By Kevin E. Noonan —

Darwin, Mendel, Watson and Crick — a good case can be made that these four men make up the basis of modern biology as a science (as opposed to natural history).  As such, their contributions to human understanding, of ourselves and the natural world around us, will be remembered for the rest of human history.

The same, unfortunately, cannot be said for the amicus brief filed by Professor Watson (at right) in the Myriad case.  With the respect he is eminently due, the best that can be said is that he falls into many of the same legal, philosophical, and logical traps that others have on the subject (illustrating once again that genius rarely translates over distinct disciplines (Goethe and Count Rumford being exceptions) and that law, like science, can have subtleties that are not for the faint of heart or uninitiated.

Professor Watson makes three arguments, two of which are wrong and the third fraught with difficult consequences beyond his experience.  The first argument is that human genes should not be patented because DNA is a unique molecule different from other chemicals and should be treated as such; this is a variant of Judge Sweet's view that DNA is different because it is the "physical embodiment of genetic information."  While this characterization describes a gene's significance it does not change its fundamental nature as a chemical compound under patent law.  Fortunately, Professor Watson applies his argument only to human genes, which limits its applicability and potential for legal mischief.  However, the argument is a policy one outside the scope of the judiciary's purview.  Neither the Federal Circuit nor the Supreme Court has the role of making the types of policy decisions urged by Professor Watson in his brief.  This limitation was recognized by the Chief Justice in National Federation of Independent Businesses v. Sebelius (the healthcare case), where he stated "Members of this Court are vested with the authority to interpret the law; we possess neither the expertise nor the prerogative to make policy judgments.  Those decisions are entrusted to our Nation's elected leaders, who can be thrown out of office if the people disagree with them."  If U.S. patent law is to be changed to preclude patenting of isolated DNA molecules, this is a matter for Congress.  And it must be noted that Congressman Xavier Becerra has introduced several bills to do just that, and during Congresses actively engaged in patent reform.  But these bills have gone no where; indeed, even the portion of the Leahy-Smith America Invents Act having to do with patenting inventions comprising the human body (codifying the Weldon Amendment) were introduced and passed with assurance from its sponsors that the provisions were not intended to affect patenting of human DNA.

Professor Watson's second argument is that human genetic information should not be "controlled by legal monopolies" or the private property of any company.  Of course, a proper understanding of the matter is that human genetic information is not patented, and never has been.  All the DNA sequences in all the "gene patents" in all the world do not preclude an investigator from using the sequence information freely; indeed, insofar as the efforts of companies like Celera were actively involved in the Human Genome Project (and they were) and submitted patent applications containing human gene sequence information (and they did) these companies performed precisely the academic and scientific service Professor Watson espouses and the patent system promotes:  disclosure of the information to be used freely by others.  It is true, as Professor Watson writes, that some at the time (including Sir John Shulston and Professor Watson himself) thought patenting ill-advised.  But the inaccuracies regarding the effects of such patents evidenced by the brief and Professor Watson's apparent lack of experience with how biotechnology companies protect their intellectual property (and use it for funding) steal some of the force from these arguments.

The brief does raise a valid issue in its final portion:  the potential for the development of a "patent thicket" of sequences that could prevent easy commercialization of genetic diagnostics.  However, as frequently happens, the timeframe for robust genetic diagnostics (the future) and the timeframe for protecting human genes with patents (the past) are subject to shorter and shorter periods of overlap, so that the patents Professor Watson decries will not be in force when the genetic technologies are commercially available.  (There may be other patent impediments to be sure, but gene patents are not one of them.)  It is also the case that prototypical patent claims for human genes are simply not infringed by the types of genetic diagnostic testing that concerns Professor Watson in his brief (see the amicus brief filed by Dr. Holman, and the amici brief by Drs. Holman and Cook-Deegan).  And the remedy the Professor recommends, compulsory licensing, is simply inconsistent with the extent of investment that has been and can be expected to be required to actually get commercial embodiment of such test to patients, which is Professor Watson's professed purpose.

There is one portion of the brief, a footnote really, where Professor Watson sees clearly, and in a single sentence provides an apt synopsis for the sorry state of affairs that has led to this situation:

I have also read the Supreme Court's decision in Mayo v. Prometheus, although its opaqueness must leave many attorneys wondering if it adds anything at all to the issues of whether human genes ought to be patented.

Amen.

