Judging from what you said. Snowflake litigation trademark pattern infringement may refer to appearance patent infringement. I query bought the trademark of Koda Saixue, and found that Saixue had only Chinese characters, but no patterns. Therefore, there will be no infringement of trademark patterns. Moreover, even if Saixue has a pattern, the Trademark Office approved the registration of Saixue trademark, indicating that Saixue can be used normally and legally. For the infringement of appearance patent, regardless of the product quality, the manufacturer should bear the responsibility.
