In the oligosaccharide characterization territory I don't think Teva has experts like Ganesh Venkataraman and Ram Sasisekharan nor some "hidden magical" IP. I believe what Teva has done and can do is use all known techniques and tools to conducts the analysis. The one thing Roy, Jim and myself once thought could make a difference was when Teva has signed an agreement with Procognia under which Teva gained access to Procognia's proprietary glycoanalysis technology, but after digging there I've posted this isn't a possibility.
