Hello. TM is the abbreviation of TRADE MARK, which means "business mark" and is generally called "trademark". In China, the capital "TM" in the upper right corner of the commodity name indicates that the trademark is being registered and has not yet obtained the trademark certificate. So it is not protected by law. Different from circle R, 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, which has entered an objection period to prevent others from applying repeatedly, and it also means that the existing trademark holders have the priority to use it. The circle R in the upper right corner indicates that the trademark has been registered and obtained the trademark certificate. Therefore, only successfully registered trademarks are protected by law. China's Trademark Law stipulates that "a trademark registered with the approval of the Trademark Office is a registered trademark, and the trademark registrant enjoys the exclusive right to use the trademark and is protected by law". In other words, the actual use of a trademark does not have the effect of opposing trademark registration. Therefore, unregistered trademarks are always in a state of lack of rights protection, and may be banned at any time because others apply for registration of the same or similar trademarks.
