MRI technology developer NeuroGrafix filed two lawsuits in a New York federal court, charging Cornell University and Columbia University with patent infringement relating to its neuroradiology visualization methods.
NeuroGrafix is charging the universities with violating patents it holds for the methods as they are applied to MRI, CT, and diffusion tensor imaging (DTI). The firm says it was the first to publish a paper on diffusion anisotropy tractogram technology.
The actions are part of a wave of patent-infringement lawsuits the firm said it has filed over the past three months. Previous filings have targeted the U.S. National Institutes of Health, Brigham and Women's Hospital, Beth Israel Deaconess Medical Center, Tufts University, Boston University, Johns Hopkins University, and the University of Chicago, NeuroGrafix said.
Actions were also filed against Philips Healthcare and Brainlab, the company said. GE Healthcare has filed a declaratory judgment action against NeuroGrafix in Los Angeles and has intervened in the firm's dispute with the University of California, Los Angeles.
