The Myriad Case: The Gene Patent Fight Continues Technology Transfer Tactics Webinar October 4, 2012 Kevin E. Noonan, Ph.D. Patentable Subject Matter Under 35 U.S.C. 101: whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor… The Exception: “laws of nature, natural phenomenon, and abstract ideas are not patentable subject matter” Broad, subjective language that has resisted efforts to provide clear guidelines Creates uncertainty in prosecution and litigation AMP v. USPTO (“Myriad”) Myriad: The claims Two broad types of claims at issue: claims to isolated DNA molecules, and diagnostic method claims DNA claims recite “isolated” DNA encoding specific amino acid sequences (cDNA) Also claims to oligonucleotide probes Method claims: methods of detecting mutation or providing a diagnosis/risk assessment Method claims involve “comparing” mutant sequence to normal sequence 4 Myriad: The claims Composition of matter claims covering “isolated DNA” covering the BRCA 1 and BRCA 2 genes. Claim 1 of US Patent 5,747,282 is representative of this class of claims: An isolated DNA coding for a BRCA1 polypeptide, said polypeptide having the amino acid sequence set forth in SEQ ID NO:2. 5 Myriad: The claims Methods of detecting mutations in the BRCA genes. Claim 1 of US Patent 5,709,999 is the only claim in this class: A method for detecting a germline alteration in a BRCA1 gene, said alteration selected from the group consisting of the alterations set forth in Tables 12A, 14, 18 or 19 in a human which comprises analyzing a sequence of a BRCA1 gene or BRCA1 RNA from a human sample or analyzing a sequence of BRCA1 cDNA made from mRNA from said human sample with the proviso that said germline alteration is not a deletion of 4 nucleotides corresponding to base numbers 4184-4187 of SEQ ID NO:1 6 Isolated DNA claims “Isolated DNA” comes in two forms: genomic DNA and cDNA Significant differences in structure and how isolated/ prepared Is DNA a “product of nature”? Genomic DNA may be But chemically modified from native state cDNA certainly is not Claims limited to specific sequence that does not exist prior to human intervention District Court Decision Judge Sweet agrees that DNA an unpatentable “product of nature” DNA is “the physical embodiment of genetic information” Distinguishes other types of “natural products” (antibiotics, vitamins) on this basis Method claim invalid under Bilski 9 Gene Patenting Myths The Ownership Myth Michael Crichton, ACLU and “Who Owns You” The Information Myth “Physical Embodiment of Genetic Information” Information is not what’s patented “DNA is a chemical compound, albeit a complex one” Gene Patenting Myths The “Inhibits Research” Myth No evidence of research inhibition >9,000 science articles on BRCA genes Progress promoted by disclosure The “Natural Product” Myth Natural products not patent-ineligible per se Isolated DNA not found in nature cDNA not found in nature Gene Patenting Myths The “Didn’t Invent” Myth Ignores reality – plants as drug sources Antibiotics, antibodies, etc. The “Diagnostics” Myth Identifying mutation the first step Infrastructure costly to develop Research scientists vs. diagnostics laboratories Gene Patenting Myths Gene patents inhibit/prevent personalized medicine Genetic diagnostic methods (generally) do not infringe isolated DNA claims Unnecessary to isolate a gene to detect a mutation Diagnostic methods amenable to other forms of IP protection (e.g., trade secret) that are never disclosed (and hence can never be generic) A Clash of Cultures And traditional one: doctors vs. lawyers Another way to think about it: consumers vs. producers Ironically, many of the inventors are doctors and scientists, and many of the owners are universities Issues beyond patent law: access to medical care, First Amendment issues (access to medical information), ethics and morality Federal Circuit I Decision Federal Circuit reversed in 2011: Patent-ineligibility: diagnostic method claims – comparing/analyzing DNA sequences are abstract mental steps Patent-eligibility: screening method claims – screening therapeutics by measuring growth rates in transformed cells (which are not natural products) Method similar to the one the high court deemed unpatentable in Prometheus, except that it involves a cell that does not occur in nature. Patent-eligibility: composition of matter claims to oligonucleotides, genomic DNA and cDNA Federal Circuit I Decision (cont.) Method claims: claims reciting merely “analyzing” or “comparing” fail the “machine-or-transformation” test Claims to a screening method does not, since