If the use of the trademark infringes upon the exclusive rights of others to use the trademark, it will not affect the investigation and punishment of the behavior by the relevant industrial and commercial administrative authorities. 8. If the applicant needs to conduct trademark inquiry, he can go to the inquiry window of the trademark registration hall before applying. The prior rights information provided in the inquiry is for reference only by the inquirer. 9. The validity period of a registered trademark is 10 years, calculated from the date of approval of registration. If the registered trademark expires and needs to be continued to be used, the registrant should apply for renewal of registration within 6 months before expiration. If the registrant fails to submit a renewal application during this period, it can submit it within the 6-month extension period after the expiration, but must pay the renewal registration delay fee. If a renewal application is not submitted after the extension period expires, the Trademark Office will cancel the registered trademark; if the registrant wants to continue to use the registered trademark, he must resubmit a registration application.
