Documents to be provided for trademark transfer include: an application for trademark transfer, which shall be stamped with the seals of the applicant and the assignee; Power of attorney for trademark transfer sealed by the transferee; A copy of the business license of the transferee, etc. After an enterprise stops operating or goes bankrupt, its intellectual property rights, including trademarks, can be transferred, and there are many cases. However, many domestic enterprises did not go to the relevant departments for cancellation procedures after they stopped operating, which led to the direct revocation of business licenses by the administrative department for industry and commerce. At present, in the case of trademark transfer, such problems have been encountered. A company has been revoked its business license for many years by the industrial and commercial department, and now it has encountered difficulties in the process of trademark transfer. In the process of examining and approving the trademark transfer application, the State Trademark Office stated that the trademark transfer notarial certificate must be provided in the trademark transfer application materials. However, the revoked enterprises face many difficulties in making notarization declaration of transfer. For example, most notary offices refuse to accept notarized cases of revoked enterprise trademark transfer. Therefore, if an enterprise wants to go through the trademark transfer formalities, it must first cancel the enterprise, and then take the enterprise cancellation form issued by the industrial and commercial department and notarize it by the resolution of the liquidation group. When applying for trademark transfer, the following materials shall be submitted at the same time: notarial certificate, enterprise cancellation form, qualification certificate of liquidation group, trademark liquidation resolution document and other related documents. Therefore, enterprises should submit cancellation applications to relevant departments in time after they stop operating, just like unused credit cards will face great risks if they are not cancelled in time. As an intangible asset, a trademark cannot be transferred because the company license is cancelled, which is a pity for enterprises, individuals and the trademark itself.