By Kevin E. Noonan —

Dr. Christopher Holman, Associate Professor of Law at the University of Missouri-Kansas City, filed an amicus curiae brief in AMP v. USPTO (the Myriad case) that addresses some of the factual and scientific inaccuracies that have been rampant in commentary and advocacy of this case at both the District Court and Federal Circuit, and within at least parts of the Executive Branch.

Dr. Holman (at right) makes three arguments:

I.  Isolated DNA is not simply DNA that has been cleaved and extracted from native chromosomal DNA

II.  The DNA of claims 1 and 2 of the '282 patent is not fundamentally different to an extent that would justify different patent eligibility

III.  There are several "unfounded assumptions":

a.  Regarding the utility of isolated genomic DNA

b.  As to the impact of isolated DNA patents on genetic testing and whole genome sequencing (WGS)

As an introduction, Dr. Holman discusses the "unusual posture" of the case, wherein there has been no allegation that "any particular technology infringes any of the challenged [composition of matter] claims [because, after all, the basis for standing in the case is that Myriad did threaten Dr. Harry Ostrer's former employer, New York University Medical Center, with a patent infringement lawsuit based on the method claims].  Dr. Holman reminds the Court that his own, independent research found "that no US court has addressed the question of whether an isolated DNA claim would be infringed by any form of DNA sequencing or diagnostic testing, citing his own paper in Science 322: 198-9 (2008) (see "Science Article Should Help Allay Gene Patenting Fears").  And he makes a point made previously, that "the claims [at issue] have yet to be adequately construed, and their purported preemptive effect remains entirely speculative."

Turning to his first argument, Dr. Holman references "[s]tatements in [the Federal Circuit's now-vacated earlier decision,] Myriad I, [that] suggest that some members of th[e] Court are under the impression that the claims encompass native genomic DNA that has been simply 'cleaved' from the chromosome and 'extracted' from the cell, in a process analogous to separating cotton fiber from cottonseed, or purifying human adrenaline from human tissue."  Dr. Holman quickly disabuses any members of the Court from this notion, reminding the Court that these conceptions are mere "imagery" that "might serve as a useful metaphor."  He also reminds the Court of a useless metaphor, the Department of Justice's "magic microscope," which he rightly characterizes as "misrepresent[ing] the biology and obscure[ing] the very real distinction between the claimed DNA and native chromosomal DNA."  Contrary to these simplistic misrepresentations, Dr. Holman construes the claims properly as being limited to "synthetic DNA molecules that are structurally and functionally distinguishable from their native counterparts."

Here, Dr. Holman makes a distinction opposite to, but in the same spirit as, Judge Sweet's attempt to separate DNA into its own category of biomolecule (albeit with much greater accuracy and less sophistry).  He ties the "fundamental[] differen[ce] between DNA and other biomolecules to their unique capacity to self-replicate.  Proteins and other biomolecules, not having any self-replicative capacity, must be separated from "other protein and cellular constituents, resulting in a purified preparation of protein molecules originating from a native source."  While this distinction is patently correct, it treads into the same dangerous waters as Judge Lourie's majority opinion in Myriad I, because in attempting to salvage patent-eligibility for DNA molecules it could lead to a determination that "merely" isolating a biomolecule is not enough (to use the Mayo v. Prometheus language) to render such other biomolecules patent eligible.  Here, Dr. Holman's brief goes on to explain the process by which a DNA molecule encoding a protein, like the BRCA1/2 molecules at issue here, is actually isolated (including the classical creation of a (entirely synthetic, man-made) genomic DNA library that is screened (again, an activity evincing the "hand of man") to identify and isolate the DNA molecule that can then be claimed.  For the uninitiated, and to illustrate how Dr. Holman eloquently explains a process that would require a description in excess of the 15-page amicus brief limit, that description is as follows:

A biologist seeking to isolate a human genomic gene begins by extracting chromosomal DNA from a sample of human cells, and then cleaving the long chromosomal DNA strands into shorter fragments.  These DNA fragments are then inserted into DNA vectors capable of replication in a host cell.  The vectors are subsequently introduced into cells, typically bacterial or yeast, which can be grown in culture.  The cells multiply, and as they do the recombinant vector DNA, including the fragment originating from the human chromosome, is replicated.

