Hello! The trademark of Class 44 optical shop can be used as the signboard of the store name or background wall, but it cannot be used for optical products or eye packaging.

The Trademark Law stipulates that if a registered trademark ceases to be used for three consecutive years, its registered trademark shall be revoked by the Trademark Office. The Regulations for the Implementation of the Trademark Law stipulates: "Anyone who commits the act in Item (4) of Article 44 of the Trademark Law may apply to the Trademark Office to cancel the registered trademark and explain the relevant situation. The Trademark Office shall notify the trademark registrant to submit the evidential materials used before applying for cancellation of the trademark or explain the justified reasons for not using it within two months from the date of receiving the notice; If the evidence materials for use are not provided at the expiration of the period or the materials are proved invalid without justifiable reasons, the Trademark Office shall revoke its registered trademark. "

In other words, as long as your trademark is legally used in the category of goods approved by the Trademark Office, and you can provide evidence of effective use within three years to prove that the trademark is in normal use, it will not be revoked.

I hope my answer can help you, and I hope it will be adopted. Thank you!
