On January 4, 2022, the CNIPA issued the Invalidation Decision No. 52952, declaring that the patent rights of "a calibration system and its calibration bracket" owned by Shenzhen AUTEL Co., LTD were partially valid.

After accepting the client's entrustment, the team of Hengbo had done a lot of preparatory work, successfully pointing out the defects of evidence provided by the other party and their misunderstanding for technology. Finally, the penal declared in court that the rights of patent remained partially 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.
