SAN FRANCISCOSanDisk Corp. has filed a complaint against LSI Corp. asking for a declaratory judgment of non-infringement of several patents held by that company.
The complaint, filed June 19 in U.S. District Court for the Northern District of California, also alleges unfair competition, intentional interference with prospective economic advantage and trade libel.
LSI (Milpitas, Calif.) declined to comment on the complaint through a spokesperson. SanDisk did not immediately respond to request for comment.
The complaint was first reported Monday by Filing Watch, a semiconductor-industry focused publication of Parallel Semiconductor LLC. Parallel Semiconductor is a provider of technology and IP services based in Phoenix.
According to the complaint, LSI initially contacted SanDisk in 2007 to initiate patent license negotiations for several of SanDisk's digital media players. LSI eventually alleged that SanDisk's media players violate a total of eight patents held by LSI, according to the complaint.
SanDisk (Milpitas) responded to the multiple inquiries by saying it did not believe its products violated the LSI patents, according to the complaint.
Last month, LSI sent letters to four SanDisk customers claiming that certain SanDisk products infringed the LSI patents, according to the complaint.
SanDisk is requesting that the court declare that its products do not infringe LSI's patents, according to the complaint.
SanDisk is also seeking unspecified damages for LSI's conduct, the complaint states. SanDisk claims it has "suffered harm in the form of damage to its reputation in the marketplace," and spent money on legal fees and costs to indemnify customers to pursue the legal action, the complaint states.
