SEOUL, South Korea A U.S. district court has ruled that Samsung Electronics Co. Ltd. and Matsushita Electric Industrial Co. Ltd. did not infringe on each other's DRAM-related patents, Samsung said Monday (Aug. 28).
The ruling by the district court in New Jersey on Friday (Aug. 25) stemmed from a lawsuit filed by Matsushita Electric in Jan. 2002. In the lawsuit, the Japan-based electronics giant sued Samsung for $300 million, accusing the world's largest memory chip maker of infringing three patents related to DRAMs for chips used in personal computers, according to Samsung.
"On Friday, the district court in New Jersey decided that Samsung did not infringe on Matsushita Electric Industrial's DRAM-related patents," a Samsung spokeswoman said.
She added the New Jersey court also rejected a lawsuit filed by Samsung in Nov. 2002, in which Matsushita was accused of infringing one of Samsung's DRAM-related patents.
She declined comment on whether Samsung accepted the court verdict. However, a Reuters report quoted a Matsushita spokesman as rejecting the ruling.
"Samsung violated Matsushita's chip patents, and this ruling is unacceptable," Reuters quoted the spokesman as saying. "We are studying necessary measures to overturn this verdict, including a possible appeal."
The two companies have traded several memory chip patent infringement suits. In Sept. 2005, Samsung filed a lawsuit against Matsushita in a U.S. court in Texas related to memory chip patents, triggering a countersuit by Matsushita in Texas in January.
