Hello, it is not a patented trademark. I found information about the IZUNO trademark on the official website of Bajie Intellectual Property. The query result is: Chongqing Mingliang Glasses Co., Ltd. applied for the name "Minggliang" on 2011-04-20 The trademark "Bright Glasses M" passed the review of the Trademark Office on 2014-01-27 and issued a registration certificate on 2014-04-28. The latest status is that the trademark registration application has been completed; the period of use is 10 years at 0024- Expires on 04-27. Hope to adopt it, thank you!
