    PDL BioPharma Synagis Patent Invalidated

    Medimmune #1 MedImmune gained major ground in its infringement and licensing dispute with PDL BioPharma after its last patent on antibodies used in the respiratory drug Synagis was found invalid.  The relationship between the parties began in 1997, when PDL granted MedImmune a license to develop certain types of antibodies covered by five PDL patents.  In 1998, MedImmune received approval from the FDA to market the antibody drug Synagis, which is used to prevent lower respiratory tract disease in infants and children.  In December 2008, in a complaint filed in the U.S. District Court for the Northern District of California, MedImmune asked for a declaratory judgment that the five PDL patents covering the antibodies were invalid, and that it owed no payments to PDL under a patent license agreement reached by the companies.  PDL argued that the patents were valid and that MedImmune's antibody treatments infringed those patents.  Leading up to the latest ruling in the case, only a single claim of one patent (U.S. Patent No. 6,180,370) remained at issue, which MedImmune claimed was invalid and which PDL claimed covered Synagis.  Recently, MedImmune moved for summary judgment of invalidity, and PDL moved for summary judgment with respect to MedImmune's restitution claim regarding the patent royalties paid.

    PDL BioPharma On January 7, Judge Fogel granted MedImmune's motion for summary judgment, thus invalidating claim 28, the sole claim at issue in the case.  Judge Fogel found that the claim was anticipated by U.S. Patent No. 6,548,640, which covered the composition claim for a class of humanized immunoglobulins.  As a consequence, the Court held that MedImmune did not violate the licensing agreement.  MedImmune also prevailed with respect to PDL’s fraud counterclaims.  PDL did receive some good news, however, when the Court determined that it did not have to return $42 million in royalties MedImmune paid on a European patent that was invalidated in 2005.  Judge Fogel saved the final licensing agreement issue for a jury.  Judge Fogel’s order can be found here.


    Novo's Prandin Patent Found Invalid

    Novo Nordisk Despite the efforts Novo Nordisk has spent over the past five years defending and enforcing U.S. Patent No. 6,677,358, which covers Prandin, the '358 patent has been found invalid for obviousness and not enforceable due to inequitable conduct.  Novo originally filed suit against Caraco in 2005 in the U.S. District Court for the Eastern District of Michigan, alleging infringement of the '358 patent based on Caraco's ANDA for a generic version of Prandin.  Caraco counterclaimed that Novo's patent was invalid and would not be infringed by the sale of its generic version of the drug.  In 2007, the FDA notified Caraco that it could not grant final approval of the ANDA because of the Novo lawsuit.  Caraco then amended its ANDA with a Section VIII statement, but Caraco's claim was rendered moot when the FDA allowed Novo to modify the use code of the '358 patent to include a claimed method.  Novo's request for a change of its use code was contested and appealed to the Federal Circuit, which ultimately ruled in April that the change was permissible (see "Novo Nordisk A/S v. Caraco Pharmaceutical Laboratories, Ltd. (Fed. Cir. 2010)").  In July, the Federal Circuit denied an en banc rehearing of the case.  There was then a trial, extending over 11 days in June and August of 2010.

    Caraco Pharmaceutical Laboratories On January 19, in a detailed opinion, Judge Cohn found that the ‘358 patent is not invalid because of anticipation, but is invalid because of obviousness, and is not enforceable because of inequitable conduct.  The Court looked closely at all the prior art, finding that the record clearly establishes that the prior art supplied the teaching, suggestion, and motivation to combine repaglinide with metformin as a combination therapy for Type II diabetes.  Novo presented evidence of secondary considerations, particularly unexpected results and commercial success, but those were not found persuasive enough to overcome the prima facie case.  Turning to inequitable conduct, Judge Cohn found that an incomplete declaration and withholding of information during patent prosecution was a violation of Novo's duty of disclosure, thus exceeding the necessary threshold levels of materiality and intent.  As such, Judge Cohn concluded that the patent cannot be sustained.  Judge Cohn’s opinion can be found here, and his judgment can be found here.


