Recently, a patent invalidation case involving the home appliance industry that Zhifan IP Attorneys represented has concluded. China National Intellectual Property Administration issued the examination decision No. 5W135406 on request for invalidation, declaring that the patent with the number “202220721859.1” and titled “Bathroom Master Having Circular Airflow” is entirely invalid. This outcome will lead to the forced termination of the first-instance litigation by the patentee (plaintiff).

After relentless efforts, Zhifan IP Attorneys successfully invalidated the entire patent.
