On June 25, 2023, the China National Intellectual Property Administration issued the Invalidation Decision No. 562020, announcing all patent rights owned by APEX BEAM TECHNOLOGIES LLC, named "A Method And Device For Wireless Communication In A Base Station And User Equipment" were invalided.

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

It is decided that: if there are distinguishing features between the technical solution claimed in the claims and the closest prior art, but the distinguishing features belong to the usual means in the technical field, and those skilled in the art can clearly obtain the technical solution claimed in the claim based on the combination of the aforementioned prior art, then 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.