    Aurobindo Pharma Settles with Wyeth in Effexor XR Litigation

    Aurobindo Aurobindo Pharma and Wyeth have settled their patent dispute over Aurobindo's generic version of the antidepressant Effexor.  In April, Wyeth brought suit in the U.S. District Court for the District of New Jersey, claiming that Aurobindo's plan to market its own generic version of Effexor XR infringed U.S. Patent Nos. 6,274,171; 6,403,120; and 6,419,958.  The three patents, which were issued between August 2001 and July 2002 and subsequently assigned to Wyeth, cover an extended release formulation of the drug's active ingredient venlafaxine hydrochloride.

    Wyeth On January 6, Judge Freda L. Wolfson signed off on the parties' dismissal of the dispute without prejudice.  The order preserved the right to reopen the action within 60 days if the proposed settlement is not consummated.  Additional details of the dismissal were not disclosed.  Judge Wolfson's order can be found here.

    Latta, Robert Last fall, Rep. Robert Latta (R-OH) (at right) introduced legislation in the House (H.R. 6352) that would have amended 35 U.S.C. § 292 to modify the penalty for false marking (see "New False Marking Bill Introduced in the House").  On January 7, Rep. Latta reintroduced the bill, now H.R. 243, in the House.  The legislation, entitled the "Patent Lawsuit Reform Act of 2011," would revise section 292 as follows (with changes indicated by underlining and italics):

    (a)  . . .  Whoever marks upon, or affixes to, or uses in advertising in connection with unpatented articles the word "patent" or any word or number importing the same is patented, for the purpose of deceiving the public; or

    Whoever marks upon, or affixes to, or uses in advertising in connection with one or more articles the words "patent applied for," "patent pending," or any word importing that an application for patent has been made, when no application for patent has been made, or if made, is not pending, for the purpose of deceiv­ing the public —

    Shall be fined not more than $500, in the aggregate, for all offenses in connection with such articles.

    (b)  A person who has suffered a competitive injury as a result of a violation of this section may bring a civil action in the appropriate district court of the United States against the person violating this section for recovery of not more than $500 in damages to compensate for the injury.

    Section 292 currently provides, in part, that:

    (a)  . . .  Whoever marks upon, or affixes to, or uses in advertising in connection with any unpatented article the word "patent" or any word or number importing the same is patented, for the purpose of deceiving the public; or

    Whoever marks upon, or affixes to, or uses in advertising in connection with any article the words "patent applied for," "patent pending," or any word importing that an application for patent has been made, when no application for patent has been made, or if made, is not pending, for the purpose of deceiv­ing the public —

    Shall be fined not more than $500 for every such offense.

    (b)  Any person may sue for the penalty, in which event one-half shall go to the person suing and the other to the use of the United States.

    Rep. Latta's new bill is identical to the legislation he introduced in October.  After introducing H.R. 6352, Rep. Latta indicated that the bill, if enacted, "would strengthen the vague language [of § 292] to revert back to the pre-Forest Group [v. Bon Tool Co.] decision and assess one $500 fine if found guilty of deceiving the public under Section 292 and not allow for the interpretation of being fined for each product on the market."  Rep. Latta's bill would also require an individual bringing a false patent marking suit to have suffered a competitive injury as a result of the violation.  Last fall, Rep. Latta said that the "legislation is now needed to help companies fend off frivolous lawsuits and strengthen current law."

    In addition to Rep. Latta's bill, Rep. Darrell Issa (R-CA) is believed to be preparing to reintroduce his own false patent marking bill, which was originally introduced in March 2010 (see "False Patent Marking Bill Introduced in the House").  Like Rep. Latta's bill, Rep. Issa's bill is expected to require an individual bringing a false patent marking suit to have suffered a competitive injury as a result of the violation.