The resulting collection of vector-containing cells is referred to as a "genomic DNA library."  The cells comprising the library contain DNA that retains the primary sequence of genomic DNA, but the DNA molecules themselves did not originate in the human chromosome, but instead were synthesized as copies outside the body.  Single cells can be isolated from this mixture, and used to create a culture of cells that all comprise the same fragment of genomic DNA.  To isolate a gene of interest, a biologist screens the library to identify and isolate a pure cell culture that comprises a DNA fragment that includes the gene.

Once the DNA sequence of a gene has been determined, there is generally little reason to go back and repeat this process, since the sequence information of the DNA can be used to synthesize further copies by more convenient means.  For example, as described in a brief I submitted in the first iteration of this case, conventional BRCA genetic testing involves using techniques such as PCR to amplify DNA molecules representing fragments of a patient's full-length BRCA gene.  Brief of Amici Curiae Christopher M. Holman and Robert Cook-Deegan in Support of Neither Party, 2010 WL 4853323,*16.  In short, genetic testing does not involve cleaving the BRCA gene out of a native chromosome, but rather synthetic copies produced outside the body.

Dr. Holman then explains the relevance of this disquisition to the case at hand:  the isolation of the BRCA1 gene as described in U.S. Patent No. 5,747,282 (the '282 patent" employs the general methodologies described above," citing the appropriate portions of the '282 specification).  The process that was the focus of the inapt analogies by Plaintiffs and certain amici, isolating chromosomal DNA from a cell and cleaving that DNA into fragments, certainly occurred, Dr. Holman states, but "these are merely intermediate steps in the preparation of the genomic DNA library, from which the genes were actually isolated," and reminding the Court that said isolated and fragmented DNA preparation "would not [itself] fall within a reasonable construction of the claims."  In this he refutes the scientifically challenged argument that a "literal" reading of the claims would include such a fragmented chromosomal preparation (because it would "inherently include a BRCA gene") by reminding the Court that such an interpretation of the claim would clearly encompass the prior art.

Dr. Holman then cites additional distinctions between native DNA and the DNA as claimed:  that the isolated DNA has "distinct functional and structural characteristics," including epigenetics (such as DNA methylation) which is lost when DNA is isolated.

In his second argument, Dr. Holman challenges the government's argument that isolated genomic DNA and cDNA are "so fundamentally different . . . that the two forms of DNA should be treated differently for purposes of patent eligibility" as well as the appearance that members of the Court "have to some extent accepted this argument."  Dr. Holman states that the methods used to produce cDNA are "entirely analogous" to the methods he describes earlier in the brief for producing genomic DNA, and then once again explains for the Court how that is done:

As a first step, messenger RNA (mRNA) is extracted from human cells.  This collection of mRNA molecules will comprise many different sequences, generally representing all of the proteins that are being expressed by the cells.  The extracted mRNA is analogous to the extracted genomic DNA described above.  mRNA is structurally very similar to DNA, and contains the sequence information of the gene.  However, mRNA is a single-stranded molecule that cannot self-replicate like DNA and is less chemically stable.

To address these issues, scientists use the extracted mRNA molecules as templates to synthesize double-stranded cDNA molecules retaining the sequence information of mRNA, but which are more stable and can self-replicate.  These double-stranded cDNA molecules are inserted into vectors which are then introduced into cells, resulting in a cDNA library entirely analogous to a genomic DNA library as described above.  This library can be screened to isolate a cDNA corresponding to a gene of interest, e.g., a cDNA encoding a BRCA protein.

Significantly, the resulting isolated cDNA is entirely analogous to the claimed isolated genomic DNA.  In both cases the DNA did not actually originate in the cell, but it retains the informational content of a native polynucleotide sequence.  In the case of cDNA, the sequence of an mRNA molecule, and in the case of isolated genomic DNA, the sequence of genomic DNA.

While correct, it must be recognized that this explanation could just as easily be used as the basis for denying patent eligibility to cDNA as well as genomic DNA to those focused on the information content and blind to the chemical properties and characteristics Dr. Holman takes such pains to clearly explain.  This risk is exacerbated by Dr. Holman's argument that "a cDNA is nothing more than a rote copy of a naturally occurring mRNA molecule.  The 'engineering' to exclude introns and other regulatory regions is accomplished entirely within the cell, by natural processes, without any human intervention."  And in correcting some of the factually incorrect statements by Judge Moore in her concurring opinion (and taking several paragraphs of his limited space in the brief to explicate these errors), scientific correctness may have trumped effective advocacy.

