Agilent Wins Patent Dispute With Affymetrix For Microarray Hybridization

Agilent Technologies Inc. (Agilent) has won a patent dispute with Affymetrix Inc. (Affymetrix). The dispute was for "microarray hybridization," a way of labeling samples on a gene chip, a technology that allows scientists to analyze millions of genetic samples at once using a small plate.

A patent appeals board had ruled in favor of Affymetrix, as did the U.S. District Court for the Northern District of California. But the U.S. Court of Appeals for the Federal Circuit, which hears patent appeals, ruled that the lower court had made a series of mistakes, and reversed the California court’s decision.

In addition, the appeals court also said that both the companies would bear its own costs.

“The disputed invention focuses primarily upon the method of mixing the fluid for thorough contact with the microarray surface,” the ruling said.