    An enduring trope in literature from all civilizations is the efforts of one generation to make conditions and prospects better for the next generation.  That parents care for their children has been explained as "human nature," sound economics, or biologically determined altruism (thereby extending the lifespan of one-half of one's genes in each child).  A different question is to what extent are existing members of a polity willing to sacrifice not only for their own children but for a more disembodied "posterity," particularly when the sacrifices required are related to healthcare costs in the present and the benefits are (perhaps) better healthcare in the future.

    Cover This is the question raised in a provocative paper published in Health Affairs entitled "The Benefits from Giving Makers of Conventional 'Small Molecule' Drugs Longer Exclusivity over Clinical Trial Data."  The authors include Dana P. Goldman, Norman Topping Chair in Medicine and Public Policy, Director of the Leonard D. Schaeffer Center for Health and Economics, University of Southern California; Darius N. Lakdawalla, Associate Professor, School of Policy, Planning and Development, Director of Research, Leonard D. Schaeffer Center for Health and Economics, University of Southern California; Jesse D. Malkin, Consultant, Precision Health Economics, Santa Monica, CA; John Romley, Research Assistant Professor, School of Policy, Planning and Development, University of Southern California; and Tomas Philipson, Daniel Levin Professor of Public Policy Studies, Irving B. Harris Graduate School of Public Policy Studies, University of Chicago.  Their conclusion:  that extending "data exclusivity" for conventional "small molecule" drugs from the present 5 years under the Hatch-Waxman Act to 12 years (the term given biologic drugs under the Affordable Care Act of 2010) would provide a net benefit in new drugs and increased longevity, not for ourselves but for our grandchildren.

    The authors note that this idea is not new:  Europe gives ten years of data exclusivity for both conventional and biologic drugs, and the National Academy of Science, Committee on Science, Engineering and Public Policy recommended that the U.S. adopt the European term (National Academies Committee on Science, Engineering, and Public Policy, Institute of Medicine, "Rising Above The Gathering Storm: Energizing and Employing America for a Brighter Economic Future," Washington (DC): National Academies Press; 2007).  This study also suggested that research be funded to ascertain whether ten years of data exclusivity was long enough "given the complexity and length of drug development today."  The authors' thesis is that data exclusivity term length "entails a trade-off between current and future generations" because a longer term causes drug prices to rise in the short term but promotes "a stronger incentive to innovate" in innovator drug companies, which provides benefits in the future.  "Although some have questioned whether profits drive innovation, empirical evidence strongly supports this relationship," the authors assert, citing the increase in pharmaceutical development after passage of the Orphan Drug Act in 1983 (Lichtenberg & Waldfogel, 2003, "Does misery love company? Evidence from pharmaceutical markets before and after the Orphan Drug Act," Cambridge (MA): National Bureau of Economic Research; 2003. NBER Working Paper No.: 9750) and stimulus of vaccine production that accompanies higher profits for vaccine-makers (Finkelstein, 2004, "Static and dynamic effects of health policy: evidence from the vaccine industry," Q J Econ. 119: 527–64).  According to a study by Acemolglu and Linn published in Quarterly Journal of Economics in 2004, "a 1 percent increase in the potential market size for a drug class leads to a 3-4 percent growth in the entry [into the marketplace] of new drugs (Acemoglu & Linn, 2004, "Market size in innovation: theory and evidence from the pharmaceutical industry," Q J Econ. 119: 1049–90)."  This incentive can be quantified, the authors assert, so that one additional drug would be expected to be produced for each additional $97.5 million in annual revenue.  This represents a 12% return on the average $800 million investment required to bring a new drug to market.

    The authors address the question of what are the effects on longer data exclusivity terms for small molecule drugs on both "present [higher drug costs] and future [more new drugs] generations."  Specifically, 1) "[h]ow would  extending the initial five years of data exclusivity for new conventional drugs in the United States affect innovation?" 2) "[h]ow would a longer period of data exclusivity affect the health of current and future generations?" 3) "[w}hat is the dollar value of a longer period of data exclusivity to US society?"

