Appeal 2007-0741 Application 09/313,625 estrogenic effects in others, depending on the particular SERM, the dose, the regimen, and the endogenous hormonal environment, we are not persuaded that one of ordinary skill in the art would have had a reason to superimpose a progestogenic compound on an anti-estrogenic compound. After all, as Young teaches, uterine bleeding is a frequent side-effect of combination estrogen-progestin therapy, despite the presence of the progestin. We find that the Examiner has not established a prima facie case that the claimed invention would have been obvious over the cited prior art, and we reverse the rejection of the claims under 35 U.S.C. § 103(a).
