On July 22, 2020, the CNIPA issued No. 45428 invalidation decision, declaring that the invention patents entitled "Neck Massager" owned by Guangdong Aishikaiqi Intelligent Technology Co., Ltd. were all valid.

After accepting the client's entrustment, the team of Hengbo carried out a lot of meticulous preparatory work, including successfully pointing out the other party’s evidence flaws and technical understanding errors. In the end, the CNIPA decided to maintain the patent rights in full.

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