Hello, landlord! The detailed answer is as follows: I think the official correct solution "TM" is the abbreviation of English "trademark". It is the abbreviation of English "register". "TM" and "r; Have played a suggestive role. It usually appears in the upper right corner or lower right corner of some signs. " TM "means that the logo is used as a trademark, while" R "means that the logo is already a registered trademark and enjoys the exclusive right to use the trademark. It has been pointed out that "TM" means that the trademark has been applied to the State Trademark Office, and the State Trademark Office has also issued the Notice of Acceptance of Trademark Registration, that is, the Notice of Acceptance of Trademark Registration is the premise of using the "TM" logo. Actually not: China's opinion on "R; "There are clear regulations on the use of TM, but there are no regulations on the use and management of TM. As long as the operator wants to inform others that a logo is used as a trademark, TM can be used regardless of whether the logo applies for trademark registration. Excerpt from: www.whsbzl.com
