Defendant
2 cases as defendant.
Duracell Power Center, LLC is the trade-facing name for a US residential energy-storage business operated by Omega Green Power (d/b/a Power Center / PowerCenter+), headquartered at 5400 Hellyer Ave, San Jose, California. It is a private company and the North American licensee of the Duracell brand for energy storage systems — Duracell is a registered trademark of Duracell U.S. Operations, Inc., "used under license." Power Center's products are manufactured under license and warranted by Omega Green Power, a sister company of San Jose-based electronics manufacturer Omega EMS. The Duracell Power Center venture was formed around 2021–2022 as an Omega subsidiary; employee count and revenue are not publicly disclosed, and it is not publicly traded.
Products / operations. The company develops and sells an integrated home energy ecosystem: lithium-iron-phosphate battery storage (e.g., Dura 5, 51.2 V/5.12 kWh modules), hybrid inverters (MAX HYBRID 15 kW), solar microinverters (D700/D1500-series, D350-M1A/D600-M2A), and a residential EV charger (CHARGE 1), managed through a companion app and supporting virtual-power-plant participation. Assembly is performed in San Jose by Omega EMS. It is an operating company, not a shell licensor.
Patent-litigation posture. In the tracked data Duracell Power Center appears once, solely as a defendant (0 plaintiff cases, 1 defendant case) — the classic posture of an operating company being sued rather than an asserter. The single suit is in the Northern District of California, not the plaintiff-friendly Eastern/Western District of Texas venues CyboEnergy has used in other actions.
Notable case. CyboEnergy, Inc. v. Duracell Power Center, LLC (N.D. Cal., 3:24-cv-08891, filed 2024-12-10) asserts U.S. Patent Nos. 9,331,488 ("Enclosure and message system of smart and scalable power inverters") and 9,331,489 ("Maximizing power production at low sunlight by solar power mini-inverters") against Duracell Power Center's D1500 and D700 solar inverters. CyboEnergy is characterized by Unified Patents as an NPE that has asserted these microinverter patents against multiple manufacturers (Sensata, Northern Electric Power, Altenergy, Hoymiles, Home Depot, Yotta, Deye). Separately, Eguana Technologies disclosed a March 2025 settlement with Duracell Power Center terminating a 2024 collaboration agreement.
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.
