Evidence Required for Overseas Service Trademark Infringement Investigations
Overseas service trademark infringement investigations require sufficient evidence to support related legal proceedings or mediation. The following are key evidence that a law firm may need in an overseas service trademark infringement investigation:
Official trademark registration certificate
First, ensure you have verified the official registration certificate for the trademark in question. This certificate provides definitive proof of trademark ownership, confirming key information such as the registrant, registration date, and trademark category. In overseas service mark infringement cases, the trademark in question must be legally registered to be protected.
Evidence of trademark use
In addition to the registration certificate, evidence of trademark use is also a key factor. Investigators need to collect information on the use of the trademark in the market, product packaging, advertising, and other related materials. This evidence can demonstrate the actual use of the trademark and its popularity and influence among consumers.
Evidence of infringement
Investigators must collect relevant evidence to prove the alleged infringement. This includes, but is not limited to, information on the infringer's trademark usage, sales channels, and sales volume. They must also compare the similarity and potential for confusion between the two trademarks, as well as the losses incurred by the infringement on the original trademark owner.
Witness testimony
In overseas service trademark infringement cases, witness testimony can serve as a crucial piece of evidence. Witnesses can be invited to testify about the use of the trademark in question and their witnessing of the infringement. Witness testimony can, to a certain extent, confirm the authenticity of the case and provide more details.
Expert appraisal report
Sometimes, experts are needed to conduct appraisals and assessments of trademark similarity, market impact, and other aspects. Expert appraisal reports can provide authoritative opinions and professional analysis, helping the court better understand the technical details and professional issues of the case.
Online survey results
In today's digital age, online investigations are also a crucial component of overseas service trademark infringement investigations. Investigators need to review the usage of the trademark in question on major social media and e-commerce platforms, as well as consumer evaluation and awareness of the trademark. Online investigations can further confirm the extent of the infringement.
