The Wild, Wild West Of Laboratory Developed Tests, John Gilmore

Washington and Lee Law Review Online

Since the 1950’s, scientists have built novel technologies to screen for genetic diseases and other biological irregularities. Recently, researchers have developed a method called “liquid biopsy” (as opposed to a standard tissue biopsy) that uses a liquid sample (e.g., blood) to non‑invasively spot biomarkers indicating different types of cancers in the patient’s body. While the U.S. Food and Drug Administration (FDA) has fully cleared a small number of liquid biopsy tests under its rigorous and expensive review process, most biotech companies have instead followed a less restrictive regulatory path through the Centers for Medicare and Medicaid Services (CMS), which label …

The Impact Of Uncertainty Regarding Patent Eligible Subject Matter For Investment In U.S. Medical Diagnostic Technologies, A. Sasha Hoyt

Washington and Lee Law Review

Historically, 35 U.S.C. § 101, the statute governing patent eligible subject matter, has been construed broadly—with its legislative history indicating that it should cover “anything under the sun that is made by man.” The Supreme Court crafted three exceptions to § 101: (1) abstract ideas, (2) laws of nature, and (3) natural phenomena. In recent years, the Supreme Court’s eligibility jurisprudence has further narrowed § 101 to effectively exclude meritorious medical diagnostic methods. Indeed, since the Court’s decision in Mayo Collaborative Services v. Prometheus Laboratories, Inc., the Federal Circuit has held every single diagnostic method claim brought before it …

Patent Eligibility And Cancer Therapy, Christopher B. Seaman

Washington and Lee Law Review

As an empirical legal scholar, I am pleased to report that Sasha Hoyt has done what very few law students—and even many law professors—could achieve. She successfully conducted a novel empirical study to assess the real-world impact of a U.S. Supreme Court decision, Mayo Collaborative Services v. Prometheus Laboratories, Inc., on venture capital (VC) investment in startups and other companies that develop medical diagnostic technology.

As Ms. Hoyt notes, patent protection is particularly important for startup companies, as it can help protect their innovations from unauthorized use, attract funding and other investments, and foster collaboration with third parties. In …

Comment: On Patents And Appropriations—And Tragedies, David O. Taylor

Washington and Lee Law Review

I write to provide a few remarks concerning Sasha Hoyt’s illuminating work published in the pages of this journal. In it, Hoyt addresses the impact of the Supreme Court’s patent eligibility decisions on private investment in the development of medical diagnostic technologies. As an initial matter, I want to congratulate Hoyt for tackling an important topic. As Hoyt discusses, medical diagnostic technologies enable the diagnosis of diseases and other medical conditions such as genetic disorders, and early and accurate diagnosis may lead to early treatments and, ultimately, at least in some cases, saved lives. But the creation of medical diagnostic …
