Recently, Junzhiquan won the first instance of the administrative lawsuit of the diaphragm patent case of Xinwei Company.
In 2020, Xinwei filed a request for invalidation for the first time after being sued for a diaphragm patent, but after administrative litigation procedures, the patent was maintained as valid.

In 2024, Junzhiquan will act as an agent for Xinwei Company to initiate an invalidation request again, and through in-depth technical analysis and precise legal argumentation, the patent involved in the case will be declared "all invalid" due to lack of inventiveness. In 2025, the other party filed an administrative lawsuit and submitted more than 20 pieces of evidence, and the Junzhiquan team responded accurately with its professional ability, and finally won the first instance of the administrative lawsuit.
