The validity period after trademark registration depends on the national or regional trademark law and the trademark registrant's compliance with relevant renewal procedures.

Generally speaking, the validity period of a trademark after registration is 10 years. During this 10-year period, the trademark registrant enjoys exclusive rights to the trademark and can use and protect the trademark.

After the trademark registration expires, the trademark registrant can choose to renew the trademark registration. The renewal period and procedures vary from country to country or region, and an application for renewal usually needs to be submitted within a certain period before the trademark registration expires.

Renewal of trademark registration can extend the validity period of the trademark. If the trademark registrant renews the trademark registration on time, the validity period of the trademark can be extended indefinitely.

It should be noted that trademark registrants must comply with the requirements for renewal procedures and pay the corresponding fees on time. If the trademark registrant fails to renew the trademark registration on time, the trademark may become invalid and the protection of the trademark will be lost.

For specific trademark registration validity period and renewal requirements, please consult the local trademark registration agency, intellectual property office or professional lawyer to understand the accurate regulations and procedures.