cell growth in presence of putative BRCA inhibitor is transformative Federal Circuit I: Majority Judge Lourie: “isolated DNA” patenteligible because it satisfies the Supreme Court “test” from Funk Brothers and Chakrabarty that a natural product can be patented provided that: there is “a change in the claimed composition's identity compared with what exists in nature” and “that human intervention has given ‘markedly different,’ or ‘distinctive,’ characteristics.” Chemical changes in isolated DNA enough Federal Circuit I: Concurrence Judge Moore: DNA a polymer, like nylon Isolated DNA not just purified from nature Also reads precedent as requiring alteration of natural product This rationale convincing for cDNA and oligonucleotide fragments because do not occur in nature – made by man Federal Circuit I: Concurrence “Isolated DNA” claims are a “closer case” Not entirely convinced that isolation effects sufficient change to satisfy precedent But, not “drawing on a blank canvas” cannot ignore 30 years of PTO practice and CAFC precedent (Amgen v. Chugai etc.) Change in the law up to Congress “Isolation” vs. “Purification” Both the majority opinion and Judge Moore’s concurring opinion set up a dichotomy “Isolated” DNA as claimed patenteligible because it has been chemically transformed Thus, DNA has not “merely” been isolated Implications for other biological molecule-based inventions Federal Circuit I: Dissent Judge Bryson: “common sense” conclusion that human DNA not patenteligible (including oligonucleotide primers) Applies the same Supreme Court precedent, comes to the opposite conclusion Concern seems to be negative effects on whole genome sequencing Discounts PTO practice and deference to Congress, citing DOJ position DOJ amicus brief On the one hand, the brief argues that manipulated DNA (cDNA, vectors, oligonucleotides, etc.) are patent-eligible because they show “the hand of man” On the other, isolated genomic DNA not patenteligible because it is not sufficiently changed Tries to “split the baby” by arguing on both sides of the issue Genetic diagnostic methods also patentineligible, since merely a “natural phenomena” Not from the Department of Commerce or the PTO and seemingly with little or no PTO input Myriad: DOJ brief Unfortunately, this does little to satisfy either constituency Worse, if this logic is accepted by the court the effects go far beyond DNA All biologic molecules, and many classical “products of nature” (antibiotics, antibodies, vitamins, hormones, enzymes, etc.) are essentially just “isolated,” often less changed than is isolated DNA Also, the goal of biologic drugs is to make the drug as similar to the “natural product” as possible Myriad Cert. Petition I Questions Presented: 1. Are human genes patentable? 2. Did the court of appeals err in adopting a new and inflexible rule, contrary to normal standing rules and this Court's decision in Medimmune, Inc. v. Genentech, Inc. . . . that petitioners who have been indisputably deterred by Myriad’s “active enforcement” of its patent rights nonetheless lack standing to challenge those patents absent evidence that they have been personally and directly threatened with an infringement action? Supreme Court GVR Supreme Court granted certiorari, vacated the Federal Circuit’s decision, and remanded for reconsideration in view of Mayo v. Prometheus Federal Circuit directed parties (and amici) to address “gene” claims and claim 20 (screening method claim) but not diagnostic claims Prometheus v. Mayo: Supreme Court Decision re: §101 • Patent claimed a method for optimizing treatment of an immune-mediated gastrointestinal disorder with 6thioguanine • Recited steps of administering the drug to a patient and detecting 6-thioguanine or 6-methyl-mercaptopurine (metabolite) in blood • Recited inferring step of therapeutic efficacy when 6thioguanine levels in red blood cells are between 230 pmol and 400 pmol per 8 x 108 red blood cells • Levels outside these ranges “indicates a need” to adjust administration amounts accordingly – but does not recite affirmative steps of adjusting Prometheus in the Federal Circuit • Steps for administering a drug and determining metabolites can be transformative and satisfy Bilski • Such steps can be “method of treatment” steps that are “always transformative” • Involving “natural processes” not determinative, since “every transformation of physical matter . . . occurs as the result of natural processes” • A process for chemical or physical transformation of a physical object or substance are “virtually self-evidently” patent-eligible