R&D partnerships are a long way from "coming of age" (March). Your story led off with a photo of the De Lorean automobile, which was financed partly through an R&D partnership. De Lorean is now in serious financial straits, and I doubt if the R&D investors will get any return on their investment soon, if ever.
As the De Lorean case indicates, there will be substantial shakeouts in the R&D limited partnership business before it ever settles down and "comes of age" as real estate or oil and gas partnerships have. R&D partnerships are a high-risk game that is being heavily promoted and has yet to be proven. Yes, some have made money in R&D partnerships, but so far, those who have are mainly promoters.
