Registered trademark

Registered trademark refers to a trademark that has been approved and registered by the trademark management agency in accordance with the law. Registration of a trademark requires legal conditions and legal procedures. In countries with a trademark registration system, once a trademark is registered, it acquires the exclusive right to use the registered trademark and the right to prohibit others from using a trademark that is identical or similar to the registered trademark on the same or similar goods.

The origins of trademarks date back to ancient times, when craftsmen imprinted their signatures or "marks" on their works of art or utilitarian products. These marks evolved into today's trademark registration and protection system. This system helps consumers identify and purchase a product or service because the nature and quality of the product or service indicated by the trademark meet their needs.

The Implementation Regulations of China's Trademark Law stipulate that when using a registered trademark, a "registered trademark" or registered mark may be indicated on goods, product packaging, instructions or other attachments. Some trademarks are marked with TM in the upper right corner. TM is the abbreviation of TRADEMARK. American trademarks are usually marked with TM, which does not necessarily mean a registered trademark.
