The evidence provided by the trademark registrant shall be true, valid and legal. Note: As it has been discontinued for three consecutive years, the registrant needs to prove that it has been continuously used for nearly three years when submitting evidence. The previous evidence is invalid, and even if it is submitted, the State Trademark Office will not accept it. In view of the application for cancellation of a registered trademark for three consecutive years, it is suggested that the trademark registrant should entrust a professional trademark agency to collect and submit valid evidence within a time limit after receiving the notice of proof from the State Trademark Office. Generally speaking, the evidence of trademark use focuses on: (1) the use of trademarks on commodities, commodity packaging, containers and related transaction documents (such as signs, product descriptions, manuals, sales agreements, bills, etc.). ); (2) Evidence forms of using service marks include (decoration of service places, menus, posters, price lists, documents, service agreements, etc.). ); (3) The forms of evidence for the use of advertisements include advertisements, exhibition materials, photos, and approval documents from the competent authorities in the media such as radio, television, magazines, newspapers and billboards.

Article 24 of the Trademark Law of People's Republic of China (PRC) where the logo of a registered trademark needs to be changed, a new application for registration shall be made. Article 49 of the Trademark Law of People's Republic of China (PRC) * * * If a trademark registrant changes the registered trademark, the name, address or other registered items of the registrant during the use of the registered trademark, the local administrative department for industry and commerce shall order it to make corrections within a time limit; If it fails to make corrections within the time limit, its registered trademark shall be revoked by the Trademark Office.
