  • Fujifilm Corp. v. Papst Licensing GmbH & Co. KG.: On behalf of Fujifilm, we won all eight IPRs filed against Papst Licensing. As part of ongoing litigation with Papst, our client joined forced with digital camera and mobile phone manufacturers to attack the validity of two patents concerning USB functionality. We took the lead on two of the eight IPRs, and were heavily involved in the other six. The PTAB ruled all instituted claims unpatentable. Moreover, since all the claims asserted against Fujifilm were ruled unpatentable on four separate, independent grounds, we have made significant headway towards defeating Papst in the remaining litigation.
