Affymetrix in new patents row

MIT files suit over GeneChip technology.

The Massachusetts Institute of Technology (MIT) has filed a lawsuit against DNA microarray company Affymetrix, claiming that some of the company's GeneChip technology — widely used for high-throughput genomic analysis — infringes an MIT patent.

Patent disputes are routine in biotechnology, but this one targets a business of growing importance for Affymetrix of Santa Clara, California.
