In an attempt to broaden a patent’s disclosure and provide Section 112 support for features that are not explicitly disclosed within the patent’s specification (such as reagents, assays, techniques, etc.), patent applications are often drafted with boilerplate language to indicate that other “conventional,” “well-known” or “routine” features may be used. But acknowledging that features of a claimed invention are conventional, well-known or routine can be detrimental to patentability. Take the Federal Circuit’s recent decision in CareDx, Inc. v. Natera, Inc., for example, in which the court held that methods for detecting organ transplant rejection were directed to “a natural law together with conventional steps to detect or quantify the manifestation of that law.” (CareDx, Inc. v. Natera, Inc., No. 2022-1027, 2022 WL 2793597, at *8 (Fed. Cir. July 18, 2022).)
