If you have infringement, but you don't handle it within the time limit required by the complaint, the other party may take further measures, and Taobao may also take corresponding measures, such as compulsory removal.
On the other hand, if you have a legitimate reason that there is no infringement, submit relevant materials at the time required by the complaint, including the authorization certificate of relevant intellectual property rights or the reasonable source of the goods, and Taobao will make corresponding judgments after submission.
