USPTO gives ruling on EPC patent disputed by Innoscience
The USPTO strengthened EPC's core GaN patent but cancelled two claims central to a prior ITC ruling against Innoscience for infringement. EPC will appeal the cancellation, continuing the legal uncertainty. Watch: This ongoing patent dispute introduces supply chain risk for Innoscience's GaN components, potentially affecting market availability and pricing if enforcement actions resume.

MACOM signs preliminary memorandum of terms for US CHIPS Act funding
MACOM has signed a preliminary agreement for CHIPS Act funding, positioning it to receive US government support for its RF, microwave, and optical semiconductor production. This funding aims to bolster domestic manufacturing of critical technologies for commercial and defense applications. Watch: This signals potential long-term capacity and R&D investment in specialized analog/RF components, but the direct, near-term trading impact on supply and pricing is uncertain.

Wolfspeed announces $750m in proposed funding from US CHIPS Act plus $750m from investment group
Wolfspeed has secured a non-binding PMT for up to $750M in direct CHIPS Act funding and an additional $750M in private financing. This capital is intended to support the expansion of its silicon carbide materials and device manufacturing capacity in the US. Watch: The funding strengthens Wolfspeed's long-term supply position but does not indicate an immediate change in SiC market supply or pricing.

Innoscience claims victory over EPC’s ’508 patent in ITC’s initial decision
Innoscience claims a favorable initial determination at the US ITC, defeating the entirety of EPC's '508 patent. This legal victory removes a potential import ban threat for Innoscience's GaN power devices in the US market. Watch: This reduces supply chain disruption risk for Innoscience's customers but may intensify competition in the GaN power component segment.

Wolfspeed’s supply chain not impacted by China’s export restrictions on gallium and germanium
Wolfspeed states its supply chain will not be impacted by China's export restrictions on gallium and germanium, effective August 1st. The company conducted an internal review of its supply chain for these materials used in SiC and GaN production. Neutral: This removes a potential supply risk for a major SiC/GaN producer, but does not indicate a broader market impact.

North American GaN device makers confirm continuity of gallium sourcing despite China’s export restrictions
North American GaN device manufacturers have issued statements affirming continuity of gallium supply following China's export restrictions on gallium and germanium. This addresses a key supply chain risk for a critical raw material used in GaN power semiconductors. Watch: The market impact depends on the effectiveness of alternative sourcing and potential long-term price pressure on gallium.

EPC sues Innoscience at ITC for GaN power device patent infringement
EPC has filed patent infringement lawsuits against Innoscience in US federal court and at the International Trade Commission (ITC), asserting four foundational GaN patents. The ITC complaint specifically seeks an exclusion order to ban Innoscience's accused GaN power devices from importation into the United States. Watch: This legal action introduces significant supply chain uncertainty for Innoscience's GaN products in the US market, potentially disrupting availability and shifting demand to other suppliers if an exclusion order is granted.
