In mid-March 2026, Shanghai Fourier Semiconductor Corporation's listing process on the Hong Kong Stock Exchange encountered a sudden obstacle. Just as the company had passed the exchange's listing hearing and was on the verge of entering the capital market, domestic analog chip competitor Awinic Technology filed a lawsuit against it, alleging infringement of invention patent rights.
According to a court hearing notice disclosed by Tianyancha, the case is scheduled to commence trial at the Shanghai Intellectual Property Court on April 27, 2026. This timing coincides precisely with the sensitive window period of Fourier Semiconductor's final push for its Hong Kong IPO, casting a significant shadow over the listing process.
The lawsuit emerged shortly after Fourier Semiconductor passed its listing hearing on March 15, 2026. The company had previously obtained overseas listing filing approval from the China Securities Regulatory Commission, and its path to listing had appeared smooth. Public information shows that this perception intelligence chip provider, founded in 2016, has core businesses covering automotive smart audio chips, medium- to high-power smart audio chips, and portable smart audio chips. Its client portfolio includes well-known brands such as Samsung,
However, soon after the hearing result was announced, Shanghai Awinic Technology Co., Ltd. sued Fourier Semiconductor at the Shanghai Intellectual Property Court. Case information numbered (2025) Hu 73 Zhi Min Chu No. 195 indicates the trial will begin at 9:00 AM on April 27, 2026. For Fourier Semiconductor, this timing is particularly sensitive. Typically, after passing the hearing and before the official listing, the issuer and underwriters must complete a series of critical tasks including roadshows, pricing, and share placement. A major intellectual property lawsuit at this stage could directly impact investor confidence.
According to Fourier Semiconductor's prospectus submitted to the Hong Kong Exchange, the company has demonstrated rapid revenue growth in recent years, but continues to face profitability challenges. Data shows the company's revenue for 2022, 2023, and 2024 was 130 million yuan, 150 million yuan, and 355 million yuan respectively, indicating a significant compound annual growth rate. However, the company reported net losses of 65.9 million yuan, 94.13 million yuan, and 56.84 million yuan for the same periods.
In the first ten months of 2025, the company achieved revenue of 281 million yuan, with a gross profit of 56.06 million yuan. The gross margin improved to 20%, but the company still recorded an annual loss of 51.78 million yuan. In terms of revenue structure, adaptive power control audio chips accounted for 51.6% of revenue, while portable amplifier audio chips accounted for 39.3%, forming the two core business pillars.
Notably, as of October 31, 2025, the company held cash and cash equivalents of 73.46 million yuan. Given the persistent losses and limited cash flow, the IPO is critically important for providing necessary capital infusion.
The plaintiff,
Financially, Awinic reported revenue of 2.176 billion yuan for the period from January to September 2025, with net profit attributable to shareholders of 276 million yuan, a year-on-year increase of 54.98%. As an established listed company, Awinic holds considerable advantages in both capital strength and technological accumulation. This patent lawsuit undoubtedly presents substantial pressure on Fourier Semiconductor's IPO process.
In the semiconductor industry, facing patent lawsuits from competitors just before an IPO is not uncommon. In recent years, as competition in the domestic chip design sector has intensified, patent litigation has become a frequent tactic to disrupt a rival's listing plans. For a company seeking to go public, a confirmed infringement could lead to direct consequences like product sales bans and financial compensation, severely impacting investor valuation assessments.
The cause of this lawsuit is a dispute over invention patent infringement. Compared to utility model or design patents, invention patents generally involve higher technical substance and greater legal stability. A ruling in favor of the plaintiff could be particularly damaging for the defendant. The court notice confirms the trial date of April 27, at which point the focal points of the dispute, the specifics of the patent in question, and whether Fourier Semiconductor constitutes infringement will become the market's primary focus.
For Fourier Semiconductor, which has already passed its hearing, the direct impact of this lawsuit is increased uncertainty surrounding its listing. According to Hong Kong Exchange listing rules, issuers must fully disclose significant litigation risks in their prospectuses. Investors will also factor potential intellectual property disputes into their valuation considerations.
Some market analysts suggest that Fourier Semiconductor can choose to actively defend the lawsuit, seek a settlement, or attempt to invalidate the patent. However, resolving the dispute within the tight IPO window is challenging, and the company may need to adjust its listing timeline. Furthermore, if the court ultimately rules that infringement occurred, the company could face penalties including a ban on sales of the relevant products. This would directly impact Fourier Semiconductor, whose core revenue relies heavily on audio chips.
As of the time of writing, Fourier Semiconductor has not issued an official response regarding the lawsuit. In the wave of domestic substitution for analog chips, the contest of technological prowess has extended from the laboratory to the courtroom. The outcome of this litigation will significantly shape the future of this emerging domestic audio chip company.
