On March 28, 2023, the China National Intellectual Property Administration issued the Invalidation Decision No. 560757, announcing that all the patent rights owned by Guangdong EBELONG Technology Co., Ltd., entitled"Self-Generating Wireless Switch And Its Application" were invalid.

After accepting the client's entrustment, the Hengbo team conducted a lot of arduous searches, and finally successfully invalidated the patent.

The decision considers that : if the technical solution claimed by a claim has distinguishing technical features relative to the closest prior art, but a part of the distinguishing technical features is disclosed by other prior art and provides technical inspiration for combining them with the closest prior art and the rest belong to the common knowledge in the field, the claim does not involve an inventive step.

According to the law, if the patentee refuses to accept the invalidation decision, he can file an administrative lawsuit with the Beijing Intellectual Property Court within three months.
