The information of buyers in other Taobao stores cannot be queried.
Taobao keeps user information confidential, so if you are not both parties to the transaction, you cannot query the transaction records of the order.
Taobao accounts can only save their own transaction records, and these transaction records are not disclosed to the public.
Therefore, you cannot query the buyer information of other people's Taobao stores.
If the patent is infringed, complain directly to the other party or find Taobao to defend your rights. As long as the evidence is sufficient, the other party will definitely handle it.
