I do not know what that was. But if so, that is an alternate hypothesis to 'they were lucky'--they may have derived indiplon in its final from the W-A group, and thus had to pay royalties, but it was not one that could have been specified in the Cyanamid patents. Perhaps I am not remembering this correctly, it comes from conversations last spring, and I have not checked my notes. You may have access to the chemical structures that may clarify this. But that's my understanding--and I do not have the chemistry acumen necessary to be definitive. 2) The GSK longterm preclinicals on the first CRF1 candidate are wrapping up or done--and the go-no go decision about proceeding ahead is going to come 1Q, I suspect on the early side. If there is some smoking gun problem, I havent heard anything, but I wouldnt expect to. There is a backup near-ready as well. 3) The question: If it is in fact so easy to devise an alternate time-release technology that does not infringe, but provides identical bioavailability and pharmacodynamics/kinetics (which could be very pertinent to clinical performance)--why would anyone bother patenting time-release technologies in the first place? I personally question whether it is in fact so simple (and free of infringement) to perfectly mimic a patented time-release formulation, and thus it may provide more protection than has been suggested here. Does this make sense to you given your chemistry expertise? Good night, Harry
