On October 21, 2024, the China National Intellectual Property Administration issued Invalidation Decision No. 582348, declaring that the patent rights of Guangzhou Stars Pulse Co.,Ltd. entitled " A Electric Toothbrush Head " remains valid.

After accepting the client's commission, the Hengbo team conducted a lot of meticulous preparation work, including successfully pointing out the flaws in the other party's evidence and technical misunderstandings. Ultimately, the State Intellectual Property Office decided to maintain the validity of the patent right.

The decision holds that: due to the certain privacy of files collected on WeChat, the public cannot know them whenever they want, so it is impossible to determine the time when files collected on WeChat will be made public.

According to the law, if the patent owner is dissatisfied with the invalidation decision, he or she may file an administrative lawsuit with the Beijing Intellectual Property Court within three months.
