On May 25, 2018, the Hengbo team accepted the client's entrustment and conducted a large number of searches on prior arts related to the above patent. It was found that there were prior arts in the patent literature that are similar to the patent involved. On this basis, a request for invalidation was filed. After five months of trial, CNIPA finally made a decision to declare the patent in entirety invalid.
