Background Intellectual Property Notwithstanding and superseding anything to the contrary in this ARTICLE 14, each Party retains title to all Intellectual Property Rights owned or possessed by it or any of its affiliates prior to or independent of performance of this Agreement and used by it in fulfilling its obligations under this Agreement, as well as any modifications or improvements made thereto in the course of performing this Agreement (“Background IP”). To the extent that one Party acquires any right, title, or interest in and to any aspect of the modifications or improvements to the Background IP of the other Party, such first Party shall assign such right, title, and interest to the second Party, immediately following such acquisition. If any of the Supplier’s Background IP is included in or required to use the Documentation provided by the Supplier to the City, the Supplier hereby grants to the City an irrevocable, perpetual, fully paid-up, royalty-free, worldwide, transferable and non-exclusive licence (including the right to sub-licence only to members of the City’s Group) to, itself and through contractors and agents, use, copy, amend, reproduce, modify, create derivative works of, use, commercialize, and otherwise exploit the Supplier’s Background IP but only to the extent required to use such Documentation for the purpose (or any reasonably inferred purpose) for which it has been provided or for the provision of the Supply under this Agreement (excluding any software source code).
