Navitas Semiconductor has filed a patent infringement lawsuit against Renesas Electronics in the U.S. District Court for the Eastern District of Texas, escalating intellectual-property competition within the rapidly growing GaN power semiconductor market.
The lawsuit alleges that major Renesas GaN product lines, including its SuperGaN power semiconductors, infringe four Navitas U.S. patents: Nos. 9,929,079; 11,545,838; 11,770,010; and 11,862,996. Navitas said the patents form part of its broader GaN intellectual-property portfolio developed through its internal research and engineering activities.
Navitas has built a global IP portfolio of more than 300 issued and pending patents spanning its wide-bandgap semiconductor technologies. The company argues that protecting this intellectual property is increasingly important as GaN adoption expands beyond consumer power adapters into higher-power applications.
The legal action comes as Navitas shifts its growth strategy toward AI infrastructure, including AI data-center power systems and the energy and grid infrastructure supporting them. The company said momentum in these higher-power markets contributed to its second-quarter 2026 performance and that it expects revenue growth to accelerate in the third quarter as it executes its Navitas 2.0 strategy.

Wolfspeed and LITEON Technology have formed a strategic partnership following the successful qualification of Wolfspeed’s silicon carbide technology for LITEON’s 800VDC power sidecar and compute-rack power supply unit platforms. The systems are being developed for next-generation AI data centers serving leading hyperscale customers, with potential adoption across additional cloud service provider platforms.
The collaboration represents another significant commercial entry point for SiC beyond its established automotive and industrial markets. Rapidly increasing AI compute power requirements are pushing data center operators toward 800VDC architectures, where higher distribution voltages can improve efficiency, increase power density and support the scaling of increasingly power-intensive AI racks.
LITEON will use Wolfspeed SiC MOSFETs within these architectures to improve power-conversion efficiency across a broad operating range. According to the companies, the technology can also reduce bill-of-material costs and simplify component procurement, making SiC attractive not only from an efficiency perspective but also at the overall system level.
A strategically important element of the partnership is Wolfspeed’s 200mm SiC manufacturing platform. LITEON plans to leverage this manufacturing capability as it develops power systems intended for hyperscale deployments, where semiconductor availability, manufacturing scale and supply-chain reliability become increasingly important as deployments move from qualification into volume production.
The qualification provides Wolfspeed with direct exposure to the emerging 800VDC AI data center power ecosystem. While no revenue, volume or deployment timetable was disclosed, successful qualification for LITEON’s power sidecar and compute-rack PSU platforms creates the potential for Wolfspeed devices to scale alongside future hyperscale and CSP deployments.
For LITEON, the partnership strengthens its ability to offer high-efficiency and high-reliability power infrastructure as AI data centers transition toward higher-voltage DC distribution. Wolfspeed CEO Robert Feurle highlighted the combination of advanced SiC technology and scalable supply capacity, while LITEON said the integration strengthens the performance, efficiency and reliability of its next-generation AI infrastructure platforms.
From a power semiconductor market perspective, the announcement is another indication that AI infrastructure is developing into an important incremental demand driver for SiC. Historically dominated by EV traction inverters, renewable energy and industrial applications, SiC is increasingly being positioned in high-power AI data center PSUs, BBUs and 800VDC distribution architectures. If hyperscale adoption accelerates, this could broaden the SiC demand base and create a meaningful new growth market for high-voltage SiC MOSFET suppliers such as Wolfspeed.

Power Integrations has announced a major extension of its PowiGaN gallium nitride technology to a 2200 V rating, which the company says exceeds the voltage capability of other commercially available GaN technologies. The development significantly expands the addressable voltage range for GaN and targets emerging high-voltage applications including AI data centers, electric vehicles, renewable energy, battery storage and HVDC infrastructure.
The 2200 V technology is particularly relevant as power architectures migrate toward higher DC bus voltages to improve efficiency and power density. Power Integrations highlighted next-generation AI data centers as a major opportunity, with industry roadmaps moving beyond today’s 800 VDC architectures toward potential 1500 V distribution systems. The additional voltage headroom provided by 2200 V GaN could enable designers to use GaN in applications where voltage requirements have historically favored silicon carbide.
Power Integrations is already extending GaN into these higher-voltage systems. Its 1700 V PowiGaN ICs are being designed into single-stage auxiliary power applications in data centers, while 1250 V devices provide an alternative to stacked lower-voltage switches in the main power path of 800 VDC architectures. The new 2200 V platform pushes this strategy further by providing sufficient voltage margin for future higher-voltage buses.
The development is strategically important for the competitive positioning of GaN versus SiC. GaN has traditionally delivered advantages in switching frequency and power density but has been constrained by lower commercially available voltage ratings. High-voltage applications have therefore remained an important stronghold for SiC. By extending GaN to 2200 V, Power Integrations is attempting to bring GaN’s high-frequency characteristics into applications previously considered beyond its practical voltage range.
The potential system-level impact could be significant. Higher-voltage GaN devices could reduce the need to series-connect multiple lower-voltage switches, simplifying power stages while reducing component count and potentially improving power density and reliability. Power Integrations specifically identifies solar inverters, HVDC systems, advanced industrial power conversion, EV systems and data center infrastructure as potential applications.
The announcement also highlights how AI infrastructure is accelerating technology competition between GaN and SiC. Yole Group analyst Roy Dagher noted that GaN’s historical voltage ceiling has limited its participation in the main power path of high-voltage data center architectures, leaving much of this opportunity to SiC. According to the figures cited in the announcement, Yole expects the power GaN device market to reach $3.5 billion by 2031.
