Mr. Green has represented clients under the Hatch- Waxman Act since it was passed in 1984.

Since founding Green Griffith, Mr. Green successfully defended Dexcel against alleged infringement of Takeda’s Orange Book-listed patents for lansoprazole delayed-released orally disintegrating tablets (“ODT”).

In addition, Mr. Green has been instrumental in obtaining favorable settlements for Horizon Pharma in litigations related to Abbreviated New Drug Applications filed by various generic drug companies. Mr. Green also was counsel for Cipla in litigation relating to Cipla's ANDA that sought approval to market a generic equivalent to Helsinn's Aloxi® palonosetron product. That litigation settled with a favorable generic product entry date.
