It was the third trial between VLSI and Intel over different patents related to chip-making technology. VLSI won a $2.18 billion verdict in Waco, Texas, in March 2021. Intel was cleared of infringement in a trial the following month.
In closing arguments on Tuesday, VLSI’s attorney Morgan Chu of Irell & Manella LLP said that Intel infringed US Patent No. 7,606,983, which covers an invention that helps keep information flowing through computer processors.
VLSI’s patent “improved performance” by putting computer processor traffic “on the equivalent of the fast lane,” Chu said. “There are millions and millions of infringements per second in the Intel chips.”
A lawyer for Intel, Bill Lee of Wilmer Cutler Pickering Hale and Dorr LLP, countered that the technology described in the patent isn’t used in modern microprocessors.
He also said “there’s not a shred of evidence” Intel’s engineers copied the ‘983 patent. Lee said “they want you to think Intel’s engineers just stumbled into infringing the patent,” but their testimony “documents that their products operate differently.”
Additionally, Lee argued that the ‘983 patent isn’t valid because the same technology was covered by an earlier patent that was not considered by the patent examiner.
After 4 1/2 hours of deliberations, the jury of three women and four men announced their verdict.
The latest verdict comes amid active patent litigation between Intel and VLSI in federal courts in California and Delaware, as well as in Shanghai and Shenzhen in China. The US Court of Appeals for the Federal Circuit on Tuesday revived portions of another VLSI patent that had been wiped out by the Patent Trial and Appeal Board.
Administrative reviews of patents underlying a prior Intel-VLSI verdict remain ongoing, with one recently triggering sanctions and a second look from the US Patent and Trademark Office’s director following her initial remand.
