On March 31, 2022, the CNIPA issued an Invalidation Decision No. 54917 and declared that all rights of the patent entitled a RRC-state control method, device, and a computer storage medium, which is owned by OPPO Guangdong Mobile Communication Co., LTD were valid.

After accepting the client's entrustment, Hengbo has made a lot of efforts and successfully pointed out the defects of evidence provided by the other party and their misunderstanding for technology. Finally, the CNIPA decided to mention the patent rights invloved valid.

According to the law, if the claimant disagrees with the invalidation decision, he or she can file an administrative litigation to the Beijing Intellectual Property Court within 3 months.
