Joint Patents Except as otherwise provided in this Section 7.3(b), the JSC shall entrust one Party with the right and authority, to prosecute and maintain the Joint Patents on a worldwide basis at its sole discretion herein referred to as an “Entrusted Party” (subject to this Section 7.3(b)). The Entrusted Party shall provide the other party reasonable opportunity to review and comment on such prosecution efforts regarding such Joint Patents. The Entrusted Party shall provide the other party with a copy of material communications from any patent authority regarding such Joint Patents, and shall provide the other party with drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses. If one Party (the “First Party”) determines in its sole discretion to abandon or not maintain any Patent within the Joint Patents anywhere in the world, then such Party shall provide the other Party (the “Second Party”) with thirty (30) days’ prior written notice of such determination (or such longer period of time reasonably necessary to allow the other party to assume such responsibilities) and shall provide the Second Party with the opportunity to prosecute and maintain such Patent at the Second Party’s sole expense, and if the Second Party so requests, the First Party shall assign such Patent to the Second Party (if the Second Party is Rhizen, such Patent shall be included in the Rhizen Patents or if the Second Party is TGTX, in which case such patent will be included in the TGTX Patents). If one Party (the “First Party”) desires to file, in a particular jurisdiction, a patent application that claims priority from a Patent within the Joint Patents, the First Party shall provide written notice to the other Party (the “Second Party”) of such desire. Within fifteen (15) days of such written notice, the Second Party shall provide written notice to the First Party as to whether the Second Party agrees to file a patent application in such jurisdiction or not. In the event the Second Party agrees to such a filing, the Entrusted Party shall file such patent application in such jurisdiction. In the event the Second Party does not desire to file in such jurisdiction, the Second Party shall (i) provide the First Party with the opportunity to file and prosecute such patent application and maintain any patent issuing therefrom, and (ii) assign such patent application or a right to file such patent application to the First Party; and the First Party may file such patent application in such jurisdiction at its sole expense (in which case such Patent shall be included in the respective Party’s Patents).
