SanDisk Corp. reported today that the U.S. Court of Appeals for the Federal Circuit (CAFC) reversed a summary judgment ruling of non-infringement by a California District Court regarding SanDisk's U.S. Patent No. 5,602,987 ("'987 Patent") on July 8.
As a result of the decision, SanDisk said it would renew the prosecution of its infringement claims against Ritek, Pretec and Memorex flash memory cards.
SanDisk said the CAFC ruling supports its interpretation of the key inventive features claimed in the '987 patent, and thereby eliminates the primary non-infringement argument of Ritek, Pretec and Memorex.
SanDisk expects to seek summary judgment of infringement against the accused Ritek, Pretec and Memorex flash memory cards.
The '987 Patent, issued in February 1997, teaches and claims important aspects of the emulation of a magnetic disk drive in removable flash memory storage products, such as SD Cards, Memory Stick Pro, USB flash drives, certain portable flash audio players, CompactFlash, and MultiMediaCards among others.
The inventions of the '987 patent enable flash memory cards and other storage products to achieve enhanced performance, reliability and host platform compatibility, the company said.
“We are very pleased with the decision handed down by the CAFC and believe this reaffirms the important and fundamental nature of SanDisk’s patented technology,” said E. Earle Thompson, chief intellectual property counsel for SanDisk, in a statement.
“SanDisk will continue to protect its investment in intellectual property and vigorously enforce its patents against companies that seek to use SanDisk’s patented technology without a license,” he concluded.
