If the company changes and the trademark needs to be changed, according to my country's "Trademark Law", if the registered trademark needs to change the name, address or other registration matters of the registrant, a change application should be submitted. When transferring a registered trademark, the transferor and the transferee shall sign a transfer agreement and submit applications to the Trademark Office at the same time. The transferee shall ensure the quality of the goods using the registered trademark. When transferring a registered trademark, the trademark registrant shall transfer all similar trademarks registered on the same goods, or identical or similar trademarks registered on similar goods. For transfers that are likely to cause confusion or have other adverse effects, the Trademark Office will not approve the transfer and will notify the applicant in writing and explain the reasons. After the transfer of a registered trademark is approved, it will be announced. The assignee shall enjoy the exclusive right to use the trademark from the date of announcement.
