Case Highlight

Canon Inc. v. Color Imaging, Inc. et al. (N.D. Ga. 2017)

Michael served as lead trial counsel to Canon, enforcing a critical patent on Canon’s technology on toner bottles used in its imageRUNNER copy machines.  Following a 10 day trial, the jury returned a verdict for Canon on all issues, including direct infringement, induced infringement, contributory infringement and willful infringement, and on the affirmative defenses of exhaustion, implied license and repair, and awarded the full measure of damages sought.  The court subsequently awarded Canon a permanent injunction and enhanced damages.  In related PTAB proceedings, Michael and his team defeated institution on seven separate IPR petitions, with the Board’s decisions on the last five resulting in the expanded panel opinion in General Plastic v Canon, which the Board deemed to be of “exceptional importance” and gave the rare precedential designation.
