Association For Molecular Pathology V Myriad GeneticsEdit
The Association for Molecular Pathology v. Myriad Genetics, Inc. is a landmark legal decision in the intersection of biology, technology, and private property. The dispute centered on whether formally isolating human genes—specifically BRCA1 and BRCA2, which are linked to hereditary breast and ovarian cancer—could be protected as intellectual property. The case brought together patients, physicians, researchers, and investors who argued that patent rights held by a private company impeded research and access to testing, while proponents of the patents stressed the importance of incentives for discovery and investment in healthcare technologies. The Supreme Court ruled that naturally occurring DNA sequences cannot be patented, while complementary DNA (cDNA), a lab-made copy that does not occur in nature, can be patentable. The decision reshaped the patent landscape for biotechnology, influencing how gene testing and other biotechnology innovations are developed and commercialized. It is a touchstone in debates over balancing intellectual property with public access to life-science advances and the costs and pace of medical innovation. See how the case sits at the crossroads of patent law and healthcare policy as well as the broader biotech ecosystem, including firms like Myriad Genetics and professional groups such as Association for Molecular Pathology.
Background
The dispute arose in an era when the biotechnology sector increasingly relied on patent protection to secure exclusive rights to gene sequences and related diagnostic methods. Myriad Genetics had secured patents on isolated DNA sequences corresponding to the BRCA1 and BRCA2 genes and on certain methods related to testing for hereditary cancer risk. Those patents granted Myriad exclusivity to certain tests and to the laboratory techniques used to identify variants in those genes, which in turn affected who could offer testing and at what price. Critics argued that patenting naturally occurring genes created monopolies over information that is biologically ubiquitous and clinically important, hindering independent research and patient access. Proponents contended that the patent system rewards long, costly, and uncertain investments in basic science and translational medicine, thereby fostering the development of diagnostic tools that otherwise might not be pursued.
The legal question focused on two core ideas. First, does the patent law allow claims on a DNA molecule that exists in the human body when it is isolated? Second, if such isolation is permitted, could the same legal framework cover artificially created DNA sequences that do not occur in nature, such as cDNA? The case also engaged broader doctrines about what counts as patentable subject matter under the longstanding Product of nature doctrine and the boundaries of invention in biology.
The case and ruling
The central holding of the Court was that items found in nature, such as isolated human DNA sequences, are not patentable merely because they have been isolated from the human genome. In other words, the mere discovery or isolation of a gene that already exists in the body does not meet the standard for invention that patent law requires. By contrast, cDNA—DNA synthesized from messenger RNA and not naturally occurring in that exact form—was deemed patentable because it is not a direct product of nature in the same way as the natural gene.
This distinction has concrete implications for the scope of protection a company can claim over diagnostic tests. Myriad’s claims to BRCA1 and BRCA2 DNA sequences in their isolated form were invalidated, but claims to certain cDNA sequences and to methods involving laboratory techniques could still be patent-eligible under the decision. The ruling thus struck a balance: it removed exclusivity over natural gene sequences while preserving incentives to innovate through patent protection for lab-made genetic constructs and methods.
The decision did not reject all traditional bases for patenting in biotechnology. It acknowledged that patents can play a role in encouraging discovery, but it insisted that the science of biology cannot be monopolized simply because a gene exists in nature. The case thus clarified how the patent system applies to biological materials and set a precedent for subsequent disputes about what qualifies as a product of invention versus a product of nature.

Implications for science, medicine, and markets
Access and competition: By removing patent protection on naturally occurring genes, the decision opened the field for broader participation in testing and research. Other laboratories can offer testing for BRCA-related risks without being blocked by exclusive rights on the gene itself, which can lead to lower prices and increased competition in the market for genetic testing and associated services.
Incentives for invention: The court retained a place for patent protections around non-natural DNA constructs and specific testing methods. This preserves incentives for scientists and companies to invest in developing synthetic sequences, novel assays, and improved diagnostic workflows, while avoiding the problematic monopolization of naturally occurring substances.
Research and development in biotechnology: Researchers could access natural gene sequences without facing prohibitive licensing terms, potentially accelerating discovery and verification of additional cancer-associated variants and other biomarkers. At the same time, firms can still pursue proprietary technologies, reagents, and process improvements that arise from human ingenuity and laboratory innovation.
Regulatory and policy considerations: The decision interacts with broader policy debates about how to regulate genetics research, how to balance patient access with incentives for innovation, and how to structure the patent system to reflect the realities of modern biotechnology.
From a market-oriented perspective, the ruling aligns with a core principle: property rights should reward genuine invention and non-natural enhancements, while not granting exclusive control over what is found in nature. This stance emphasizes efficient allocation of research resources, competition to reduce costs, and clearer boundaries between discovery and invention.
Controversies and debates
Critics of gene patents argued that granting rights to natural gene sequences creates broad, hard-to-challenge monopolies that can slow down scientific progress and limit patient access to testing. They contended that the public interest is best served by opening access to essential genetic information and the data generated from testing and research.
Proponents of patent protection in biotechnology emphasized that substantial investment, regulatory oversight, and long development cycles require legal protections to ensure continued funding for risky research. They claimed that the ability to secure exclusive rights on novel, non-natural aspects of testing—such as engineered sequences and unique assays—helps attract capital and support long-term projects.
The right-of-center perspective in debates around this case emphasizes the role of market competition and property rights in driving innovation and lowering costs for consumers. It tends to favor a framework that discourages broad, blanket monopolies over natural phenomena, while still protecting genuine inventions that require substantial effort and resources to develop. This viewpoint often argues that targeted protections for non-natural innovations and methods are appropriate, whereas attempts to patent natural products should be restricted.
Critics from other ideological angles sometimes argue that even the restricted patent framework can hamper collaborative research, slow the dissemination of knowledge, or favor well-capitalized firms over smaller players. In this vein, the discussion around woke critiques tends to focus on whether public policy should emphasize quick access and data sharing versus long-term incentives for innovation—arguments that the conservative-leaning analysis often frames as a matter of optimizing patient outcomes and market efficiency rather than symbolic policy signals.
The case remains a focal point for ongoing debate about how to structure incentives in high-cost areas like precision medicine. Supporters of the decision highlight that it preserves incentives for creating non-natural, human-made genetic tools while removing government-backed monopolies on natural biological information. Critics worry about potential unintended consequences for future diagnostic and therapeutic developments, arguing for careful calibration of protections to avoid dampening essential research.
