Representative Experience

  • Represented Bayer Healthcare in a Hatch-Waxman trial against Watson in the United States District Court for the District of Delaware, relating to Watson’s effort to market a generic version of Bayer Healthcare’s erectile dysfunction drug vardenafil.  The Court ruled from the bench in Bayer Healthcare’s favor, upholding the validity of Bayer Healthcare’s patents directed to vardenafil.
  • Represented MedImmune in its declaratory judgment action challenging the “Queen patents” assigned to PDL BioPharma, among the most widely licensed patent portfolios in the biotechnology industry.  The court ruled on summary judgment that the asserted Queen patent was invalid as anticipated. 
  • Representing a biotechnology company in connection with district court litigation brought pursuant to the BPCIA concerning a biosimilar immunoadhesin drug.
  • Representing a biotechnology company in connection with inter partes review proceedings against patents related to client’s antibody drug.
  • Representing Bayer in a patent infringement suit brought by Biogen relating to Bayer’s genetically-engineered Interferon product for the treatment of multiple sclerosis.  The case involves the use of genetic engineering to identify the gene that codes for Interferon and to transform bacterial cells with plasmids containing the human DNA sequence to induce the bacteria to produce human Interferon.
  • Represented energy services company Petroleum GeoServices in inter partes review proceedings against Schlumberger subsidiary WesternGeco relating to patents directed to seismic surveying technology.  The PTAB canceled claims from three patents previously asserted by WesternGeco that were the subject of a district court judgment of validity and damages of over $100,000,000 against Petroleum GeoServices’ supplier.
