Representative Matters

• Represent Nichia, the world’s largest LED manufacturer, in a five-patent district court case and as lead counsel in inter partes review trials stemming therefrom. Achieved pre-institution stay of district court case. IPRs led to final written decisions finding unpatentable all claims asserted in district court.

• Represent LED manufacturers Nichia and OSRAM at the ITC and as lead counsel in multiple inter partes reviews over LED-package technology that threatened to exclude from the United States a substantial portion of the companies’ products. All asserted claims found not infringed, not supportive of a technical domestic industry, and/or invalid before the ITC. The IPRs further led to all asserted claims of one patent being found unpatentable and forced the patent owner to take claim-construction positions that led to non-infringement findings at the ITC.
