are among the best among similar products on the Amazon platform. The time point of this complaint is on the eve of the "Black Friday" promotion. If the response is improper, the complained products cannot be restored before Black Friday, which will cause heavy losses to the seller.

2. Difficulties of the case

#1 Time is running out -

"Black Friday" is coming, and if cross-border e-commerce sellers miss it, their profits will be greatly affected.

The "Black Friday" of cross-border e-commerce is similar to the "Double Eleven" event of domestic e-commerce. On the Friday after the fourth Thursday of November (Thanksgiving) every year, German e-commerce and physical stores will focus on discounting products.

Against the backdrop of the general trend of the global economy, the cross-border e-commerce industry is growing in scale. "Black Friday" has developed into a global online sales season, and it is the best opportunity for cross-border e-commerce sellers to increase sales. Therefore, it is particularly important for sellers to re-list links to relevant products on Amazon Germany before Black Friday.

#2 On the premise of sufficient evidence, the first round of appeals was rejected.

Time is tight, and the speed of submitting appeal materials is crucial. In order to submit the complaint materials as quickly as possible and restore the link to the complained product as soon as possible, our firm combined the relevant information provided by the seller, brainstormed and expedited the preparation of the complaint documents. Relevant information can prove that the complained product has been sold on Amazon's US site as early as 2019, and the priority date of the 083 patent is August 24, 2020. Obviously, the product under complaint is produced and sold first, followed by the application for the 083 patent.

△ Time when the complained product was put on the Amazon US site

In order to further improve the success rate of the appeal, in addition to providing the above sales evidence in the appeal materials, we also submitted more other prior use evidence to Amazon through in-depth communication with the seller to fully prove the seller's prior use. Unfortunately, Amazon believes that the evidence in the complaint materials is still not enough for it to restore the link and put the product on the shelves, and the appeal work has reached a deadlock.

Complaints from multiple angles, flexible response to challenges

After the failure of the first round of appeals, we adopted a serious and responsible attitude and thought from multiple angles, learned from the experience of the first round of appeals, changed the thinking dimension, and started from different angles to immediately carry out comparative analysis of patent infringement. Based on the results of the comparative analysis of patent infringement, we appealed again on the grounds of non-infringement, striving to stop losses for customers in a timely manner.
