All the products we sell on Taobao are fakes, so we complained. As a result, the other party provided false authorization and passed. What should I do? trouble

Your problem is very serious. Liars infringe on your rights and sell fakes. You must contact Taobao human service to verify. If Taobao's human customer service can't handle it, it must take legal weapons to protect its products. If the patented product is infringed, it is suggested to find a professional lawyer offline, and you can sue or send a lawyer's letter to give a warning to stop its infringement or economic compensation.
