Representative Experience – Litigation*

  •  Lead counsel in patent litigation for a drug-device combination for delivery of the third best-selling prescription drug in the United States.  The litigation involved assertion of both drug and device patents against another innovator seeking to market a competitive product through the 505(b)(2) FDA approval pathway.  On the morning of trial, just before opening statements, the defendant consented to, and the District of Delaware entered, an order enjoining the defendant from selling its proposed product for more than a year.  As part of the negotiated resolution of this dispute, the Defendant further agreed to a royalty-bearing license to certain of our client’s patents. (October 2015)
  • Lead counsel in week long evidentiary hearing in a False Claims Act case alleging over $7billion in damages.  At issue were pharmaceutical development experiments that the Relator claimed revealed a pharmaceutical company had misled a federal agency to obtain an illegal monopoly over a drug product thereby fraudulently inducing the government to reimburse inflated prices for the drug when the cost of its use was reimbursed under Medicare and Medicaid.  (July 2015).  The Judge ruled favorably for Ms. Davies’s client, dismissing all claims with prejudice, and the case is now on appeal.
