May 5, 2009: Microarray developer Illumina Inc. said it has filed a patent infringement lawsuit against another microarray developer, Affymetrix Inc., according to a report in the San Jose Business Journal.
Illumina said the lawsuit, filed in a Wisconsin district court, alleges that the Affymetrix GeneChip HT Array Plate and GeneChip HT Array Plate Scanner infringe upon an Illumina patent.
The patent, issued on March 31, is titled, “Methods of Making and Using Composite Arrays for the Detection of a Plurality of Target Analytes.” Illumina is asking the federal court to enjoin Affymetrix from continuing to make and sell its HT Array Plate and Scanner products, as well as for unspecified monetary damages.
