  • Won a $14.5 million verdict on behalf of a DSM Bio-Based Products & Services in a jury trial involving patented yeast used for industrial-scale production of ethanol from corn stock. (DSM v. Lallemand, W.D. Wisconsin, 2018)

  • Won three IPRs on behalf of Endo Pharmaceuticals involving patents covering its Opana® ER product. One IPR was dismissed at the institution phase because it was untimely. The other two IPRs went to Final Written Decision, with the PTAB agreeing that the generic challenger had failed to show that the claimed pharmaceutical dissolution rates were disclosed in or suggested by the prior art, a holding that was summarily affirmed on appeal. (Amneal Pharms. v. Endo Pharms., 2015)
  • Won a series of IPRs on behalf of patent owner DSM involving patents covering glass optical fiber coating technology, with more than 70% of the 225 challenged patent claims being upheld. These IPRs were some of the first in which the PTAB granted a patent owner's motion for additional discovery. (Corning v. DSM, 2014)
