ExxonMobil has the unencumbered right to file or not to file, prosecute, defend, maintain, abandon, or enforce any Program Invention or Program Patent. Notwithstanding the foregoing, in the event ExxonMobil decides not to prosecute, defend, enforce, maintain or decides to abandon any Program Patent, then ExxonMobil will provide notice thereof to FCE, and FCE will then have the right, but not the obligation, to prosecute or maintain the Program Patent and sole responsibility for the continuing costs, taxes, legal fees, maintenance fees and other fees associated with that Program Patent. The ownership of such Program Patent will remain with ExxonMobil. The abandonment of a pending patent application in favor of a continuation patent application, continuation-in-part patent application, or divisional patent application, or in favor of another application of a related subject (e.g. to overcome a double patenting rejection) and ExxonMobil's decision not to file any Program Patent, will not be deemed to be an election not to continue to prosecute, issue, or maintain any Program Patent under Paragraph 6.04. In addition, (a) the failure to appeal a patent office or any administrative tribunal or judicial decision adverse to any patent or patent application, or (b) in the case of a co-pending non-provisional application in the U.S., (i) failure to enter an international patent application into the national phase, or (ii) to ratify a patent in any country, will not be deemed to be an election not to continue to prosecute, issue, or maintain any Program Patent under Paragraph 6.04. 6.06 Joint Research Agreement. The Parties acknowledge and agree that this Agreement is a "joint research agreement" as defined in 35 U.S.C. §100(h). The specification of any patent application filed pursuant to this Agreement may contain (or may be amended to contain) language required to invoke 35 U.S.C. §102(b)(2)(C) and §102(c) as applicable. Notwithstanding anything to the contrary in Paragraph 5.01 (Publicity), ExxonMobil will have the right to invoke these statutory provisions when exercising its rights to file patent applications under this Agreement, without the prior written consent of FCE, subject to the provisions of Paragraph 6.02 (Solicitation of Program Patents). Where ExxonMobil intends to invoke these statutory provisions, FCE, upon request, will cooperate and coordinate its activities with ExxonMobil with respect to any submissions, filings or other activities in support thereof. 6.07 Inventor Awards. A Party will not be responsible for any inventor awards or compensation that may be owed to the other Party's employee(s) or to any employees of the other Party's Affiliates, agents, consultants, or contractors, who are inventors of any Program Invention. 6.08 Disposal of Prior JDA Project Patents. During the Term of this Agreement and for two (2) years thereafter, in the event that either Party decides to sell or convey its interest in or otherwise dispose of any Prior JDA Project Patent to any Non-Affiliated Third Party, such Party will inform the other Party, who will then have the right of first refusal to purchase or otherwise acquire the sole interest at same or better terms. Any sale of a Prior JDA Project Patent to a Non-Affiliated Third Party is subject to the licenses granted and other obligations set forth in this Agreement. ARTICLE 7 - LICENSE TO PROGRAM RESULTS 7.01 Grants to FCE of Program Results. (a) FCE's R&D Rights. ExxonMobil grants FCE a worldwide, non-exclusive, royalty-free, non-transferable (except pursuant to Article 14 (Assignment)), non-sub-licensable (except as set forth in this Paragraph 7.01(a)) right and license to practice Program Results solely to conduct research and development for the Program. More particularly, said right and license to practice includes the right to use, reproduce, and create derivative works of Program Information under applicable copyrights and to make, use, and import (but not sell or offer to sell) under the claims of Program Patents, in each case solely for research and development for the Program. Said right and license may be extended to contractors performing work on behalf of FCE but is not otherwise sub-licensable.
