I'll research this company before writing the profile.
Let me verify a few more details on the litigation and company size.
Company overview. CyboEnergy, Inc. is a privately held California company headquartered at 2868 Prospect Park Drive, Rancho Cordova, CA. It is a subsidiary/affiliate of CyboSoft, General Cybernation Group, Inc., a control-technology firm founded in 1994; CyboEnergy was formed to apply CyboSoft's Model-Free Adaptive (MFA) control technology to renewable energy. It is not publicly traded, so no ticker or market cap exists. No company-confirmed headcount or revenue figures are available; third-party aggregator Kona Equity estimates roughly 24 employees and ~$5.7M annual revenue, but these are unverified estimates. Its CyboInverter line was first released in 2013.
Products / operations. CyboEnergy develops, manufactures and markets solar power "Mini-Inverters" sold under the CyboInverter brand — multi-channel inverters with four DC input channels and per-panel MPPT, positioned between string inverters and microinverters. Product families span on-grid, off-grid, on/off-grid, dual-output off-grid and AC-assisted off-grid models (CIM-1000/1200 series), aimed at off-grid PV water heating, mini-split air conditioning, EV charging, microgrids and battery-less off-grid systems. It also offers CyboBridge monitoring gateways. Units are UL1741-certified and stated to be made in the USA.
Patent-litigation posture. In the tracked data CyboEnergy appears only as plaintiff (5 cases, 0 as defendant) — a purely offensive assertion posture, asserting its own inverter patents against competing solar-equipment vendors. Although the company self-describes as a manufacturer, Unified Patents characterizes it as an NPE and has run prior-art (PATROLL) contests against its patents. Filings cluster in plaintiff-friendly venues: W.D. Tex. (including Waco and Austin divisions) and E.D. Tex. (Marshall Division).
Notable cases. Tracked suits include CyboEnergy v. Yotta Energy (W.D. Tex. Austin, Aug. 2025, asserting U.S. Patents 9,331,488 and 9,331,489); v. Duracell Power Center (N.D. Cal., Dec. 2024); v. Hoymiles Power Electronics USA (E.D. Tex., 2023); v. Aptos Solar Technology (W.D. Tex. Waco, 2022); and v. Altenergy Power System USA. Third-party docket aggregators also list actions against Deye ESS Technology, Northern Electric Power and Sensata, plus several inter partes reviews defendants filed against CyboEnergy patents.

CyboEnergy, Inc. sued Deye ESS Technology USA and Ningbo Deye Inverter Technology Co., Ltd. asserting U.S. Patents 8,786,133 and 9,331,488. After an order to show cause regarding lack of prosecution, CyboEnergy filed a voluntary dismissal under FRCP 41(a)(1) on December 12, 2025, and the case was terminated.
CyboEnergy sued Yotta Energy asserting US 9,331,488 and US 9,331,489, with a jury demand. The case was pending with no further docket activity retrieved.
CyboEnergy sued Duracell Power Center asserting US 9,331,488 and US 9,331,489, including '489 claims 14, 15, and 16. The accused products include the Duracell Power Center D1500 Solar Power Micro-Inverter and D700 Solar Power Inverter; the case was pending.
CyboEnergy, Inc. sued Duracell Power Center, LLC in the Northern District of California; the narrative lists it among cases asserting the '133 patent, but the specific patents and pleading details were not confirmed in the retrieved material. The case was pending as of the last docket update.
CyboEnergy, Inc. sued Home Depot U.S.A., Inc. asserting U.S. Patents 8,786,133 and 9,331,488. CyboEnergy expressly withdrew its direct-infringement claim on the '133 patent and proceeded only on indirect infringement for that patent. The docket shows a stay and a notice of voluntary dismissal, and the case appears to have been voluntarily dismissed/stayed rather than litigated to judgment.
CyboEnergy sued Hoymiles Power Electronics USA asserting US 8,786,133 and US 9,331,489. On March 20, 2024, the court granted in part and denied in part Hoymiles' motion to dismiss, allowing the '489 indirect-infringement theories to survive; later status was not confirmed.
CyboEnergy sued Aptos Solar Technology asserting US 8,786,133 and US 9,331,489 over the Aptos MAC 800R microinverter. The parties filed a stipulation of dismissal on July 11, 2022, and the court sent the patent/trademark report to the USPTO.
CyboEnergy, Inc. sued Sensata, Inc. on October 15, 2021, asserting U.S. Patent 8,786,133. CyboEnergy later alleged that other defendants knew of the '133 patent from at least the Sensata filing date because Sensata used APsystems inverters. The outcome was not determined in the retrieved material.
CyboEnergy sued Altenergy Power System USA, asserting US 8,786,133 and US 9,331,489. The court dismissed the '133 allegations with prejudice on September 13, 2023, and later construed '489 claim 14 terms according to their plain and ordinary meanings; final disposition was not confirmed.
