The difference between TM and R trademarks is different marks and different legal effects.

1. The R trademark is different from the TM trademark.

R trademark circle r, TM trademark with the letter TM.

2. The legal effect is different.

the r mark has the characteristics of exclusiveness, exclusivity and uniqueness, and belongs to the owner of the registered trademark, which is protected by law. No enterprise or individual may use it by itself without the permission or authorization of the owner of the registered trademark, otherwise it will bear the tort liability.

TM logo can play a certain protective role, but if the trademark is not approved and registered by the Trademark Office, its legal protection is not strong, and only when the unregistered trademark reaches a certain popularity can it get legal protection to a certain extent.

Trademark registration should follow the following principles:

1. The principle of combining voluntary registration with compulsory registration. Most trademarks in China adopt the principle of voluntary registration. Producers and operators of goods that must use registered trademarks according to the laws and administrative regulations of the state must apply for trademark registration. Without approval, goods may not be sold in the market.

2. the principle of salience. The trademark applied for registration shall have distinctive features and be easy to identify, and shall not conflict with the legal rights (such as design patent right, name right and copyright) previously obtained by others.
