Trademark search can only search for trademark information that has been entered into the database, so there is a blank period, or a blind spot. Generally, a similar trademark search is done 4 to 6 months after the trademark application to enhance the success rate of trademark registration. Article 28 of my country's Trademark Law stipulates that if a trademark applied for registration does not comply with the relevant provisions of this Law or is identical or similar to a trademark that has been registered or preliminarily approved by others on the same or similar goods, the trademark shall be replaced by a trademark. The Bureau rejected the application and did not make an announcement. Therefore, an inquiry should be made before applying, so that the trademark can obtain a trademark certificate to the greatest extent possible. At the same time, it generally takes nearly a year for a registered trademark to be accepted by the Trademark Office and announced. If the registered trademark is rejected without inquiry, , not only wasting money, but more importantly, wasting time and delaying the use of the trademark.
