I'll research this company before writing the profile.
Let me check the litigation context and the plaintiff's profile.
Altenergy Power System USA, Inc. is the U.S. arm of Altenergy Power System Inc., which trades as APsystems. The parent is headquartered in Jiaxing, Zhejiang, China, with regional offices including Austin, Texas (the U.S. entity's principal office), Shanghai, Sydney, Amsterdam, Lyon and Zapopan. APsystems was founded in 2010 and its parent is publicly listed on the Shanghai Stock Exchange STAR Market (stock code 688348, per Wikipedia and company materials, where the listed entity is identified as Yuneng Technology Co., Ltd.). Employee count and revenue for the U.S. subsidiary are not publicly disclosed; Crunchbase lists an estimated 11–50 employee band. Texas records show Altenergy Power Systems USA, Inc. formed in Texas on Oct. 5, 2023, with a Raleigh, NC registered-agent address — apparently a reorganization of an earlier Washington-registered U.S. affiliate (Seattle/Bainbridge Island).
Products / operations. APsystems is an operating manufacturer of module-level power electronics (MLPE) for solar photovoltaics. Its lines include single-, dual- and quad-module microinverters (YC, QS1, DS3, QT2, EZ1, QS2 series), rapid-shutdown devices sold under the APsmart brand, and residential/commercial energy storage and hybrid inverter products (ELS 11.4k PCS, EZHI, AHS series), plus the EMA monitoring platform. It sells through distributors in over 100 countries.
Litigation posture. This is an operating company defending, not an NPE. The structured data show one tracked case, as defendant, and zero as plaintiff. The sole tracked suit is CyboEnergy, Inc. v. Altenergy Power System USA, Inc., No. 6:22-cv-01136 (W.D. Tex., Waco Division, filed Oct. 28, 2022), asserting U.S. Patents 8,786,133 and 9,331,489 on smart/scalable power inverters and solar mini-inverters; plaintiff is represented by Ramey LLP.
Context. Unified Patents characterizes CyboEnergy as an NPE that has asserted the same patents against Sensata, Northern Electric Power, Aptos Solar, Hoymiles, Duracell and Yotta Energy. The W.D. Tex. court granted Altenergy's Rule 12(b)(6) motion to dismiss on Sept. 13, 2023, and Altenergy separately filed IPR petitions (IPR2024-00360, IPR2024-00362) against CyboEnergy's patents — a defensive-only posture.
