As long as the legal source of the suspected infringing product can be proved, it will not be liable for compensation. You can prepare evidence from the following aspects:
1. The names of Alibaba merchants to be supplied are clear;
2. The other party sues that you must have bought the product from your Taobao link. You need to find the corresponding order, and find out the order you placed from Alibaba (including order number, purchased products, payment information and logistics information), which is consistent with the order purchased by the other party;
3. Immediately delete the link of the suspected infringing product.
