23.           INFRINGEMENT

23.1         Licensee shall have the right during the term of this Agreement to commence an action for infringement of the Patent Rights against any third party for any infringement occurring within the Field of Use, provided that Licensee shall provide CASE thirty (30) days’ prior written notice of such infringement and of Licensee’s intent to file such action.  CASE shall have the right at its own expense to appear in such action by counsel of its own selection.  If required by the jurisdictional laws of the forum that any such action be prosecuted in the name of the owner of the Patent Right, CASE shall voluntarily appear at Licensee’s expense; provided that if such appearance subjects CASE to any unrelated action or claim of a third party or Licensee in such jurisdiction, then CASE shall have the right to decline such appearance.  Settlement of any action brought by Licensee shall require the consent of CASE and Licensee, which neither shall unreasonably withhold from the other, and any settlement amount or recovery for damages shall be applied as follows: (i) first, to reimburse the parties for their expenses in connection with the litigation; and (ii) second, CASE shall receive compensation for the time of any CASE personnel involved in the action; and (iii) third, CASE shall receive [********] of any monies remaining.
