On December 12, a spokesman for Xiaomi directly named Yu Chengdong, CEO of Huawei Terminal BG, on its official Weibo, saying that he had made false statements and asked him not to discredit his peers.。For a time, millet Huawei's "war of words" attracted many netizens to watch。

The cause of the incident is Yu Chengdong said at an event: "Friends of the business plagiarism said that they do not respect our intellectual property rights, take the past casually make up a name to say their own.。The double-spin water drop hinge directly becomes the keel hinge, and the keel does not exist。"

Although Yu Chengdong did not name the friend who is, but the outside world have speculated that it is millet, because millet in the promotion of its folding phone mentioned that the phone uses a technology called "keel hinge."。

On the occasion of the rumor of the outside world, at noon on December 12, a spokesman for the millet company officially released micro-blog said, "Mr. Yu Chengdong unprovoked for our company 'keel shaft' technology to release false statements, and the facts are seriously inconsistent."。We ask Mr. Yu Chengdong to follow the basic rules of 'science and rigor' and stop smearing his peers and misleading the public.。"

Xiaomi said that the "keel shaft" is a new generation of folding shaft developed by Xiaomi Group, which is the industry's first 3-level rod group structure.。"Whether it is the design idea or the mechanical structure, the 'keel shaft' developed by Xiaomi is completely different from the 'double-spin water drop hinge' claimed by Mr. Yu Chengdong.。"

To this end, Xiaomi also listed the patent information of its "keel hinge," the patent information of "double-spin water drop hinge" and the patent information of Huawei's level 3 rod set.。

Xiaomi believes that the patent for the "double-spin water drop hinge" was filed in 2019 and only made public in June 2021, while the "keel hinge" was patented as early as September 2020, so there is no so-called plagiarism.。

At the same time, in terms of technical characteristics, the three patents are also different.。The "keel shaft" adopts the design of "three-stage rod group, 5 components and 7 low pairs," which is inconsistent with the design of "two-stage rod group, 3 components and 4 low pairs" of "double-spin water drop hinge"。Although Huawei has a three-level rod set patent, it has not yet been productized, and the patent was not made public until May this year.。

After citing the above evidence, a Xiaomi spokesperson determined that Yu Chengdong's alleged plagiarism was not valid.。

But after Xiaomi's well-founded and self-certified remarks came out, the "melon eaters" did not buy it.。One of the main focuses of netizens' attention is the inconsistency between Xiaomi's patents and Huawei's patent types.。

As can be seen from the patent map released by the official Weibo of Xiaomi's spokesperson, the patent type of Xiaomi's "keel shaft" is "utility model."。

The patent types of Huawei's two patents are "invention application" and "authorized invention," both of which are "invention" patent types.。

According to public information, patents are divided into three types: inventions, utility models, and designs.。Among them, the invention refers to the new technical solution proposed for the product, method or its improvement, while the utility model refers to the new technical solution suitable for practical use proposed for the shape, structure or combination of the product.。

It can be seen that among the three patents compared by Xiaomi officials, it is clear that Huawei's two patents have a higher "gold content" than Xiaomi's "keel hinge" patent.。It is precisely because of this, some netizens believe that the existence of "keel shaft" adopted by the "three-level rod group, 5 components 7 low pair" design is from the "double-spin water drop hinge" "two-level rod group, 3 components 4 low pair" on the possibility of improvement.。If this possibility is true, then millet may be suspected of plagiarism。

As of press time, a Xiaomi spokesperson has not responded to netizens' questions, and Huawei and Yu Chengdong have not responded to Xiaomi's clarification.。

It is worth noting that it is not the first time that Xiaomi and Huawei have had a dispute over patents.。

Earlier this year, Huawei filed a complaint with the State Intellectual Property Office of China that Xiaomi infringed four of its patents, including 4G / LTE technology, mobile phone camera and unlocking technology, and so on.。The State Intellectual Property Office also accepted the case.。In April this year, Xiaomi filed an invalidation request for Huawei's four patents.。However, the State Intellectual Property Office announced on September 1 this year that it rejected Xiaomi's "invalidation request" and maintained the validity of Huawei's relevant patent rights.。Then on September 13, Huawei and Xiaomi announced a settlement, the two sides reached a patent cross licensing agreement。
