legal analysis: it usually takes 13 to 21 months for a trademark TM to reach R. "TM" is a trademark logo and "R" is a registered trademark. Marking TM only means that this logo is being used as a trademark, and its function is that the marked graphics or words are the logo of this commodity or service, which may not be registered or is applying for registration. R is a commodity or service marked with this mark, but the marked figure or text is not only a trademark logo, but also a registered trademark, which is protected by national laws and cannot be used by any other individual or organization without authorization.

legal basis: article 28 of the trademark law of the people's Republic of China, the trademark office shall complete the examination of the trademark applied for registration within nine months from the date of receiving the application documents for trademark registration, and make a preliminary examination and announcement if it meets the relevant provisions of this law.
