Roche Diagnostics Says Judge Ruled in Its Favor in Enzo Diagnostic Case

This article has been updated to include the total number of patents under dispute. Enzo claims that several firms infringe eight of its patents.


NEW YORK, July 21 (GenomeWeb News) - Roche Diagnostics today said that a New York district judge ruled in its favor on key aspects of Enzo Biochem's patent-infringement case against the company.


According to Roche, the judge adopted "virtually all" of the interpretations proposed by Roche and its co-parties relating to seven Enzo patents.


Enzo earlier this week claimed the judge supported its patent-infringement claims against Affymetrix, Roche, Amersham, PerkinElmer, Sigma Aldrich, Orchid Biosciences, and Molecular Probes for eight of its patents.


The litigation, first filed in 2002, concerns products and techniques for detecting genetic information in biological samples, such as blood. Enzo claimed Roche's AmpliChip CYP450 Test infringed its patent covering the "soluble signal" and the testing format.
