NEW YORK, Oct. 23-Enzo Biochem has filed suit against Amersham, PerkinElmer, Orchid Biosciences and two other companies for breach of contract and patent infringement, the company said today.
The suit, filed in the U.S. District Court for the Southern District of New York, alleges that these companies have misused Enzo's nucleotide labeling technologies, methods used in gene sequencing and analysis.
Amersham Biosciences, PerkinElmer and Sigma-Aldrich, three of the defendants in the suit, had all signed agreements to distribute Enzo's labeled nucleotide products. Enzo claims that these three distributors were permitted only to distribute these products for research use, but violated their agreements by developing the technology for clinical use, exploiting Enzo's patents without authorization.
The other defendants, Orchid and Molecular Probes, are charged with patent infringement.
Enzo's corporate headquarters are in New York, NY.
