The PCK certificates expire every 7 years. However, the evidence to validate the client platforms, i.e. TCBInfo, QEIdentity, QVEIdentity and Certificate Revocation Lists, expires every 30 days. As a service owner, you should download these frequently to ensure you are attesting only the latest known compliant platforms.
