INFORMATION TO BE INCLUDED IN THE REPORT

 

Item 1.01. Entry into a Material Definitive Agreement

On September 10, 2007 (the “Effective Date”), Repligen Corporation (“Repligen”) and the Massachusetts Institute of Technology (“MIT”) entered into a settlement agreement (the “Settlement Agreement”) with ImClone Systems, Incorporated (“ImClone”) relating to the lawsuit against ImClone for infringement of U.S. Patent No. 4,663,281 based on ImClone’s manufacture and sale of Erbitux®. The Settlement Agreement provides for ImClone to make a payment of $65 million to co-plaintiffs Repligen and MIT and will result in net proceeds to Repligen of approximately $40 million after payment of obligations to MIT and legal expenses. The Settlement Agreement serves as the basis for Repligen and MIT to dismiss the lawsuit against ImClone and Repligen has granted ImClone a non-exclusive sublicense to certain patent rights.

In May 2004, Repligen and MIT filed an action in the United States District Court for the District of Massachusetts against ImClone for infringement of U.S. Patent No. 4,663,281 based on ImClone’s manufacture and sale of Erbitux®. The patent, which covers the use of certain genetic elements that increase protein production in a mammalian cell, is assigned to MIT and exclusively licensed to Repligen.

 

Item 7.01. Regulation FD Disclosure

On September 10, 2007, Repligen announced in a press release that on September 10, 2007, Repligen, MIT and ImClone executed a Settlement Agreement, which serves as the basis for Repligen and MIT to dismiss all patent litigation against ImClone and Repligen has granted ImClone a non-exclusive license to certain patent rights. The full text of the press release issued in connection with the announcement is attached as Exhibit 99.1 to this Current Report on Form 8-K.
