Common use of Enforcement of Joint Patent Rights Clause in Contracts

Enforcement of Joint Patent Rights. If such infringement relates to the Joint Patent Rights, Alexion shall (unless such Joint Patent Rights relate only to a particular Product in a particular Future Indication as to which Alexion has Opted Out and not Opted Back In) have the first right, at its own cost and expense and in its sole discretion, to initiate, prosecute and control such legal action, or to control the defense of any declaratory judgment action for non-infringement relating thereto, including the right to settle any such action. If Alexion does not commence any such action within ninety (90) days after notice of such infringement, then XOMA will (unless such Joint Patent Rights relate only to a particular Product in a particular Future Indication as to which XOMA has Opted Out and not Opted Back In) have the right to either initiate and prosecute such action or to control the defense of such declaratory judgment action. Expenses under this Section 9.3(d) shall be shared 70 (Alexion)/30 (XOMA) between the Parties (except as set forth in Section 9.2(b)).
