2021, Zhejiang Suote also announced a settlement in August 2022 after a year of pulling with the above two patents (ZL 201180032359.1 number and ZL201180032701). According to the
data, the above patents were issued by Zhejiang Soter in February 2021, and in September 2025, Dike shares were analyzed by
industry insiders. Dike shares launched intensive patent litigation, or the "blood return" self-help under the pressure of the main business profits. According to the 2025 financial report

In order to cope with the risk of price fluctuation of silver powder, the Company conducted hedging operations through silver futures contracts and silver leasing business. However, in the current period, silver futures rose rapidly and sharply, and the amount of loss from changes in fair value of silver futures and silver leasing on the balance sheet date was relatively large .
In this context, if the above-mentioned patent lawsuit with a total claim of up to 800 million yuan is finally won, it is expected to greatly improve the current financial situation of Dike shares and become an important "blood return" channel to ease its performance pressure .
