AstraZeneca Pharmaceuticals Inc. filed a motion on Wednesday to block Dr. Christopher Reist from testifying for Handa Pharmaceuticals LLC, a rival pharmaceutical company, in an ongoing patent infringement case over AstraZeneca’s Seroquel XR®. Dr. Reist worked on the clinical trials for Seroquel XR® between 2001 and 2007 as one of it’s paid speakers. Handa has selected Dr. Reist as an expert witness in the infringement case, something AstraZeneca states will create a conflict of interest. AstraZeneca is represented by Finnegan.
