The Value Of Pharmaceutical Method Claims

The Federal Circuit’s Myriad Genetics decision, Ass’n for Molecular Pathology v. U.S. Patent and Trademark Office, 99 U.S.P.Q. 2d 1938 (Fed. Cir. 2011), which invalidated most of the method claims in the patents at issue, brings to mind a concern about the value of method claims, particularly to the pharmaceutical industry. The Myriad Genetics patents at issue included two types of method claims relating to human genetics: one involved determining whether a female patient had abnormal BRCA1/2 genes by comparison of BRCA1/2 gene and BRCA 1/2 RNA from the patient’s tumor sample to those from a non-tumor sample; the second was an activity screening method for anticancer drugs that compared the growth of a host cell transformed with a cancer-causing BRCA gene in the presence and absence, respectively, of the test compound.
