NEW YORK, Feb. 19 - Amersham Pharmacia Biotech last week definitively lost the patent infringement suit it filed against Millipore and its British subsidiary more than two years ago, Millipore said.
The decision came from the British House of Lords, which said that Amersham could not appeal a court ruling last summer that found in Millipore's favor.
This ruling, announced in a statement released on Feb. 15, effectively resolves the suit.
In September 1999, Amersham filed suit against Millipore claiming that the Millipore IsoPak biochromatography columns infringed upon Amersham patents on its own Chromaflow chromatography columns. Amersham sought an injunction as well as damages.
In July 2001, the British Court of Appeals, affirming the decision of the High Court, said that Millipore's chromatography valve did not infringe upon Amersham's British patents.
