Xiaomi provided evidence to clarify:
The keel hinge and the double spin drop hinge are completely different:The double-rotating waterdrop hinge adopts the design scheme of "2-level rod group, 3 components and 4 low pairs", while the mechanical structure of Xiaomi's self-developed keel hinge adopts an innovative "3-level rod group, 5 components and 7 low pairs" design.

Regarding netizens' questions about the difference between level 2 and level 3, Xiaomi also gave an answer:Huawei also applied for a Level 3 patent in October 2021, indicating that Level 2 and Level 3 are not the same thing. Judging from the patent application and publication date, Xiaomi has also proved that it is the first.
Regarding plagiarism, Xiaomi gives evidence:The double rotary hinge was patented in 2019 and disclosed in 2021. Xiaomi keel hinge 2020 application, the filing date is earlier than the publication date, and Xiaomi added that the patent is not disclosed is confidential.
Regarding the invention patent applied by Huawei, the utility model patent applied by Xiaomi:The patent drawing shows that the Xiaomi keel hinge patent is a double application, applying for a utility model patent and also applying for an invention patent. The utility model patent is granted faster, and rights can be protected as soon as possible, and the keel hinge utility model patent application will be disclosed 3 months after the application, and the invention patent will be disclosed in March 2022.

In addition, whether intentionally or unintentionally, this kind of hand-to-hand and step-on does affect unity.