    The authors perform their analysis by estimating the increase revenues to innovator drug companies that would accrue if the data exclusivity period was extended from 5 years to 12 years, using "retrospective data from the drugs@FDA database."  These results  were then analyzed in the authors "global pharmaceutical policy model" (Lakdawalla et al., 2008, "US pharmaceutical policy in a global marketplace. Health Aff. (Millwood). 28(1): w138–50) to determine "the effect of increased pharmaceutical revenues on drug innovation and consumers' longevity."  The authors make some explicit assumptions:  that "next year's health status depends on today's health"; that the "social discount rate" (i.e., how "society discounts benefits in the future compared with benefits today") is 3 percent; and that the "innovation elasticity" is 3.0 (i.e., that "a 1 percent increase in expected drug revenue leads to a 3 percent increase in the number of drugs approved within [a drug] class each year").  Their model also assumes that "increased innovation . . . affects population health," wherein drug innovation leads to new drugs, which leads to a greater likelihood of treatment and greater life expectancy, which results in a greater population of potential drug users, which further increases drug revenue and stimulates further innovation.  Finally, while acknowledging that "[t]he monetary value of increased longevity . . . has long been a subject of debate," the authors assumed "a monetary value of increased longevity of $200,000 per life-year."

    The authors also recognize limitations in their analysis, including differences between conditions existing during creation of the retrospective data and future changes in "laws, regulations, science and medicine" such as increases in successful drug patent challenges, government price controls and unforeseen advances (or setbacks) in medical science.  Also not considered (due to its inherent "complexity") are changes in generic drug manufacturer behavior (such as those companies conducting independent clinical trials) or the effects of "nonmortality benefits" such as mental health or pain.

    Their results show that "extending data exclusivity to twelve years would increase lifetime drug revenues by 5 percent (average)" (see Goldman et al., 2011, Exhibit 1 below; click on image to expand).

    Exhibit 1 On average innovator drugs face generic competition within 8 years of FDA approval under current law, while under the authors' assumption, data exclusivity would protect such drugs for "at least twelve years after launch."  As a result, the authors estimate that between 2020 and 2060 there would be 228 "extra" drug approvals, presumably the result of reinvestment in new drug development of all or a portion of the increased drug revenues (see Goldman et al., 2011, Exhibit 2 below; click on image to expand).

    Exhibit 2 They estimate that the resulting benefits in longevity to be small (essentially zero) for Americans turning 55 in 2020, but to provide an increase in life expectancy of 1.44 years for a 55 year old in 2060 (compared to 1.3 additional years under "the status quo") (see Goldman et al., 2011, Exhibit 3 below; click on image to expand).

    Exhibit 3 While this difference is small (1.7 months), it is on the order of the benefits that would accrue from eliminating obesity among Americans (2.5-13 months).  However, the 55-year-olds in 2020 will "bear the cost of increased drug spending" without reaping any of the benefits; those benefits will accrue to their grandchildren forty years later.  The authors compare the "cost" to the "benefits" per capita of development of new drugs resulting from an increase in the data exclusivity term from 5 to 12 years (see Goldman et al., 2011, Exhibit 4 below; click on image to expand). 

