Common use of Celgene Clause in Contracts

Celgene. As between the Parties (including their respective Affiliates), Celgene (or its Affiliate) will retain all right, title and interest in and to all Celgene IP, except as otherwise expressly set forth herein, including all rights to Prosecute and Maintain, and enforce any such Celgene IP, and no rights or licenses are granted to Prothena hereunder with respect to any Celgene IP except as expressly provided in Section 7.2. In the event that Prothena desires to utilize any Celgene IP not subject to Section 7.2 for the performance of a Program, then Prothena may request such right in writing from Celgene (which writing shall identify the particular Celgene IP that Prothena would like to use), and if Celgene agrees, in its sole discretion, the Parties shall negotiate and enter into a separate agreement setting for the terms and conditions under which Prothena may utilize such Celgene IP.
