When is the validity and renewal of Mexican trademark registration?

Trademarks and advertising slogans are valid from the date of application 10 year, and the validity period after each renewal is also 10 year. The application for renewal shall be filed within the grace period of six months before the expiration of the registered trademark or six months after the expiration, otherwise the registration shall be invalid. When applying for renewal, the certificate that the trademark has been used continuously for at least 3 years within the validity period of registration and the certificate that the renewal fee has been paid shall be attached. Where the same trademark registration protects two or more categories of products or services, the renewal only needs to be carried out in one category, and the relevant fees shall be paid.
