If your company owns the copyright earlier than their trademark registration application, you can object or cancel their trademark. Copyright is a registration system. Copyright registration is generally only subject to formal review, so as long as the trademark design meets the formal requirements of copyright, it can be registered. If that company's trademark does plagiarize a copyrighted trademark design, the company can file an objection application within 3 months of the preliminary trademark review announcement, or file an application to cancel its trademark after registration. As long as it can be proven that your company's trademark design owns the copyright and it was filed earlier than he applied for trademark registration, whether the copyright is registered or not is not critical. Article 31 of the "Trademark Law" "Application for trademark registration shall not damage the existing prior rights of others", and the "prior rights" include copyrights.
