Patent infringement

Mosaid Technologies has filed a law suit against Infineon Technologies for patent infringement.


Mosaid Technologies has filed a law suit against Infineon Technologies and three of its US-based affiliates for infringement of three of Mosaid’s United States patents – 6,657,919 and 6,057,676 and US Reissued Patent RE 37,641.


The suit was filed in the US District Court for the Eastern District of Texas, Tyler Division.


In its complaint, Mosaid claims that Infineon has infringed, and is infringing its patents by making and selling products, including DRAMs.


“These are patents from three patent families which Mosaid refers to as its delay locked loop, cell plate voltage and bit-line isolation families,” said Jim Skippen, Senior Vice President, Patent Licensing and General Counsel of Mosaid.


This is the second time Mosaid has brought a law suite against Infineon. In its first attempt in a New Jersey Court, it claimed that Infineon had infringed Mosaid patents 5,822,253, 5,751,643, 6,278,640, 5,828,620, 6,055,201 and 6,580,654 and 6,603,703.


But on April 4, the District Court for the District of New Jersey ruled that ruled that Infineon’s products did not infringe the 5,822,253, 5,751,643, 6,278,640, 5,828,620, 6,055,201 and 6,580,654 patents, but did not make any ruling as to whether or not the 6,603,703 patent was infringed.


“The three patent families in this Texas litigation are different than the two patent families at issue in the New Jersey litigation with Infineon,” said George Cwynar, President and Chief Executive Officer of Mosaid.


“We believe this second litigation is further evidence of the breadth of Mosaid’s patent portfolio. The fact that Mosaid is able to bring litigation on multiple patent families also demonstrates why twelve major companies have taken comprehensive licenses to Mosaid’s patent portfolio.”