    Exhibit 4 The authors conclude that "[t]his finding is robust with respect to plausible assumptions about the effect of revenues on innovation and other factors," while conceding that "there is uncertainty regarding potential changes in regulations, science, and medicine that were not incorporated into our model."  Some of the authors' assumptions may be unreasonable — for example, the inherent unpredictability of innovator drug research (which is properly used to justify exclusivity in the first place) make their estimate of 228 "extra" new drugs being developed between 2020 and 2060 to be inherently suspect, and just the type of "prediction" that results from economic analysis (which makes fundamental assumptions of the effects of demand on the reality of supply).  However, the benefit of this study is that it provides analytical evidence that, perhaps counter-intuitively, prolonging the term that an innovator can recoup financial regards for innovation can lead to additional innovation.  Perhaps this is not so counter-intuitive when certain facts are taken into consideration.  First, that the cost of drug development has skyrocketed over the 25 years since the Hatch-Waxman Act was passed.  Second, that innovation has become more difficult over that period, as argued by Richard Epstein in his book Overdose: How Excessive Government Regulation Stifles Pharmaceutical Innovation, since the "low-hanging fruit" of antibiotics and other drugs have been developed and drugs for diseases like diabetes are inherently more difficult to find and produce.  Third, that the economics of drug development (affected in part by the Hatch-Waxman regime) discourages development of new drugs and encourages analogues, enantiomers and novel formulations of already-developed drugs.  And other researchers have elucidated the unexpected consequences of the Hatch-Waxman Act, which encourages nothing so much as ANDA litigation (draining resources from further drug development) (see "Maybe Hatch-Waxman Data Exclusivity Isn't So Good For Traditional Drugs After All").

    However, this study has the benefits of being the result of peer-reviewed research, and thus subject to challenge, refutation, or affirmation by other academic researchers.  In an area rife with polemic and interest-group rhetoric, such a study is a welcome oasis of rationality.

    Smith, Lamar In an opinion piece published on POLITICO last week, the new Chairman of the House Judiciary Committee, Rep. Lamar Smith (R-TX) (at right), laid out Congress' resolutions for 2011 ("Judiciary panel's New Year's resolve").  In particular, Chairman Smith noted that Congress (or at least the Republican-controlled House of Representatives) "resolved to cut government spending, promote economic growth and help generate jobs for American workers" in the coming year.  Chairman Smith also promised that "[u]nlike some New Year’s resolutions, this one won't be abandoned in the first weeks of 2011."

    The House Judiciary Committee comprises five subcommittees, one of which concerns intellectual property, competition, and the internet.  Therefore, it was not surprising that a portion of Chairman Smith's article focused on the U.S. patent system.  The Chairman stated that one of the Judiciary Committee's priorities would be "to create jobs for Americans by protecting the innovations that drive economic growth."  Noting that "[n]early 30 percent of U.S. workers are found in intellectual-property-related industries like health care, entertainment, renewable energy and information technology," Chairman Smith writes that "[p]atents protect this intellectual property and encourage the creativity and innovation that generate jobs and increase productivity."  The Chairman argues that "[w]hen inventors and businesses invest in research and development that results in patents, they have the right to benefit from their efforts," adding that "[t]he U.S. economy also benefits by the jobs these patents create."  Outlining the Committee's patent-specific goals for 2011, the Chairman states that "[w]e need to improve our patent system to better protect intellectual property and help ensure that good patents are approved quickly."  Echoing the sentiment of his counterpart in the Senate, Senate Judiciary Chairman Patrick Leahy (D-VT), Chairman Smith notes that "[t]here is bipartisan support for needed revisions to our patent system, which has not been significantly updated in more than a half-century."

    Goodlatte, Bob One day after discussing the Committee's 2011 resolutions, Chairman Smith announced that the Subcommittee on Intellectual Property, Competition, and the Internet would be chaired by Rep. Bob Goodlatte (R-VA) (at left).  The Vice-Chairman of the subcommittee will be Howard Coble (R-NC).  In view of the patent reform bill the House passed in 2007 (see "'Patent "Reform' Bill Passes House of Representatives"), patent practitioners and applicants will watch with interest to see whether the Republican-controlled Judiciary Committee can introduce and pass patent reform legislation, and if so, what this legislation will look like.

