Attorney: Ye Xiujin



Guangdong Zhigao Air Conditioning Co., Ltd. and Zhuhai Gree Electric Appliance Co., Ltd. have a patent invalidation dispute. Desai Intellectual Property Agency has been entrusted to request invalidation of 5 patent applications from Zhuhai Gree Electric Appliance Co., Ltd., including 3 utility models and 2 invention patents. Desai intellectual property requested the China National Intellectual Property Administration to declare all patents involved invalid on the grounds that the patent claims involved do not possess novelty and creativity compared with the existing technology.



After examination, the China National Intellectual Property Administration found that two patents were invalid, two patents were maintained, and one patent was withdrawn due to the settlement reached by both parties.



This case, through the application for invalidation of the patent, provided the client and patentee with negotiation opportunities in technology and market competition, and won valuable development opportunities for both parties to peacefully coexist for a certain period of time, successfully achieving the purpose of the commission.
