Xu Peicheng (Hong Kong) Optoelectronic Technology Co., Limited

I'll research this company before writing the profile.

Let me dig deeper into the real party in interest and the underlying dispute.

Xu Peicheng (Hong Kong) Optoelectronic Technology Co., Limited (Chinese: 旭佩成（香港）光電科技有限公司) is a private Hong Kong company limited by shares, incorporated 10 January 2023 (BRN 74763296, CR No. 3224075), with its registered office at Unit 1507C, 15/F, Eastcore, 398 Kwun Tong Road, Kwun Tong, Kowloon. It is not publicly traded. No employee count, revenue, or funding data is published in any source I could verify. Hong Kong registry records list no parent, but in its PTAB filings the company names Shenzhen Yuyixin Lighting Technology Co., Ltd. as a co-real party in interest, indicating affiliation with that mainland Chinese lighting business. Its incorporation date and registered address are consistent with a special-purpose vehicle rather than an established manufacturer.

Products / operations. No product catalogue, company website, or trade presence for the Hong Kong entity could be verified. Its only documented activity is U.S. patent-office litigation. The technology at issue — LED curtain lamps and their driving/control apparatus — points to decorative LED lighting as the underlying commercial activity, likely conducted through the affiliated Shenzhen entity. On the available evidence it should be treated as an IP-holding/defensive vehicle, not a verifiable operating company.

Litigation posture. The tracked data show 1 PTAB case as "plaintiff" and 0 as defendant — but the plaintiff label reflects petitioner status in inter partes review, not district-court infringement claims. This is a defensive invalidity posture, not NPE assertion: Xu Peicheng is attacking patents owned by Semisilicon Technology Corp., a patent owner that itself actively sues Chinese sellers of LED products (e.g., Semisilicon v. Changzhou Jutai Electronic, N.D. Cal. 4:25-cv-02665; Semisilicon v. Huzhou Xinju Electronic Commerce, E.D. Tex. 4:26-cv-00979). No district-court case naming Xu Peicheng appears in the tracked data.

Notable cases. Xu Peicheng (Hong Kong) Optoelectronic Technology Co., Limited v. Semisilicon Technology Corp., IPR2024-00156, filed 8 November 2023, challenged U.S. Patent 8,884,546 ("Driving Apparatus for Light-Emitting Diode Curtain Lamp"); the Board instituted review on 20 May 2024 and entered a final written decision on 14 May 2025. A companion petition, IPR2024-00157, challenged U.S. Patent 8,124,988; institution was denied on 20 May 2024, rehearing denied 16 September 2024, and post-institution fees refunded. Counsel recorded: Rimon P.C. (petitioner) and Finnegan (patent owner). The same-day filings suggest a coordinated defensive strategy on behalf of an LED lighting seller.
