Time:2026-01-06 Views:2
Background of Trademark Infringement Cases
In the current context of globalization, cross-border trademark infringement cases are increasing. Law firms providing overseas services in trademark infringement prosecutions require sufficient evidence to ensure the smooth progress of the case.
Trademark registration certificate
To file a trademark infringement lawsuit, you must first provide proof of trademark registration, including a registration certificate and proof of trademark use. These documents form the basis of a trademark infringement lawsuit, proving trademark ownership and the lawful use of the trademark in the jurisdiction in question.
Infringement evidence collection
The law firm needs to collect and organize evidence of the trademark infringement involved, including the time and location of the infringement, the specifics of the infringing goods or services, and the identity of the infringer. This evidence will help prove the facts of trademark infringement and provide strong support for the prosecution.
Witness testimony
In trademark infringement cases, witness testimony is a crucial piece of evidence. Law firms must locate and obtain witness testimony to establish ownership, legal use, and the facts of infringement. The authenticity and credibility of witness testimony can have a significant impact on the outcome of the case.
Expert appraisal report
To further verify the legality of a trademark and the damage caused to trademark rights by infringement, a law firm may commission an expert to conduct an appraisal and provide the expert's appraisal report as evidence. The professionalism and objectivity of the expert's appraisal report will help the court make an objective and fair ruling on the case.
Relevant contracts and communication records
The law firm also needs to collect contract documents and communication records related to the trademark in question. These documents can prove the transfer, licensing or cooperative relationship of trademark rights, further establish the ownership of the trademark, and also prove the breach of contract by the infringing party.
Evidence of Damages
Finally, the law firm must provide evidence related to the damages caused by the trademark infringement, including the economic value of the trademark rights, the economic losses caused by the infringement, and the basis for calculating other damages. This evidence is key to suing for trademark infringement and obtaining financial compensation.
In overseas trademark infringement lawsuits, sufficient, legal, and valid evidence is essential for success. Law firms must carefully analyze the chain of evidence to ensure its authenticity and reliability, thereby increasing their chances of success.
