Infineon Technologies AG, whose daughter maker of memory Qimonda ceased to exist last year, on Tuesday announced that the company and its subsidiary Infineon Technologies North America Corp. have filed a complaint with the U.S. International Trade Commission (ITC) against Elpida Memory.


The complaint asserts that Elpida has engaged in unfair trade practices by making for importation into the United States, and selling after importation, certain dynamic random access memory (DRAM) semiconductors and products that infringe four of Infineon's patents covering key inventions in semiconductor processing and device manufacturing.

“Infineon has always been at the forefront of advanced semiconductor processing technologies. We will protect our intellectual property rights, which arise from our commitment to cutting-edge research and development,” said Hermann Eul, member of the management board, sales, marketing, technology and research and development at Infineon Technologies.

Infineon's complaint with the ITC seeks an exclusion order that operates to bar from entry into the U.S. infringing DRAM semiconductors and products that are imported by or on behalf of Elpida.

Back in 2009 Elpida Memory of Japan acquired certain DRAM assets from the bankrupt Qimonda. In particular, Elpida obtained intellectual property it needed to build and sell GDDR5 memory chips.