Dr. Holman then discusses the "unfounded assumptions" that underlie the grounds in Myriad I for finding that the claimed DNA "had markedly different utility than its naturally occurring counterpart."  Here he again corrects Judge Moore's statements regarding the utility of isolated DNA for use as primers and probes, correctly stating that "the single most important category of biotechnology products" have been therapeutic proteins like erythropoietin and insulin, which required isolation of the human gene encoding them to enable production of sufficient quantities (using recombinant DNA technology) to be useful as the first biologic drugs.  However, Dr. Holman is entirely correct when he states that "[i]t would be unwise for the court to dismiss this important use of isolated DNA as insufficient to warrant patent eligibility, particularly when the parties who would most affected by this, biotechnology companies that produce biotech drugs (as well as patients that might benefit) are not parties to the litigation" (ironically, the BRCA-encoding DNA does not appear to have any such commercial utility).  In a further irony, Dr. Holman also corrects Judge Bryson's apprehension of the distinction between genomic and cDNA, that the latter can be "attached to a promoter and inserted into a non-human cell to drive protein expression," on the grounds that genomic DNA has the same utility (provided that the protein is made in a eukaryotic cell).

Finally, Dr. Holman discussed other "unfounded assumptions" relating to the impact of "gene patents" on genetic diagnostic testing and whole genome sequencing, focusing on the concerns in this regard contained in Judge Bryson's dissenting opinion in Myriad I.  Citing Judge Rich that "the name of the game is the claim," Dr. Holman challenges those "many critics of gene patents [who] incorrectly assume that any patent claim that recites a gene sequence necessarily forecloses any research or diagnosis relating to that gene."  Citing his earlier amicus brief with Dr. Robert Cook-Deegan, he again asserts that "there is no basis for assuming that all forms of DNA sequencing, especially next-generation single molecule methods, would necessarily entail the production of isolated DNA falling within the scope of the properly construed claims" and that "[c]laims reciting the full-length gene would not be infringed by conventional BRCA testing, for example, which is based on the amplification and analysis of fragments of the gene."  He concedes that the fragment claims are less certain in this regard, but reminds the Court that these claims may be invalid on other grounds (see "Caught in a Time Warp: The (In)validity of BRCA1 Oligonucleotide Claims").  He also challenges the assumption that progress in genetic testing will be impeded by "thousands of gene patents," citing his study (Holman, "Debunking the Myth That Whole Genome Sequencing Infringes Thousands of Gene Patents," 30 Nature Biotechnology 240 (2012)) debunking the oft-repeated and "widespread perception that 20% of human genes are patented," calling this "a myth based upon the misreading of a single 'Policy Perspective' article published in Science."

Dr. Holman's brief concludes with a most succinct and eloquent description of what is at stake in this case:

A determination by this court that any of the challenged isolated DNA claims is patent ineligible could cause serious unintended collateral damage to biotechnology, and should not be made cavalierly based on an overly simplistic and imprecise interpretation of the claims and speculation as to their potential preemptive effect.

By Donald Zuhn —

In its amicus brief filed in Association for Molecular Pathology v. U.S. Patent and Trademark Office ("Myriad"), the United States focuses solely on applicability of the Supreme Court's decision in Mayo Collaborative Services v. Prometheus Laboratories, Inc. on the patent eligibility of isolated genomic DNA.  The U.S. brief takes no position with respect to the impact of Mayo on Myriad's method claims (in particular, claim 20 of U.S. Patent No. 5,747,282), and concedes that "man-made complementary DNA molecules (cDNA) — which comprise nucleotide sequences that do not exist in nature — are patent-eligible subject matter under 35 U.S.C. § 101."

The brief notes, however, that "[a]s the United States explained in its original amicus brief, unlike cDNA, isolated but otherwise unmodified DNA molecules are not patent-eligible because they are 'products of nature,' not 'human-made inventions.'"  According to the U.S. brief, the Supreme Court's guidance in Mayo that "[p]atent protection is not available to those who simply discover existing aspects of nature, even if the discovery requires arduous work, represents keen scientific insight, and is of great value to society," simply "reinforces the conclusion that Myriad cannot patent DNA it discovered in and isolated from nature."

