Illumina Countersues Life Technologies

San Diego-based life sciences firm Illumina reports today that it has countersued Life Technologies, after Life and Applied Biosystems sued the firm in September over patent infringement. Illumina said that it has denied the allegations of patent infringement, and sued Life and Applied Biosystems over its own patents. Illumina said that its patents--U.S. Patent Nos. 6,831,994; 6,654,505; 7,232,656; and 7,598,035--cover various aspects of Life's SOLiD sequencing system. Illumina is seeking a permanent injunction of sales of Life's SOLiD system, destruction of infringing SOLiD system products, and damages.
