Unitree Technology faces a “patent sniper attack” before its IPO, and the “sniper” has sued 20 banks.
A daily chemical company with a registered capital of only 550,000 yuan has launched a patent lawsuit to snipe at Unitree Technology, the leading enterprise in the humanoid robot industry, at a critical moment during its listing counseling. What kind of mystery is hidden behind this asymmetric business battle?
On August 26, 2025, the Hangzhou Intermediate People's Court will hold a hearing for a rather special patent dispute case. The plaintiff is the little - known Hangzhou Luweimei Daily Chemical Co., Ltd., while the defendant is the recently popular humanoid robot enterprise - Hangzhou Unitree Technology Co., Ltd. (hereinafter referred to as "Unitree Technology").
These two seemingly unrelated enterprises have suddenly been tied together by a patent lawsuit. What exactly is the background of Luweimei, which sued Unitree Technology, and Zhou Jianjun behind it?
The litigated patent has been transferred multiple times, and the company under the inventor also has a listing plan
The plaintiff, Hangzhou Luweimei Daily Chemical Co., Ltd., is rather low - key and mysterious.
Business registration information shows that Luweimei was established in June 2005, with Zhou Jianjun as its legal representative. Its registered capital is only 550,000 yuan, and its business scope includes traditional retail businesses such as online food sales, agricultural and sideline products sales, and daily necessities sales. Zhou Jianjun holds 90% of the shares, and Xu Yan holds 10%.
This small enterprise mainly engaged in daily necessities presents a cross - border feature in patent layout - Tianyancha data shows that the company holds two patents. One is the "Electronic Dog" patent applied for in 2016, which was authorized in 2018, and the inventor is Zhou Jianjun. The other is the "Intelligent Simultaneous Conference System" patent applied for in 2023, which is currently in the substantive examination stage, and the inventors are Zhou Jianjun and Zhou Chan.
According to the specification, the "Electronic Dog" invention involves a household intelligent robot device. It mainly solves the technical problems in the existing technology, such as the relatively single function of household robots and the inability to meet people's increasingly diverse needs. It provides an electronic dog that imitates biological pets, can complete multiple monitoring and control functions, and can also cooperate with the owner for entertainment.
The head and neck are equipped with a high - definition camera, a gas sensor, a microphone, and a speaker. The torso is internally installed with a controller unit, a wireless communication unit, a storage unit, and a power supply unit. When users are away from home, they can remotely connect to the electronic dog through a mobile phone or computer to keep track of the situation at home.
This coincides with Unitree Technology's business. However, as of now, there is no record of the company selling any products related to the "Electronic Dog" in public information.
However, if you follow the clues, you will find that this "Electronic Dog" patent has been transferred multiple times in the past six months, and the initial holder was not Luweimei.
Tianyancha shows that this "Electronic Dog" patent was initially held by Zhejiang Jianlin Electronic and Electrical Co., Ltd. (hereinafter referred to as "Jianlin Electrical"). On February 7, 2025, Jianlin Electrical transferred the patent to Hangzhou Lianhao Technology Trading Co., Ltd., and on July 11, Lianhao Technology transferred it to the current Luweimei.

According to the official website of Jianlin Electrical, it is a company that uses electrical technology to research and develop biological intelligent control servo - control bionic robots, uses Internet wireless protocols to connect Internet of Things intelligent devices, and integrates the large platform of the smart city mobile phone data center.
It currently holds multiple patents in various industries. It claims to "own invention patents for subverting traditional industry equipment, invention patents for drones, and two other invention patents! It also has more than 10 software product copyrights." It also has the ambition to list on the stock market and aims to "strive to transfer to the Growth Enterprise Market for listing as soon as possible!"

On the official website, the address of this company is: Room 612, Building C, Meidu Plaza, No. 789, Moganshan Road, Gongshu District, Hangzhou. And the address of Luweimei, which sued Unitree Technology, is: Room 614, Building C, Meidu Plaza, Gongshu District. The two are only one office apart.
Moreover, the legal representatives of both Jianlin Electrical and Luweimei are Zhou Jianjun, who holds 99.5631% and 90% of the shares respectively.
Tianyancha shows that Jianlin Electrical has a total of 122 patent information items, and most of the inventors are Zhou Jianjun. The patents involve the meta - universe, currency payment, invoices, etc., and the industries involved include hospitals, banks, etc.

The lawsuit against Unitree Technology is not the only patent lawsuit Zhou Jianjun is involved in. Tianyancha shows that Jianlin Electrical has a total of 49 judicial cases, and in 90% of them, it is the plaintiff. The most common cause of litigation is disputes over infringement of invention patents, and the defendants are mostly banks.
Further analysis shows that Jianlin Electrical has sued as many as 20 banks, including the China Construction Bank and multiple branches and sub - branches of the China Construction Bank in Hangzhou, Shanghai, and Beijing, such as the Hangzhou West Lake Sub - branch of the China Construction Bank, the Hangzhou Xiaoshan Sub - branch of the China Construction Bank, the Hangzhou High - tech Sub - branch of the China Construction Bank, etc., as well as the Zhejiang Xiaoshan Rural Commercial Bank, the Wenxin Sub - branch of the Hangzhou United Rural Commercial Bank, etc. The reasons for the lawsuits are all disputes over infringement of invention patent rights or disputes over infringement of computer software copyrights.

