YiJu and Sunshine IP jointly represented the patentee Gree Electric Appliances Inc. of Zhuhai in successfully closing a utility model patent invalidation case. The State Intellectual Property Office issued Examination Decision No.52493, upholding that the utility model patent owned by Gree Electric Appliances, "Connection structure and electrical device comprising same" (ZL201821569102.5) was valid in its entirety.
As the agents of the patentee, we analyzed the evidence provided by the petitioner, as well as the claims of the patent in question word for word and sentence for sentence and located each and all the distinctions, and made an effective defense mainly on the ground that the technical scheme of the patent in question adopts different components to "match to form an inner groove structure", while the evidence does not involve such "match", as supplemented by other distinctions, and eventually obtained the approval of the collegial panel, upholding that the patent right in the patent in question was valid.
