If Alibaba stores are sued for trademark infringement, the stores should actively take the following measures:

Confirm whether the defendant is the legal right holder.

Collect evidence to prove that you have not infringed.

If it is determined that the infringement has been established, you should negotiate with the other party as soon as possible to resolve the issue and take the initiative to assume the corresponding compensation liability.

If the negotiation fails, you can file a lawsuit in court to demand that the infringement be stopped and compensation for losses be paid.

During the litigation process, you should provide as much detailed evidence as possible on the facts of infringement, sales volume, sales volume, etc. to increase your chances of winning.

If you have received a subpoena, you should take the trial procedure seriously and fully state your opinions and reasons in court.

In short, in the face of trademark infringement issues, Alibaba stores should take proactive measures to try their best to safeguard their legitimate rights and interests while avoiding further losses.
