Timeliness refers to the term of validity of the exclusive right to use a trademark. During the period of validity, the exclusive right to use a trademark is protected by law. If it is not renewed after the period of validity, it will no longer be protected by law. Trademark laws in various countries generally stipulate the protection period of the exclusive right to use a trademark. Some countries set a longer time limit, while others set a shorter time limit, ranging from 20 to 7 years, mostly 10 years. China's Trademark Law stipulates that the exclusive right to use a trademark is valid for ten years. Article 38 of the Trademark Law stipulates: "Where a registered trademark needs to be used continuously after its expiration, it shall apply for renewal of registration within six months before its expiration. If the application is not made within this time limit, a grace period of 6 months can be given. If no application is made at the expiration of the exhibition period, its registered trademark shall be cancelled. Each renewal of registration is valid for ten years. After the renewal of registration is approved, it will be announced. "
