Multiple Assets and Licenses
The concept can be applied to baskets of assets and licenses; this makes RM more attractive to RM financers.
No Milestones, Only Royalties
Deals can be structured in such a way that certain milestones are not or only partly included in a RM deal if that fits other stakeholders' interest better.
No License But Revenues
If you do not have license deals but a predictable or growing revenue stream from one or more of your products, these can be monetized as well.
