SMM survey: what kind of metal do you like most in 2022?
Today, Jiangsu Changdian Technology Co., Ltd. (hereinafter referred to as "Changdian Technology") announced that it launched a series of legal actions against the infringement and unfair competition of Yong Si Electronics (Ningbo) Co., Ltd. (hereinafter referred to as "Yong Si Electronics").
Specifically, the demand of Changdian Technology is mainly divided into two parts:
On the one hand, some Yong Si Electronics employees hold Yongsi Electronics shares during the tenure of Changdian Technology, that is, through the way of others' holding. This move violates the conflict of interest policy of Changdian Technology and the basic integrity and loyalty obligations of employees, against which the company has filed labor arbitration and litigation.
On the other hand, Yongsi Electronics has a total of 38 patent inventors, of which 32 have worked in Changdian Technology, accounting for more than 80%. Changdian Science and Technology believes that Yongsi Electronics has patent instability, derived from patents or proprietary technology owned by Changdian Technology.
In view of some of the invention patents authorized by Yongsi Electronics, Changdian Technology initiated a request for invalidation to the patent administration department; in response to the above-mentioned actions and legal consequences of Yongsi Electronics and some managers and core technical personnel, Changdian Technology has reported and complained to the relevant regulatory authorities, including the Securities Regulatory Commission.
From the main business point of view, both are semiconductor IC closed test manufacturers.
Changdian Technology is the leader of closed testing in China. According to the data, 85% of the top 20 semiconductor manufacturers in the country are their customers, and the company's overseas revenue accounted for more than 70% last year. At the close of trading today, the company's share price closed at 31.27 yuan per share, up 1.13%.
Yongsi Electronics is a four-year-old "newcomer" in the industry, and the company has established cooperative relations with Hengxuan Technology, Jingchen shares, MediaTek, Beijing Junzheng, Weir shares and so on. The company is currently in the process of applying for Science and Technology Innovation Board IPO and replied to the second round of inquiries on the 17th of last month. In the prospectus, Yongsi Electronics listed Changdian Technology, Huatian Technology and Tongfu Micropower as domestic comparable companies.

It is worth noting that Yongsi Electronics has achieved stable mass production after it was established for more than half a year. In addition, in 2018, the company's main R & D projects did not involve FC products, but the company achieved 31.7051 million yuan in revenue that year.
The Shanghai Stock Exchange sent an inquiry to the company in this regard. Yongsi Electronics replied that the company has carried out relatively full research and development and technical demonstration before mass production, and the product technology is obtained by independent research and development. The company's management team has rich experience in the IC closed test industry, laying the foundation for faster stable mass production; at the same time, the company's closed test plant is acquired by outsourcing, which also greatly shortens the construction cycle.
In terms of performance, in the first half of this year, Yongsi Electronics achieved a year-on-year increase of 240.09% in revenue and 58.57% in production capacity, with a gross profit margin of 30.22% over the same period.