subject matter • Inclusion of a mental step does not negate patenteligibility Question Before U.S. Supreme Court “This case concerns whether a patentee can monopolize basic, natural biological relationships. … The question presented is: Whether 35 U.S.C. § 101 is satisfied by a patent claim that covers observed correlations between blood test results and patient health, so that the claim effectively preempts all uses of the naturally occurring correlations, simply because well-known methods used to administer prescription drugs and test blood may involve ‘transformations’ of body chemistry.” Decision: not patentable • Court considers these claims to recite a law of nature “Beyond picking out the relevant audience, namely those who administer doses of thiopurine drugs, the claim simply tells doctors to: (1) measure (somehow) the current level of the relevant metabolite, (2) use particular (unpatentable) laws of nature (which the claim sets forth) to calculate the current toxicity/inefficacy limits, and (3) reconsider the drug dosage in light of the law.” “Routine, Conventional” • Basis: besides the law of nature, the claims merely recite “routine” or “conventional” steps “[T]he steps in the claimed processes (apart from the natural laws themselves) involve well-understood, routine, conventional activity previously engaged in by researchers in the field” “And since they are steps that must be taken in order to apply the laws in question, the effect is simply to tell doctors to apply the law somehow when treating their patients. “Not Enough” Added • Patent-eligibility requires something “more than” simply reciting a law of nature “To put the matter more succinctly, the claims inform a relevant audience about certain laws of nature; any additional steps consist of well understood, routine, conventional activity already engaged in by the scientific community; and those steps, when viewed as a whole, add nothing significant beyond the sum of their parts taken separately.” Natural Law not patentable • “Administration” step not relevant to patenteligibility “While it takes a human action (the administration of a thiopurine drug) to trigger a manifestation of this relation in a particular person, the relation itself exists in principle apart from any human action. The relation is a consequence of the ways in which thiopurine compounds are metabolized by the body—entirely natural processes. And so a patent that simply describes that relation sets forth a natural law.” Negative Consequences •The claims “tie up the doctor’s subsequent treatment decisions” •The claims “threaten to inhibit the development of more refined treatment recommendations (like that embodied in Mayo’s test), that combine Prometheus’ correlations with later discovered features of metabolites, human physiology or individual patient characteristics.” •”[U]pholding the patents would risk disproportionately tying up the use of the underlying natural laws, inhibiting their use in the making of further discoveries" Fed. Cir. Decision – Part II Substantially reiterated its previous decision in August 2012: claims to isolated human DNA satisfy the requirements of 35 U.S.C. 101. The Prometheus decision did not change the standards for assessing patent eligibility for compositions of matter previously set forth. Fed. Cir. Decision – Part II (cont.) Prometheus does not control the question of patent eligibility of Myriad's isolated DNA claims because they involve compositions of matter, rather than method claims. The majority: the claimed isolated DNA molecules are "not found in nature" and are "man-made, a product of human ingenuity.” Fed. Cir. Decision – Part II (cont.) Important distinction: characterizes the district court opinion as setting forth a “categorical rule” of patent-ineligibility, contrary to Bilski and Chakrabarty Specifically addresses the Supreme Court’s concern (in Mayo) regarding preemption, because compositions of matter are narrower in scope than claims to natural laws Federal Circuit II: Dissent Judge Bryson maintained his “common sense” objection to patenting human DNA not patent-eligible (including oligonucleotide primers) Now adheres to plaintiffs’ arguments that such claims “pre-empt” scientific efforts While finding Mayo ”instructive” also opines that it did not overturn Funk Bros. or Chakrabarty Myriad Cert. Petition II Filed Questions Presented: 1. Are human genes patentable? 