1, invoice

Keep the true and valid invoices, which is strong evidence to prove the use of registered trademarks. But be careful when filling in the invoice, don't just write a trademark abbreviation. Such invoices cannot be used as evidence of trademark use.

2, product inspection report

The product inspection report issued by the superior quality supervision department is rigorous in procedure and clear in content, which is strong evidence to prove the use of the trademark.

Step 3 advertise

Advertising is an important way for enterprises to promote goods or services, and it is also a very important evidence material. As long as the trademark name is indicated in the advertising contract, it can be used as evidence of trademark use.

4. Contract

If the contract is not marked with a trademark, it cannot be used as evidence of the use of the trademark. Therefore, when signing the agreement, we must improve the registered trademark, and it is best to write down the trademark registration number together, leaving effective evidence for the use of the trademark.

5, product packaging

Product packaging is one of the evidences to deal with the cancellation of trademarks, but it is difficult to determine the specific time of trademark use only by packaging, and other evidences are needed to assist. For example, the trademark name and trademark registration number must be marked on the contract signed when printing is entrusted.

Second, through trademark monitoring and prevention.

Doing a good job in trademark monitoring is also one of the ways to safeguard the legitimate rights and interests of trademarks, because trademark owners can keep abreast of the dynamics of trademarks through trademark monitoring. If someone else registers a similar trademark, or there is infringement, the trademark owner can know it at the first time and take countermeasures to prevent the enterprise brand from being infringed by others.

Third, timely trademark renewal.

Although a trademark can be used for a long time, the premise is to renew it in time. The validity of a trademark is only ten years, and it must be renewed within twelve months before its expiration. If the trademark registrant fails to renew the trademark within the specified time, there is no need for others to apply, and the Trademark Office will also cancel the registered trademark.

Therefore, to prevent the trademark from being revoked, we should not only abide by the trademark use norms, but also carry out regular maintenance and update. Moreover, as long as the trademark owner reasonably regulates the use of the trademark and keeps the evidence, the trademark will not be revoked successfully by others. You don't need to provide all the above evidence to use the trademark, as long as you can prove that the trademark has been used commercially.
