Aug 10 (Reuters) - Chipmaker Navitas NVTS.O sued Japan-based rival Renesas 6723.T in Texas federal court on Monday for allegedly violating its patent rights in next-generation computer chip innovations.
Torrance, California-based Navitas alleged that Renesas' gallium nitride-based (GaN) semiconductors, which are increasingly used to power AI data centers, infringe four of its GaN patents.
Navitas' complaint follows a Renesas lawsuit filed last month that accused Navitas and its CEO Christopher Allexandre of stealing Renesas' GaN trade secrets.
Renesas' July complaint ⁠said the global market for GaN chips is expected to grow from $355 million in 2024 to $3 billion by ​2030, largely due to the rapid growth of ​AI-powered technology.
A Renesas spokesperson declined to comment on Navitas' lawsuit.
"We respect valid intellectual property rights and we expect our competitors to do likewise," Allexandre said in a statement.
Navitas asked the Texas court for an unspecified amount of monetary damages and a court order blocking Renesas from infringing its patents.
The case is Navitas Semiconductor Ireland LLC v. Renesas Electronics Corp, U.S. District Court for the Eastern District of Texas, No. 2:26-cv-00676.
For Navitas: Michelle Armond, Douglas Wilson and Monica Arnold of Armond Wilson
For Renesas: attorney information not yet available
