What do you do when a key witness falls ill and is no longer able to testify? Judge Robinson in Genetics Institute, LLC v. Novartis Vaccines and Diagnostics, Inc. excused the inventor/witness from testifying based on a letter from her doctor. She noted, however, that “because it is not clear from the submission how the diagnosed condition is affecting [the inventor’s] daily life, sanctions will be imposed against [the defendant] in this case if [the inventor] provides any testimony (through a declaration, a deposition or at trial) in any other case involving the patents at bar.” C.A. No. 08-290-SLR, Order (D. Del. Oct. 23, 2009). She further stated that “[d]epending on the circumstances, I would consider sanctions ranging in severity from the imposition of an adverse inference to the imposition of the costs of a new trial to the imposition of an adverse judgment.” Id.
