Recently, the China National Intellectual Property Administration issued the No. 600422 Decision on Examination of Request for Invalidation. In response to the request for invalidation of the invention patent (patent number: 202210288202.5) held by our company (Xiamen Jinruiyi Industry and Trade Co., Ltd.) by Wuxi * * * * Refrigeration Technology Co., Ltd., the China National Intellectual Property Administration finally decided to maintain the validity of the patent right!

The core of this victory lies in our company's unique "exhaust structure and exhaust method for a dry ice preparation device".

What is the strength of our hardcore technology at home?

1. Pain point solution: Traditional equipment has difficulty discharging high-pressure carbon dioxide gas remaining in the mold cavity after ice making, resulting in low conversion efficiency.

2. Technological breakthrough: We use a unique exhaust valve design (citing the "distinguishing feature" mentioned in the decision) to exhaust residual gases at the moment of ice making, which not only solves the problem of difficult exhaust of residual gases, but also greatly improves the conversion efficiency of dry ice.

3. Conclusion: This technology has been reviewed and recognized by the China National Intellectual Property Administration as having outstanding substantive characteristics and significant progress, and is not a common knowledge.

Why should we take the road of safeguarding rights seriously?

Some people may ask, why spend a lot of energy, manpower, material resources, and financial resources to fight a patent lawsuit?

1. Internally: This is respect for every R&D personnel who have devoted countless days and nights. Our company always adheres to the principle of "technology based enterprise". We respect every innovation and hope that the industry will flourish and thrive. We also do not tolerate the theft of the fruits of innovation, which is a desecration of knowledge, innovation, and the industry.

2. Externally: In today's increasingly competitive industry, only by protecting core technologies can we continuously provide high-quality products to the market. We hope to maintain a fair competition market order and promote the healthy development of the industry through legal means.

We welcome supervision, but we also welcome cooperation

Facts speak louder than words, strength forges a brand

1. This victory is not only a strong defense of our company's patent rights, but also a recognition of the innovative spirit of "Made in China".

2. We thank the China National Intellectual Property Administration for its protection of technological innovation, as well as the customers for their long-term trust.

3. Fengli always keeps its doors open: we welcome friends from all walks of life to come and exchange technology and negotiate cooperation. For partners who respect intellectual property rights and pursue supply, we are willing to work together to create a better future; Of course, we will resolutely use legal weapons to safeguard our legitimate rights and interests against any infringement of intellectual property rights.
