Hello, the ceramic tile with the diameter symbol trademark is Asian ceramic tile. I found the information about Haoyunlai trademark on Bajie Intellectual Property official website. The query result is: Shanghai Asia Ceramics Co., Ltd. applied for the trademark named "Asia" on April 29, 21, and the trademark passed the examination of the Trademark Office on April 14, 22, and issued the registration certificate on July 15, 22. At present, it is the latest. The service life is 1 years and expires on July 13th, 222. Hope to adopt, thank you!
