Taobao appearance patent infringement case

If you only sell, and you can provide proof of sale that you don't know that the product is a patented product, you have stopped selling immediately after receiving the notice. Then, although you have infringed, the patent law stipulates that in this case, the patentee cannot claim compensation from you, and it is not necessary to provide proof of sales before the filing date.

Article 70 of the Patent Law: Anyone who uses, promises to sell or sells an infringing patented product for the purpose of production and operation without knowing that the product was manufactured or sold without the permission of the patentee shall not be liable for compensation.

No proof of sales is required before the application date. Even if he authorizes you to start selling, as long as you can prove that the source of the product is legal, it is infringement, but there is no compensation.
