However, Li Qiumin invests in a company that overlaps with the Quanquan Optoelectronics business and serves as a director of the company.

3.3 Li Qiumin or investing in Aung Saiwei abroad, and both parties are integrated circuit design enterprises and the application fields may be stacked.

According to the data of the Market Supervision and Administration Bureau, Shanghai Yisili Electronic Technology Partnership (Limited Partnership) (hereinafter referred to as "Shanghai Yisili") was established on January 17, 2017. The business scope is technology development, transfer and consultation in the field of electronic technology Wait.

On March 22, 2017, investors invested in Shanghai Yisili changed. Before and after the change, "Li Qiumin" was one of the shareholders of Shanghai Yisili. On the same day, the proportion of capital contribution in Shanghai Yisili changed, and "Li Qiumin" changed its shareholding ratio of Shanghai Yisili from 90%to 66.67%. On May 13, 2020, the proportion of capital contributions in Shanghai Yisili changed, and the shareholding ratio of "Li Qiumin" changed from 66.67%to 81.82%. As of August 3, 2022, Shanghai Yisili had no other investors and investment proportion of "Li Qiumin".

It can be seen that from January 17, 2017 to August 3, 2022, "Li Qiumin" was the controlling shareholder of Shanghai Yicine, or the actual controller.

On the other hand, Shanghai Yisili controlled by "Li Qiumin", a company invested in the business or overlap of Quanquan Optoelectronics.

According to data from the Market Supervision and Administration Bureau, Ang Sai Microelectronics (Shanghai) Co., Ltd. (hereinafter referred to as "Ang Saiwei") was established on February 5, 2015, with a registered capital of 5.699 million yuan. Internal technology development.

As of August 3, 2022, Shanghai Yisili was one of the shareholders of Angsili. Since February 16, 2017, Shanghai Yisine has been one of the shareholders of Ang Saiwei. From July 15, 2015 to February 15, 2017, "Li Qiumin" is one of Ang Saiwei's shareholders. And from July 13, 2020 to August 3, 2022, "Li Qiumin" all served as Aon Saiwei's director.

According to the research of the Northern Capital Center of "Golden Syllabus", as of August 3, 2022, Shanghai Yisili's shareholding ratio of Angsiwei was 10.27%. Yisili's indirect shareholding of Ang Sai was 8.4%.

According to public information, according to public information, Shanghai Yici's actual controller "Li Qiumin" and Ang Saiwei director "Li Qiumin" also held the equity of Hai Chun Investment.

That is, "Li Qiumin" of Shanghai Yici, "Li Qiumin", the director of Ang Saiwei, or Li Qiumin, the director of the design director of the R & D department of the Quanquan Optoelectronics Technology Technology, is the same person.

According to the official website of Ang Sai, as of August 3, 2022, Ang Saiwei is an integrated circuit design enterprise with a magnetic sensor, high -performance simulation and hybrid signal. Wearable devices, smart homes and the Internet of Things, and intelligent monitoring security systems.

And Ang Sai Microelectronics uses high -performance deep sub -micron CMOS, dual -pole, BCD and other process technologies to combine its own patents to develop proprietary integrated circuit products, with magnetic sensors, smart terminals and intelligent wearable devices, smart home and smart home and smart home and smart home and smart home and smart home and smart home The Internet of Things, intelligent monitoring security systems, industrial control and automotive electronics are targeted.

In addition, the integrated circuit of Angsai Microelectronics focuses on solving the challenges in system equipment design. Products include magnetic sensors, switch chargers, LED drivers, DC-DC, LED intelligent lighting, speed and motion sensor, industrial control and automotive electronics Wait.

In addition, Ang Saiwei recruits the work responsibilities of simulation IC design engineers, including responsible for simulating the definition, development and verification of simulation of integrated circuit chips; cooperate with the marketing department to complete the initial definition of the project, lead the technical feasibility study and establishment of projects; The specific circuit architecture leads the project team members to complete the simulation circuit design, simulation, and verification work; the planning layout layout, guiding and assisting Layout engineers to complete the layout design to ensure that the layout meets the requirements of the circuit design, etc.

According to data from the State Intellectual Property Office, the patent number of 2021207569907 is a practical new patent "melting correction circuit". The application date is April 14, 2021, and the authorization date is April 8, 2022. As of August 3, 2022, the case status was maintained by patent rights. The inventor was Xiangchen, Zhang Liang, and Peng Qingsong, and the applicant was Ang Saiwei. The patent belongs to the field of electronic circuits and involves a kind of repair circuit.

It can be seen that Li Qiumin, the director of the technology research and development department of Jiquan Optoelectronics, or indirectly holds Angosai's 8.4%of the shares and serves as a director. In addition, Sai Angwei, as an integrated circuit design enterprise, is also a Spring Optoelectronics, which is also an integrated circuit design enterprise. The application areas of the main products include smart homes and smart lighting. Not only that, in the recruitment information of Quanquan Optoelectronics and Ang Saiwei, the applicants have chip test quality, and both companies are now involved in the patent of the electronic circuit field.

In other words, Li Qiumin, the director of the layout design of Yiquan Optoelectronics, is also an inventor of a core technology patent of Huanquan Optoelectronics. Or overlap. In this regard, can Li Qiumin, the engineer of the layout design, can perform his duties independently? Does the Quanquan Optoelectronics face the risk of potential technology leakage? Is there a lack of internal control? Or should "get a question mark".

The embankment of thousands of miles broke the ant hole. Focusing on the doubts of Quanquan Optoelectronics, will the truth of the capital market emerge in the future?
