Fujitsu Ltd has claimed to have won its patent litigation against Nanya Technology Corp. Japan, announcing that the Tokyo District Court has upheld its claims of DRAM patent infringement vs. the subsidiary of Taiwan's Nanya Technology Corp.

Fujitsu filed the patent litigation in August 2005, following a period of unsuccessful attempts to reach a licensing agreement with latter for a technology used to improve circuits that input data with address signals in DDR SDRAM, the patent for which Fujitsu claims.

"We are pleased that the court has confirmed our patent rights as well as granted our claims regarding infringement, injunction and damages," said Masanobu Katoh, corporate VP and president of the law and intellectual property unit of Fujitsu, in a statement released last week.

According to Fujitsu, the Tokyo District Court has found that DRAM products sold by Nanya Technology Corp. Japan infringe upon Fujitsu's patent rights. The court has granted an injunction against future import and sales of the infringing products, including compensation for past infringement. Immediately, Fujitsu filed an application with the Japan Customs seeking suspension of the import of infringing products by Nanya Technology Corp. Japan under the customs law.

Nanya responds
Responding to Fujitsu's claims, Nanya Technology bared in a statement released the day after Fujitsu's announcement that it was yet to receive the final ruling of the Tokyo District Court. The statement said the company intends to review its options regarding an appeal after it receives the judgment. The impact of the ruling will be minimal to both Nanya's operations and performance, added the company.

"The case with Fujitsu probably won't have much impact on Nanya in the near term because it's been going on for a while and the company has already made contingency plans," said Pai Pei-lin, VP of sales at Nanya Technology Corp. in an InfoWorld report. "Nanya will most likely appeal the decision, but company lawyers will have to take a close look at the ruling before making such a decision."

In addition to the Tokyo District Court litigation, Nanya is also involved in a litigation case against Fujitsu in the United States. According to the Taiwan DRAM maker, the U.S. Patent and Trademark Office (USPTO) has already granted Nanya's reexamination applications on three of the five Fujitsu's patents asserted against Nanya. Nanya expects the remaining two patents being asserted by Fujitsu, including the U.S. counterpart to the Fujitsu patent being asserted in Japan, will also be granted for reexamination by USPTO in the near future.

Nanya was previously involved in a DRAM patent litigation with Renesas Technology in 2003, which it has settled in May 2006 via a cross-licensing agreement.