2. Did the court of appeals err in upholding a method claim by Myriad that is irreconcilable with this Court's ruling in Mayo Collaborative Services v. Prometheus Labs, Inc.? 3. Did the court of appeals err in adopting a new and inflexible rule, contrary to normal standing rules and this Court's decision in Medimmune, Inc. v. Genentech, Inc. . . . that petitioners who have been indisputably deterred by Myriad’s “active enforcement” of its patent rights nonetheless lack standing to challenge those patents absent evidence that they have been personally and directly threatened with an infringement action? Some Hypotheticals to Ponder Are/should these be patentable: Isolated chemical compound from crude oil useful as a lubricant Isolated antibiotic produced by bacteria Isolated chemical compound from a plant useful as a drug Isolated protein from an animal useful to cure/ameliorate human disease Isolated cucumber gene that extends freshness Isolated Human gene (erythropoietin) Consequences and Recommendations Consequences of CAFC decision For now, “gene patents” claim patenteligible subject matter Practically, consensus decision on gene patent-eligibility for cDNA covers most patents on genes Isolated genomic DNA claims less certain, but less valuable Oligonucleotide claims more certain as man-made manufactures Consequences of CAFC decision Diagnostic method claims less certain Claims at issue flawed by claim language Interpreted to broadly encompass mere comparison of germline and patient BRCA gene sequences by inspection Claims do not recite affirmative steps for obtaining sequence Myriad has many other claims that do recite such steps Practical Implications From Myriad (and Prometheus) Neither decision as sweeping as it first looks Some diagnostic method claims are alive and well, provided they are claimed properly Gene patent claims are alive and well, however there is a risk that the Supreme Court could rule broadly and negatively for “naturally occurring” DNA (as opposed to cDNA) The key is to have “enough” more in the claims than simply “stating a natural law and then the words ‘apply it’”. Some Claim-drafting Strategies • Avoid claims that only produce information • Include active steps directing more than mental activity • Make sure the “law of nature” does not constitute the only novel feature of the claim Claim-drafting Strategies • General principles: - the more specific, the better - draft claims with active steps - consider “method of treatment” clams or steps when possible - remember who the infringer will be - include “unconventional limitations” Recommendations: Isolated DNA claims If “isolated” is insufficient, many DNA claims invalid Consequences depend on what the claims are protecting For making therapeutic proteins, recombinant cell claims should survive Vector claims should also be patentable (man-made) Kit claims should also be patentable, as manufactures 46 Recommendations: Patented technology “Narrowing” reissue a possibility For DNA claims, can limit to “manufactured” DNA – claim scope expressly outside chromosomal DNA by structure Can also narrow vector claims to these embodiments Diagnostic method claims to include “active” steps like sequencing 47 Recommendations: Patented technology In litigation, DNA claims not usefully asserted But then, what damage (usually) from DNA claim alone? Recombinant cells should survive Myriad even at Supreme Court Pharmaceutical infringement should involve at least use of recombinant cells 48 Claim-drafting Strategies: Prometheus A method of administering 6-thiopurine to a patient in need thereof for treating an immune-mediated gastrointestinal disorder, comprising the step of administering a therapeutically effective amount of the drug that produces no less than 230 pmol and no more than 400 pmol per 8x108 red blood cells in blood from the patient. Claim-drafting Strategies: Myriad A method for diagnosing a predisposition for breast cancer in a patient comprising the steps of: a) obtaining a biological sample from the patient; b) determining a sequence for BRCA1 or BRCA2 from the sample; c) detecting a breast cancer-related mutation in either BRCA1 or BRCA2 from the patient; and d) treating a patient having a breast cancer-related mutation with [effective drug such as taxol]. Natural Products Thought Experiment Researchers discover a molecule produced in humans that regulates blood pressure completely. It can replace all existing blood pressure medications and can be used in surgery, etc. to stabilize blood pressure. Remembering that the method of making something doesn’t itself render a molecule patent-eligible, is a perfect replica of this blood pressure regulator patent-eligible (regardless of how it is made)?
