That XOMA gets some royalty from DNA on Lucentis has been disclosed; I was looking for a quantitative assessment of the royalty
Don't quote me on this but I thought I heard on one of the calls an analyst talking as if 1% was the royalty and not being disputed. This is going from memory. Here is a quote from a PR would seem to be consistent too. Sorry don't know the x-US portion of your question.
"Royalty percentages on BCE licenses range from 0.5% to 3% of net sales, and the royalty on LUCENTIS(tm) is toward the lower end of this range."
