When our trademark is "revoked" by others, we have to produce evidence of trademark use to prove that we have not used the registered trademark for three consecutive years. The evidence materials for trademark use must be well prepared, and the more detailed the materials are, the greater the possibility of maintaining and retaining our exclusive right to use trademarks.

how to collect evidence of trademark use?

so what data materials can be used as evidence of the use of our trademark?

1. Invoice: A true and valid invoice for the sale of goods or the provision of services can strongly prove the use of registered trademarks. Therefore, enterprises should pay attention to fill in the name of goods or services completely when issuing invoices, avoid writing only abbreviations, and keep invoices well.

2. contracts: contracts and agreements are important evidence and basis for economic entities to participate in economic activities, so they can be used as effective evidence for trademark use. The registered trademark must be clearly marked when the contract is drawn up and signed. The safest thing is to write the name and registration number of the fully registered trademark.

3. Advertising articles: The advertisements in newspapers, magazines, conferences, expositions, trade fairs, etc. are direct and powerful evidence because they can provide important information such as time and trademark identification. However, the advertising contract signed with the advertising company can be used as evidence of effective use as long as the trademark name is identified in the contract.

4. packaging: documents such as the contract signed with the printing factory when printing is entrusted can be issued as evidence of effective use, and the contract should be marked with the trademark name.

5. product inspection report: the product inspection report issued by the superior quality supervision department, trade association and other authoritative institutions to prove the quality of the goods, with strict procedures and clear labels on the contents of the report, is a good trademark use evidence.

there are other materials that can be used as evidence of the effective use of trademarks, such as trademark printing certification materials, product specifications, commodity entry and exit inspection and quarantine certificates, product declaration forms, etc. If we can master a variety of evidences, we can reach an effective evidence chain that confirms the correlation between evidences and greatly increase the effectiveness of trademark materials.
