From what you asked, it seems that you have some knowledge about trademarks.

Let’s make a bold guess. The trademark rejection, objection, or invalidity you may encounter is most likely due to the cancellation of a trademark that has not been used for three years (withdrawal three), and you want to prove the actual use through actual use. .

If you only submit supporting materials to the Trademark Office instead of the court:

Category 1-2.35 can be proved through photos, magazines, advertisements, and online. Currently, the more effective one is Baidu's photo deposit (But it must be notarized) to prove;

3. Advertising is mainly to ensure the integrity of your trademark appearing in advertisements. You cannot use the R mark without obtaining the trademark registration certificate;< /p>

4-5. It is best if the contract submitted to the court can be notarized. The Trademark Office generally does not pay attention to the contract;

6. For other more powerful evidence, we recommend you to invoice.

Hope this helps.
