As people have become aware of the importance of trademarks in recent years, a large number of companies or individuals have registered trademarks every day in recent years. And we all know that there is a principle in trademark application, which is the first-to-file principle. To put it simply, it means that whoever applies for a trademark of the same type or similar goods first will own it. But if the application is filed on the same day, which company does the trademark belong to? The "Trademark Law" stipulates that when applying for a trademark, two or more trademark applicants apply for registration of the same or similar trademarks on the same goods or similar goods, and the applicant shall be initially reviewed and announced. If the trademark is applied for on the same day, the previously used trademark will be initially reviewed and announced, and other applications will be rejected and will not be announced. If no evidence is used or the evidence is invalid, a draw will be used to determine whose application is valid. (To put it simply, it’s time to try your luck.) The actual determination process: 1. Determine based on the actual use evidence of the applied trademark. When encountering an application for a trademark on the same day, the Trademark Office will first require the trademark applicant to apply for a trademark within the specified time. Submit valid evidence of prior use of the trademark to determine who is eligible to apply for the trademark. 2. Friendly negotiation and self-resolution if both parties are unable to provide valid evidence, or use occurs on the same day. When there is no way to tell the winner due to use, etc., the two parties will discuss who will own the trademark, and then notify the Trademark Office in the form of a written agreement to decide who can be qualified to apply for the trademark. 3. Decision by drawing lots If you are unwilling or the negotiation fails, the Trademark Office will determine the applicant by drawing lots. After reading the above introduction, I believe everyone knows how to determine who the trademark ultimately belongs to when applying for trademark registration on the same day. There is nothing we can do about it. Therefore, if we want to register a trademark, we should register it as soon as possible to avoid unnecessary troubles and prevent some interested people from taking advantage of it!
