Rules for Product Compliance:

Depending on the IPR claim listed on the Appeal page, you will need to send the supporting documents.
Here are some examples of supporting papers for IPR appeals:
  Following are the types of evidence necessary for appeals (choose one to submit).
This screenshot shows an order I placed on BuyStockLot that predates the complainant's copyright publication/patent application.
Snapshot of the Order
If you are ordering through BuyStockLot, you should provide a screenshot of your order details so that BuyStockLot can verify your order. As the information cannot be verified, proof of transactions from other websites is not accepted. Therefore, it is necessary to take a snapshot of the transaction, including the website address, the order number, the transaction time, and details about the buyer and the brand. (The product depicted in the transaction record must match the images, technical specifications, artistic works pictured in the claim document.)
Orders must be received before the complainant's copyright publication/patent application.
As long as the order was placed on the BuyStockLot platform, it does not have to be the sales record of the store that received the claim.
The product was publicly posted before the complainant filed a patent application.
Publication evidence
Copyrighted works published on SINA or in newspapers, journals, books.
An image of a website snapshot must include a link to the website.
It must be earlier than the complainant's copyright publication/patent application date.
I have proof that I obtained the I.P. before the complaint was filed.
Please submit your copyright certificate and the copyright registration page if you are claiming infringement. Your certificate's registration date must be earlier than the complainant's copyright publication date.
Please send your patent certificate if you received a patent infringement claim. Your certificate application date must be earlier than the complainant's patent application date, and your patent information must match the details of the product that was the subject of the claim.
Authorization for the original image/photo (applies to claims concerning illegally copied website images)
Authentic images
Original photos must not be too small. You can post images up to 5M in size on the appeal page.
"Original pictures" refer to photographs that have been exported directly from a camera, cellphone, or another device without editing.
Image usage authorization:
Validation from the rightful owner/complainant.
The use of images/text must be explicitly stated in the authorization form.
The permission document must bear the official seal of the owner of the intellectual property right.
It is essential to understand the difference between authorization for sales and authorization for picture use. Copyright issues regarding unlawfully reproduced website pictures are involved here and have nothing to do with sales authorization.
Evidence of differentiation
Patent for utility model/invention: Demonstration of distinction
Analysis of utility model/invention claims as they relate to those of the product that is claimed.
Patented designs: Proof of distinction
Comparing the complainant's product photos (6 sides) with the claimant's (6 sides).
Copyrighted work: A demonstration of merit
Comparison of the protected work with the goods for which the claim was made.
You should keep in mind that the information on appeal claims is provided for your convenience only. Depending on the circumstances, the proof needed for appeals varies in practice.
Source of legal procurement

The term "legal procurement source" refers to proof of purchase or permission that can demonstrate your items were acquired legally. Depending on your procurement sources, you can pick which proof to present.
Authorization documentation:
Complete authorization connection (e.g., IPR owner B.C. supplier).
In the proof of authorization, every step of approval from the IPR owner to the shop owner must be documented.
Valid proof of authorization must have been on file before the claim date.
Permission must be verified by giving details about the relevant product, including the brand name, model number.
The official seal of t
he authorizer must accompany the authorization.
Purchase receipt/invoice:
Complete purchasing chain (e.g., IPR owner B.C. supplier)
Each purchase step must be documented on the proof of purchase from the IPR owner to the store owner.
Proof of purchase/invoice must include the following details: corresponding brand name, model number, other product information, quantity ordered (must match the number of items sold), price, date of purchase (must predate claim), purchaser, the seller.
Proof of purchase must bear the seal of the seller, seal of sale.
You must provide evidence that your activity occurred before the complainant's intellectual property right was formed (applies to IPR claims concerning improper use of copyright, invention patent, design patent, or utility model patent of others)
