"For BD, this pioneering technology has opened the door to new business opportunities and provided a competitive advantage, allowing it to build market leadership and strengthen its brand as the innovator in flow cytometry reagents, both in the research-use-only market as well as the clinical diagnostics market," the lawsuit further stated. "These dyes allow scientists efficiently to label and detect biological materials of interest in a sample, including small populations of difficult to detect proteins and cells," the lawsuit noted. The BD polymer dye chemistries allegedly infringed were originally developed by BD subsidiary Sirigen.
The lawsuit accuses Beckman of "developing and launching copycat polymer dye products," and seeks a permanent injunction against further infringement as well as "treble damages" due to alleged willful and deliberate infringement. The SuperNova dyes are used in Beckman's flow cytometry technology, CytoFlex, which launched commercially in March.
In documents filed last week with the US District Court for the Southern District of California, BD alleged that Beckman Coulter's SuperNova fluorescent polymer dye technology infringes on BD patents pertaining to dye chemistries. NEW YORK – Becton Dickinson has sued Danaher subsidiary Beckman Coulter alleging infringement of 13 patents related to flow cytometry. Advances in Clinical Genomics Profiling.
