Risk insight: Retaining IP in custom deliverables the Client funded is a major imbalance, made worse by the license being revocable. This is the top item to negotiate.
Safer rewrite: Deliverables created specifically for the Client under an SOW shall be 'work made for hire' and, to the extent they do not so qualify, Brightpath hereby assigns all right, title, and interest in such deliverables to the Client. Brightpath may retain ownership of pre-existing and general tools, granting the Client a perpetual, irrevocable license to any such materials embedded in the deliverables.
Law ref: 17 U.S.C. §101 (work made for hire)
Worst case: After the engagement, the Client cannot modify or migrate its own bespoke deliverables, and the vendor revokes the license during a fee dispute.
