Legal analysis: After the trademark is successfully registered, there is no need for annual review. The trademark registration is valid for ten years and you can apply for renewal one year before it expires. If there is no renewal after the expiration, there will be a six-month extension period. If the extension period has expired and has not been renewed, the trademark will be invalid
