Illumina Countersues Life Technologies

San Diego-based Illumina (NASDAQ: ILMN) and its Solexa subsidiary are countersuing Carlbad, CA-based Life Technologies (NASDAQ: LIFE) and Applied Biosystems in a patent dispute over gene sequencing technologies. In a statement today, Illumina and Solexa denied allegations that Life and Applied Biosystems raise in their Sept. 21 lawsuit, assert that Applied Biosystems’ patents are invalid, and allege that Life is infringing on four Solexa patents. A Life spokesman says, “We believe these claims are without merit and we will vigorously defend our intellectual property.”
