He has successfully litigated cases in every major patent venue across the US, including district courts, the International Trade Commission (ITC), and the Patent Trial and Appeal Board (PTAB), both as plaintiff and defense counsel.Dale has played significant roles in over 20 trials. In 2024, Dale, Marc Fenster, and Reza Mirzaie led the RAK team that won a $262 million jury verdict, and a resulting judgment of $380 million, against Western Digital on patents related to magnetic recording media in hard disk drives. Dale presented plaintiff MR Technologies’ infringement and validity expert, and the jury found all five asserted claims infringed and valid. In 2022, Dale notched three trial wins in a row, starting with a complete defense victory for Irving Consumer Products against First Quality in an April 2022 Delaware jury trial on tissue products. That was followed by a plaintiff-side win for Philip Morris in a June 2022 Virginia jury trial against RJ Reynolds on vaping devices. Dale capped the year off with a complete defense victory for SMR against Magna in a December 2022 Michigan jury trial on side-view car mirrors.In addition to his recent jury wins, Dale first-chaired a PTAB trial in a pivotal IPR of a patent on which the patentee had prevailed at the ITC. The PTAB found all claims invalid in January 2022. Earlier that month, Dale obtained another complete victory from the PTAB, in a post grant review of a patent asserted in district court. He has since first-chaired several other PTAB trials with a 100% win rate.Dale has also successfully litigated trade secrets cases, including LG Chem’s landmark 2020 win at the ITC in its high profile trade secrets case against SK Innovation on electric car batteries.Other notable achievements include 2018, 2016, and 2014 jury wins in the Eastern District of Virginia and the District of Delaware as well as major victories at the ITC in 2020, 2017, and 2015.Prior to joining Russ August & Kabat, Dale was counsel at Latham & Watkins, where he litigated IP cases for over 15 years.
