This problem should be divided into two parts: one is that the hats have the same style; the other is that the hats have different trademarks.

1. The styles of the hats are the same; the style of the hat can be regarded as a new aesthetic design created by the shape, color, pattern or combination of the product of the hat, which involves this hat design rights. If a relevant design exists and is within the protection period, it constitutes design patent infringement. In addition, if the overall composition of this hat has been applied for trademark registration and its use has not been authorized by the rights holder, it will constitute trademark infringement.

2. The trademarks of the hats are different; it needs to be clarified whether the "different" referred to here covers "similar trademarks", if the two trademarks are not completely identical, but are similar in whole or in part A trademark that is likely to cause confusion in market transactions, and such use is not authorized by the trademark registrant, will still constitute trademark infringement. See Article 57, Paragraph 1, Item 2 of the Trademark Law, “Using a trademark that is similar to the registered trademark on the same kind of goods without the permission of the trademark registrant, or using a trademark that is the same or similar to the registered trademark on similar goods. , which can easily lead to confusion.”
