The circled R on the drug packaging means: it means that the drug trademark is a trademark approved and registered by the trademark management authority in accordance with the law.
Trademark registration requires legal conditions and legal procedures. In countries that implement a trademark registration system, once a trademark is registered, it obtains the exclusive right to use the registered trademark and the right to prohibit others from using the same or similar trademark on the same goods.
The owner of a registered trademark shall enjoy the exclusive right to use the trademark in accordance with the law and shall not use the same or similar goods on the same or similar goods specified by the registered trademark.
Extended information:
If a natural person, legal person or other organization needs to obtain the exclusive right to use a trademark for its goods or services in production and business activities, it shall apply for trademark registration to the Trademark Office.
Trademark registration applications in a narrow sense only refer to trademark registration applications for goods and services, international trademark registration applications, certification trademark registration applications, collective trademark registration applications and special sign applications.
Trademark registration applications in the broad sense include not only trademark registration applications in the narrow sense, but also applications for trademark registration matters such as changes, renewals, transfer registrations, opposition applications, cancellation applications, and trademark use license filings.