Moreover, Jianlin Electrical has become the person subject to execution three times this year, and the execution amounts are 66,800 yuan, 15,000 yuan, and 5.132 million yuan respectively. As a result, Zhou Jianjun has been restricted from high - end consumption.

Unitree has been profitable for five consecutive years, and its revenue has exceeded 1 billion yuan
Compared with Jianlin Electrical, the sued Unitree Technology is more well - known.
On the stage of the 2025 CCTV Spring Festival Gala, 16 Unitree H1 humanoid robots wearing Northeast floral jackets performed the program "Yangge BOT", which amazed the audience. The 1.8 - meter - tall and 47 - kilogram H1 is equipped with 22 self - developed joint motors, with a maximum joint torque of 360 Nm. It cooperates with the reinforcement learning algorithm to achieve precise control of complex dance movements and can even adjust the movement rhythm in real - time according to the music rhythm.
The performance on the Spring Festival Gala made Unitree Technology go from obscurity to a top - tier in the technology circle overnight.

Unitree Technology started with quadruped robots in the early days. In 2017, it launched its first quadruped robot, Laikago, and then gradually expanded to humanoid robots. Quadruped robots include models such as Go1, Aliengo, and B2, which are applied in fields such as education, inspection, and rescue. In terms of humanoid robots, there are the H1 that appeared on the Spring Festival Gala and the G1 for the consumer market.
Although it became famous because of the Spring Festival Gala, Unitree Technology's robots are mostly used in fields such as university scientific research, energy, medical care, and fire protection. Tianyancha shows that Tsinghua University, Westlake University, Ningbo University, Zhejiang University, the School of Continuing Education of Zhejiang Vocational University of Mechanical and Electrical Technology, Chongqing University, Shenzhen Technology University, Central South University, etc. are all customers of Unitree Technology.

Against the background of widespread losses in the humanoid robot industry, Unitree Technology's profitability is a "counter - consensus" existence. Founder Wang Xingxing revealed at the 2025 Summer Davos Forum that the company's annual revenue has exceeded 1 billion yuan, and it has maintained a profitable state for five consecutive years since 2020.
Data from the GGII shows that in 2024, the annual sales volume of Unitree Technology's quadruped robots reached 23,700 units, accounting for about 69.75% of the global market share.
The official JD.com flagship store of Unitree Technology shows that the price of the Unitree Technology quadruped robot Go2 is 9,997 yuan. The PRO version with increased navigation and load - carrying capabilities costs 21,900 yuan, and the Go1 costs 16,000 yuan. If calculated at an average price of 45,000 yuan, the revenue from the quadruped robot business alone exceeds 1 billion yuan.

On May 28, Unitree Technology completed a crucial step - the company name was officially changed from "Hangzhou Unitree Technology Co., Ltd." to "Hangzhou Unitree Technology Co., Ltd.", marking the implementation of the joint - stock system reform.
"From the perspective of the listing rhythm, considering the current review cycle, if Unitree Technology has entered the substantive review stage, it is expected to complete the listing process in 6 - 12 months at the earliest. However, the specific time also depends on the company's preparation and the regulatory review progress. Compared with listing in Hong Kong, the Science and Technology Innovation Board of the A - share market can provide a higher valuation level and better liquidity, which is also an important reason for Unitree Technology to choose the Science and Technology Innovation Board. At the same time, the domestic capital market has a higher understanding and recognition of hard - technology enterprises." said Liang Zhenpeng, a senior industrial economic observer.
Lei Jun and Meituan missed the best investment period. Who will be the big winner of the capital feast?
As Unitree Technology's IPO process progresses, its capital map behind the scenes is gradually becoming clear.
Tianyancha shows that since its establishment, Unitree Technology has received a total of 10 rounds of financing.
At the beginning of its establishment in 2016, Unitree Technology's financing path was not smooth. It was not until it received a 2 - million - yuan investment from individual investor Yin Fangming, who held 20% of the shares, that it completed the crucial seed - round investment and managed to start with difficulty. At that time, Yin Fangming was the co - president of the intelligent education companion robot company roobo.
In 2017, Zhang Peng, the founder of GeekPark, specially organized a tea party attended by big names such as Lei Jun, Wang Xing, Zhou Yuan, and Su Hua for Wang Xingxing in the hope of getting financing for Unitree Technology. Unfortunately, among the big names at this tea party, only Variable Capital under GeekPark took the lead in investing in Unitree Technology in 2018. Other investors included AnChuang Technology Investment and Binhe Investment, with He Xiaopeng as the main investor.
In January and May 2020, it completed the Pre
