Rambus Stock On A Roll After Settlement With Hitachi
Shares of Rambus Inc. soared again Friday after the maker of interfaces for computer chips settled a patent-infringement lawsuit filed against Hitachi Ltd. by granting the Japanese electrical machinery maker certain patent licenses.
Stock of the Mountain View, Calif.-based company rose $17.56, or 18 percent, to close at $114.68 giving the shares a total gain of 551 percent since the beginning of the year.
The two companies signed a settlement agreement late Thursday giving Hitachi certain patent licenses for Rambus’ synchronous dynamic random access memory, or DRAM, devices and related products and terminating litigation against Hitachi.
In January, Rambus alleged that Hitachi infringed on Rambus’ patents for synchronous DRAM devices and Rambus filed lawsuits against Hitachi and Hitachi Semiconductor Inc. in the United States and Hitachi’s subsidiary in Germany.
Analysts had expected that Rambus, which makes interfaces to accelerate the speed of memory in computers and other gadgets, would see a favorable ruling in the lawsuit after Toshiba Corp., Japan’s second-largest manufacturer of microprocessors, agreed to pay royalties for the company’s memory technology on June 16.
