Yes, it's true. E-cert can be printed anytime and anywhere, which is more convenient and not afraid of loss. At the same time, the two-dimensional code on the certificate can be linked to the website of the Trademark Office to check the authenticity, and the effect is the same as that of a paper certificate.
