Chip designer Rambus has won more than $300m (£167m) in damages from Hynix Semiconductor after a month-long patent infringement court case.
A jury in the US District Court in San Jose, California found that all 10 of Rambus’s patent claims were valid and had been infringed by Hynix. The jury awarded Rambus $306.9m in damages.
Rambus has also asked for an injunction against Hynix to stop the manufacture, use, sale or import of any other Hynix memory products that infringe its patents. The case is set to be heard after a series of Hynix counterclaims, expected to come before the courts in the summer.
The Hynix case could affect a series of other lawsuits filed by Rambus against chip manufacturers, claiming that their memory chips breach its patents. It has cases outstanding against Micron, Samsung and Nanya.
In March last year, the company settled a five-year dispute with Infineon over an alleged breach of its DRAM memory patents. But just two months later Rambus was again embroiled in patent litigation, suing Samsung, which in turn launched its own lawsuit against Rambus.