The brief characterizes the "principal issue" on appeal as being "whether composition claims for isolated genomic DNA are directed to patent-eligible subject matter," or worded another way, as "whether such claims are impermissible attempts to patent products of nature."  Citing Diamond v. Chakrabarty, the U.S. brief contends that "[t]o be eligible for a patent, a claimed composition must be 'human-made' and 'markedly different' from a naturally occurring substance."  The brief points out that the last time the Federal Circuit decided this case, "[t]he members of this panel agreed on that basic proposition," but "disagreed about whether distinctions between isolated and genomic DNA are significant enough to render isolated DNA 'markedly different' for § 101 purposes."

According to the U.S. brief:

The Supreme Court's decision in Mayo provides guidance regarding that question.  To be sure, that guidance is indirect.  Mayo involves process, not composition, claims, and the Court's analysis focuses on the standards for determining whether a claimed process effectively claims a law of nature.  Thus, Mayo does not directly address the criteria to be used in deciding the parameters of the product-of-nature exception, and every nuance of the Court's analysis may not mechanically extend to products of nature.  Nevertheless, in at least one respect, Mayo provides an important point of reference for deciding whether a claimed composition and a naturally occurring substance are "markedly different" for purposes of § 101.

In analyzing the claimed methods in Mayo, the Supreme Court repeatedly emphasized the need to ensure that claims not "tie up" laws of nature by preventing the public from exploring and exploiting those laws.

For the U.S government, "[t]he concerns implicated by patent claims that 't[ie] up the use of the underlying natural laws,' and thereby 'inhibit[] their use in the making of further discoveries,' may also be present when a patent contains a composition claim that relates to a product of nature."  The brief notes that "Mayo suggests that a court should ask whether a patent on the claimed composition has the practical effect of preempting the public's ability to use the product of nature itself."  The brief explains, therefore, that the genetically altered bacterium in Chakrabarty constituted patent eligible subject matter because it "would not have interfered with the public's ability to investigate or further modify the original bacterium or to experiment on the DNA plasmids that the patentee inserted into it to create the 'new bacterium.'"  "Similarly," the brief indicates, "cDNA molecules, which must be synthesized by scientists in the laboratory, are not created in the process of studying native DNA and pose little risk of preempting study of naturally occurring DNA."  The U.S, argues, however, that "patents on isolated but otherwise unmodified DNA would significantly impair the public's ability to study and make use of genomic DNA."

As for "Chakranbarty's 'markedly different' rubric," the brief disagrees with how the panel applied that standard in its first opinion, arguing that "[i]n light of Mayo, this Court should not rest patent-eligibility on the bare fact that isolating genes or gene segments involves the breaking of chemical bonds, or on the fact that scientists can use small gene segments to exploit the inherent chemical properties of DNA in ways that cannot be done with complete genes," and instead should ask "whether the differences identified in the original panel decision are sufficient to leave the public free to study and exploit the native BRCA1 and BRCA2 genes."

The U.S. brief concludes by briefly noting that the Supreme Court's refusal in Mayo to determine whether it was desirable to increase protection for discoveries concerning diagnostic laws of nature further illuminates the § 101 analysis.  The brief suggests that "[i]n this case, Myriad has argued that the extension of patent protection to isolated DNA is necessary in order to preserve financial incentives for making DNA discoveries."  The brief argues, however, that "Mayo strongly suggests that the judicial inquiry should not focus on industry-specific incentive arguments of this sort, pro or con, and instead should focus on 'established general legal rules.'"

By Donald Zuhn —

With oral argument in Association for Molecular Pathology v. U.S. Patent and Trademark Office ("Myriad") less than two weeks away, Patent Docs continues its examination of some of the twenty-three amicus briefs that have been filed in this case.  Today, we look at the amicus brief filed by the Intellectual Property Owners Association (IPO).  (For the sake of full disclosure, the IPO brief was co-authored by Patent Docs author Kevin Noonan.)

The IPO brief makes three arguments.  First, the brief argues that claims to isolated DNA molecules constitute patent eligible subject matter under 35 U.S.C. § 101; second, the brief contends that method claim 20 is patent eligible under § 101; and third, the brief asserts that a ban on the patenting of isolated DNA molecules and gene-based diagnostic screening methods would negatively impact innovation.

