal examination and registration steps before the eventual cancellation. The supplied history contains no oppositions, cancellations by third parties or other enforcement actions. I'd treat this as a meaningful concern if you plan a comparable name for electronic devices, but the risk is lower for unrelated goods or services.
Full event history, owner details, and verdict inside.
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.
