Efficient Power Conversion (EPC) announced that it has moved one step closer to achieving preeminence in the gallium nitride (GaN) power semiconductor industry, as its intellectual property rights to this revolutionary technology were upheld for the third time in three months. The next-generation wide bandgap semiconductors developed by EPC are essential to artificial intelligence (AI), satellites, fast chargers, lidar, humanoid robots and many other transformational technologies.
The U.S. International Trade Commission (ITC) found two of EPC’s key patents valid and one, the Company’s foundational patent, infringed by Innoscience (Zhuhai) Technology Co., Ltd. and its affiliate, Innoscience America, Inc. The ITC’s recommendation comes on the heels of two recent decisions from the China National Intellectual Property Administration (CNIPA), which similarly validated EPC’s counterpart patents in China. The ITC initial determination is a significant milestone in solidifying EPC’s leadership in wide bandgap semiconductors and could lead to a ban later this year on importation of Innoscience’s infringing products into the United States.
“The ITC’s finding that Innoscience uses our patented technology without authorization puts EPC in an enviable position, as U.S. and Chinese regulatory bodies have upheld the validity of our patents,” said Alex Lidow, CEO and Co-Founder of EPC.
“The Commission’s recommendations validate nearly two decades of hard work, resources and R&D that went into developing EPC’s uniquely valuable intellectual property portfolio,” Dr. Lidow added.
Over the last 15 years, EPC has capitalized on its first-mover advantage to develop a broad portfolio of over 200 GaN-related patents and over 150 products, which include its rapidly growing family of integrated circuits, automotive qualified and radiation hardened devices.
Compared with traditional silicon-based power devices, GaN represents a significant leap, with higher efficiency, faster switching speeds, smaller size and lower cost. GaN power devices are integral to self-driving vehicles, medical and communications devices, next-generation rapid chargers, drones, satellites, data centers, e-bikes, solar power systems and humanoid robots, among many other applications. Most notably, EPC’s cutting-edge semiconductors are central to powering the AI revolution by significantly freeing up space for extra computing power while simultaneously reducing energy consumption.
The ITC’s preliminary ruling found both U.S. patents that EPC asserted against Innoscience valid. It also found “infringement [by Innoscience] of U.S. Patent No. 8,350,294,” EPC’s foundational patent used broadly across multiple industries. The second EPC patent, U.S. Patent No. 8,404,508, was found valid, but not infringed by Innoscience. The Commission’s final determination is expected to be issued on November 5, 2024.

Vishay Intertechnology, Inc. introduced 16 new Gen 3 1200 V silicon carbide (SiC) Schottky diodes. Featuring a merged PIN Schottky (MPS) design, the Vishay Semiconductors devices combine high surge current robustness with low forward voltage drop, capacitive charge, and reverse leakage current to increase efficiency and reliability in switching power designs.
The next-generation SiC diodes released today consist of 5 A to 40 A devices in the TO-220AC 2L, TO-247AD 2L, and TO-247AD 3L through-hole and D2PAK 2L (TO-263AB 2L) surface-mount packages. The diodes offer a low capacitance charge down to 28 nC, while their MPS structure — which features a backside thinned via laser annealing technology — delivers a reduced forward voltage drop of 1.35 V. In addition, the devices’ low typical reverse leakage current down to 2.5 µA at 25 °C reduces conduction losses, ensuring high system efficiency during light loads and idling. Unlike ultrafast diodes, the Gen 3 devices have virtually no recovery tail, which further improves efficiency.
Typical applications for the diodes will include AC/DC PFC and DC/DC ultra high frequency output rectification in FBPS and LLC converters for solar power inverters; energy storage systems; industrial drives and tools; and datacenters. For the harsh environments of these applications, the devices combine operating temperatures to +175 °C with forward surge ratings to 260 A for high robustness. In addition, diodes in the D2PAK 2L package feature a molding compound with a high CTI ≥ 600, ensuring excellent electrical insultation at elevated voltages.
Offering high reliability, the RoHS-compliant and halogen-free devices have passed higher temperature reverse bias (HTRB) testing of 2000 hours and temperature cycling testing of 2000 thermal cycles.
