George - If the company was static they, Zack's may be wrong about the R&D costs. The RVX IP library is continually expanding so continuos spending on R&D should be expected. This IP expansion could continue for many years with access to lots of capital. It is quite possible that their R&D spend could be dramatically higher if the funding was available. There is a boat load of science to be followed up on in this company.
It is my opinion that the winning bidder for RVX will have many many years of new products to bring to the market with science inside this company.
