For a registered trademark that has been revoked because the registrant did not comply with the regulations on the use of registered trademarks, or a trademark that has been canceled because the registration validity period has not been renewed, the exclusive right to use the trademark has been extinguished. However, in order to prevent confusion about the origin of the goods, this article stipulates that within one year from the date when the aforementioned trademarks are deregistered or canceled, the Trademark Office will not approve the application for trademark registration that is identical or similar to these trademarks, that is, it will not be registered. The reason for this provision is that after a trademark registration is revoked or canceled, the goods produced by the original registrant using the registered trademark cannot be withdrawn from the market immediately. If other companies are approved to register the same or similar trademark at this time, it may Products with the same or similar trademarks produced by different companies appear on the market at the same time, thus causing confusion among consumers. In order to prevent this situation, this article stipulates a one-year period during which the Trademark Office will not approve applications for identical or similar trademarks submitted by others. After this period, the original registrant's goods are generally sold out and are not subject to this regulation. In addition, this provision only restricts the Trademark Office from approving the registration of such trademarks within the specified period, but does not prohibit the Trademark Office from accepting registration applications for such trademarks.
