Memory chip maker Rambus wins patent trial

US company Rambus scored a key victory in its nearly decade-old fight with memory chip makers when a jury found the company did not engage in monopolistic behavior by patenting technologies that eventually became standard in memory chips, an Associated Press report said.

The Associated Press report said the jury's decision could help Rambus as it tries to collect millions of dollars in royalties on patents some of the biggest memory chip makers claim were fraudulently obtained.

Rambus makes most of its money by licensing patented chip designs that were created by its engineers and used widely by other companies in their DRAM chips, or dynamic random access memory, the most common type of memory chip used in personal computers, the report said.

However, Rambus still faces major court battles over its patents, including its attempt to overturn a 2006 Federal Trade Commission ruling that the company deceived a standards-setting committee and created a monopoly in the memory chip industry, the report added.
