Infringement after trademark registration may lead to infringement liability. The specific liability methods and consequences may vary depending on the country/region's legal system and the specific circumstances of trademark infringement.

Generally, when the holder of a trademark right discovers that others have infringed upon his trademark, he can take the following measures:

1. Issue a warning letter: The holder of the trademark right A written warning letter can be issued to the infringing party, requiring it to stop the infringement and bear corresponding legal liability. Warning letters typically include a specific description of the infringement, a statement requesting that the infringement cease, and the threat of possible legal action.

2. Negotiated settlement: The trademark holder and the infringing party can try to resolve through negotiation, such as reaching an agreement where the infringing party stops using the trademark, pays compensation, or reaches other forms of settlement agreement. This usually requires both parties to negotiate and negotiate on issues such as the infringement and the amount of compensation.

3. File a lawsuit: If the warning letter or negotiation fails to resolve the dispute, the trademark right holder may choose to file a lawsuit in court to seek legal protection and infringement compensation. Litigation procedures usually include filing of a complaint, court hearing and judgment. The court may order the infringing party to cease the infringement, pay compensation or other forms of relief.

It should be noted that the holder of trademark rights needs to take appropriate actions in accordance with local legal regulations and procedures. The specific method of bearing tort liability and the amount of compensation may also vary depending on factors such as the nature of the infringement, the degree of fault of the infringing party, and the extent of the damage caused.

If you find that someone else has infringed your trademark after registering it, it is recommended to consult a professional intellectual property lawyer to obtain relevant legal advice and take appropriate legal action based on the specific situation.
