Patents expert witnesses may opine on patent infringement, software patents, invention patents, and more. In the news this week, Carnegie Mellon University has been awarded almost $1.17B in its patent infringement lawsuit against Marvell Technology Group Ltd. The jury found that Marvell, maker of data storage chips, infringed on Carnegie Mellon technology patents while Marvell argued that the patents were not valid. The Pittsburg jury found that Marvell had sold billions of chips incorporating technology developed by Carnegie Mellon Professor Jose Moura and doctoral student Aleksandar Kavcic. Judge Nora Barry Fischer presided in the W.D. Pa. case (2:09-cv-00290-NBF).
