The Athena decision is a notable addition to the growing body of case law governing the patent eligibility of diagnostic methods. The Supreme Court’s decision in Mayo Collaborative Services v. Prometheus Laboratories, Inc. has been the primary benchmark for assessing the eligibility of diagnostic methods. Since Mayo, however, the Federal Circuit has sought to clarify, in cases including Ariosa Diagnostics, Inc. v. Sequenom, Inc., Cleveland Clinic Found. v. True Health Diagnostics LLC, and now Athena, that claims reciting naturally occurring correlations “with no meaningful non-routine steps in between” will generally not be considered patent eligible. By contrast, claims that recite “new and improved” laboratory techniques, as in Rapid Litig. Mgmt. Ltd. v. CellzDirect, Inc., or a “novel method of treating a disease,” as in Vanda Pharm. Inc. v. West-Ward Pharm. International Ltd., will likely be considered patent-eligible. Whether claims fall on one side of this line or the other appears to depend heavily on whether the steps required to perform the method are either conventional and routine or new and improved.
The Athena decision is also notable because it reaffirms how the Federal Circuit analyzes diagnostic method claims. In particular, the Court continues to give significant weight to admissions in the patent specification about what was conventional, routine, and well-known. In Athena, the Court found that “the claimed advance was only in the discovery of a natural law,” and that “use of a man-made molecule [i.e., a radiolabeled antibody-antigen complex] in a method claim employing standard techniques [e.g., iodination and immunoprecipitation] to detect or observe a natural law may still leave the claim directed to a natural law.” Thus, as in other facets of patent law, an admission in the specification is likely to trump other evidence about the state of the art. Athena thus confirms that specifications, especially those involving this subject matter, should avoid making admissions that would jeopardize eligibility down the road.
As a procedural matter, the Federal Circuit disagreed with Athena that the district court erred by declining to consider its expert declaration about what was conventional at the time. Athena submitted the declaration in opposition to Mayo’s motion to dismiss. As clarified by the Federal Circuit in Aatrix Software, Inc. v. Green Shades Software, Inc., however, on a motion to dismiss (as distinct from a motion for summary judgment), factual allegations that a court must presume to be true in favor of the non-moving party must be pleaded in the complaint. While documents like the patent “merg[e] into the pleadings,” expert declarations and the like do not. Therefore, as a practical matter, patentees seeking to leverage a factual dispute to defeat a motion to dismiss must be diligent about pleading the necessary facts in their complaint or else succeed in converting the motion into one for summary judgment. Only in the latter will courts consider matters outside of the pleadings under the elevated standards applicable to summary judgment.