With respect to the first argument, the brief begins by pointing out that Supreme Court precedent supports the patent eligibility of isolated DNA, noting that:

The Supreme Court in [Diamond v.] Chakrabarty found no constitutional, philosophical, or jurisprudential infirmities in the choice by Congress to define patent eligible subject matter broadly.  Indeed, the Court cited Thomas Jefferson for the proposition that the patent laws should be broadly construed with regard to what is patent eligible, referencing the first Patent Act of 1793 and Jefferson’s exhortation that "ingenuity should receive a liberal encouragement."  Id. (quoting 5 Writings of Thomas Jefferson 75-76 (Washington ed. 1871)) (citing Act of Feb. 21, 1793, § 1, 1 Stat. 319).

While acknowledging that "[t]he Court recognized that the scope of patent-eligible subject matter was not infinite," the brief notes that "the Court was parsimonious in setting forth what was not patent eligible: 'laws of nature, physical phenomena, and abstract ideas.'"  According to the brief:

The Court fashioned a straightforward test of whether a manufacture or composition of matter was patent eligible:  it must demonstrate the "hand of man," something that is "a product of human ingenuity 'having a distinctive name, character [and] use.'"  Id. at 309–10 (quoting Hartranft v. Wiegmann, 121 U.S. 609, 615 (1887)).

Asserting that "any manufacture or composition of matter evincing the 'hand of man' should be patent eligible," the brief argues that isolated human DNA is patent eligible because it evinces the hand of man.  In particular, the brief explains that:

Isolated human cDNA is a manufacture under the Patent Act because it is made by enzymatically-generating copies of cellular messenger RNA (mRNA).  In manufacturing isolated DNA, an inventor must identify a cell that expresses a gene, isolate the mRNA and enzymatically convert the mRNA into DNA.  The enzymatic conversion is performed by a viral enzyme called reverse transcriptase that is absent from cells that have not been intentionally infected by a virus that produces the enzyme.  Significantly, cDNA copies of mRNAs encoding isolated human DNA do not exist without human intervention.

The brief also argues that "[a]s a consequence of the intervention of the 'hand of man' in isolating the claimed DNA, the manufactured DNA has uses not shared with naturally occurring DNA (for example, as genetic probes and for producing useful quantities of proteins encoded by the DNA)," and therefore contends that the "claimed DNA . . . becomes 'a product of human ingenuity 'having a distinctive name, character [and] use.'"

The IPO brief also points out that the Supreme Court did not overrule Chakrabarty in Mayo Collaborative Services v. Prometheus Laboratories, Inc., but rather cited that case with approval.  In addition, the brief notes that among the concerns cited by the Mayo Court was that certain claims might inhibit future innovation.  The brief counters that:

These concerns do not apply to Myriad's DNA claims because the information content of DNA is not patented.  Myriad's claims are limited to chemical compounds, the isolated DNA molecules themselves.  The genetic information contained within naturally occurring DNA — the sequence of the A, T, C, and G nucleotides — does not fall within the scope of these claims.

Moreover, the IPO brief argues that "Myriad's DNA claims have not had any negative effects on technological development, another concern of the Supreme Court in Mayo," noting that "a cursory scan of the medical and scientific literature reveals more than eight thousand articles and reports regarding human BRCA 1 and BRCA 2 genes since the patents-in-suit were granted."

With respect to Myriad's method claim 20, the IPO brief argues that this claim is "directly analogous" to the method claim that was upheld by the Supreme Court in Diamond v. Diehr.  In particular, the brief contends that "[w]hen considered as a whole, claim 20 should be patent eligible because it is directed to a specific drug screening process that employs an altered form of the BRCA1 gene and does not preempt other uses of the naturally occurring BRCA1 gene."

The IPO brief concludes by asserting that a ban on the patenting of isolated DNA molecules and gene-based diagnostic screening methods would negatively impact innovation.  The brief argues that "[i]f the possibility of patent protection is removed, innovation in genetic-based diagnostics would be harmed," suggesting that "[t]here would be no incentive (indeed, there would be strong disincentives) to disclose the genetic basis of complex diagnostic assays."  The brief also predicts that:

[T]he impact of affirming the district court's decision is not limited to isolated human DNA or medical and pharmaceutical applications thereof.  Many other fields, including industrial biotechnologies involving alternative fuels, industrial biochemicals, and genetically modified foods, would be harmed because these industries have depended for decades on patent protection for isolated DNA inventions from non-human organisms.

Patent Docs will examine other amicus briefs as the date of oral argument in Myriad approaches.  In addition, we will be updating our list of briefs filed in the case later this week.