    ACLU In a brief filed on November 30, Plaintiffs-Appellees in Association for Molecular Pathology v. U.S. Patent and Trademark Office argue that they have standing; that Myriad's BRCA1/2 isolated DNA claims are invalid under 35 U.S.C. § 101 because they cover laws of nature, natural phenomena, physical phenomena, and products of nature; that Myriad's process claims are invalid under § 101 because they cover laws of nature and abstract ideas; and that Myriad's claims are unconstitutional under the First Amendment.

    PUBPAT Plaintiffs-Appellees begin their brief by arguing that while "Myriad asserts that 'isolated' genes are so different that they constitute a human invention," "Myriad's entire business is premised on the knowledge that the 'isolated' genes are the same as the genes in the body."  The brief also contends that "Myriad has sued or threatened every lab to ever offer clinical BRCA1/2 sequencing and forbids any lab from giving patients a second opinion," and that "[t]his well-known, intimidating campaign of patent assertion has created a substantial chilling effect, and caused leading researchers, clinicians, and patients to abandon BRCA1/2 genetic testing despite having the complete capability and desire to do so."  According to the brief, "[v]irtually the entire medical community has joined Plaintiffs because these patent claims stifle vital clinical and research practices to the detriment of women's health and scientific progress."

    In characterizing Myriad's isolated DNA claims, Plaintiffs-Appellees state that the claims:

    [R]each DNA with introns (non-coding regions) and DNA without introns.  Each claim may also reach cDNA, and "recombinant or cloned DNA isolates as well as chemically synthesized analogs or analogs synthesized using biochemical systems."  All of the claims reach BRCA1/2 genes that are as little as 55% or 60% similar to the genes listed in the patents.  Because polypeptides can be made by DNA with different sequences, those claims defined as DNA that codes for a polypeptide each reach multiple DNA sequences.

    In addition, each of the claims covers small segments of DNA.  Claims 5 and 6 of Patent '282 explicitly claim any DNA having as few as 15 nucleotides that make up BRCA1.  Undisputed evidence in the record establishes that this would reach much of the human genome.

    (Note: Internal citations have been omitted unless otherwise indicated.)  As for Myriad's method claims, the brief contends that they "cover the abstract idea of looking at DNA sequences and thinking about their significance," and "[a]s such, they do not constitute patentable subject matter."

    With respect to the isolated DNA claims, the brief attempts to draw a parallel between the subject matter of Myriad's claims and gold, stating that:

    Under Myriad's view, any naturally-occurring thing that is "isolated" from its natural environment becomes patentable because once separated, it is definitionally different in structure and function.  Thus, "isolated" gold, i.e. gold removed from the streambed, would become patentable because it is structurally different — no longer integrated into the gravel or sand — and functionally different — potentially useful for jewelry-making.  But even if those distinctions are true, the "isolated" gold is still gold and a natural phenomenon.  Myriad also argues that "isolated DNA" cannot perform some of the functions of DNA.  But "isolated" gold can no longer comprise the sediment that influences the stream's channel, flow, and ecology once it leaves the stream.  It is still gold, and if redeposited into the water, it will settle into the streambed and perform its original functions.

    According to Plaintiffs-Appellees, "Myriad appears to argue simply that DNA outside the body is structurally different because it is not surrounded by the body," but "[a]sserting that removing DNA renders it structurally different is the equivalent of asserting that isolating gold or a leaf from a tree makes it different."

    While the brief acknowledges that "DNA is a chemical," it argues that "to suggest that they are chemicals like any other is simply incorrect."  Instead, the brief states that "DNA is foremost an informational molecule," and contends that "[n]o other known molecule has the ability to store vast quantities of information and to transmit that information through self-replication."

    Turning to the first of Plaintiffs-Appellees' four arguments — that they have standing — the brief states that:

    Viewing all the circumstances in this case — including all the facts regarding the ability of Plaintiffs to immediately undertake potentially infringing activity and Myriad's affirmative acts of asserting the patents-in-suit — while keeping in mind the purpose of the DJ Act, leads to the unmistakable conclusion that DJ jurisdiction exists.

    With respect to Plaintiffs-Appellees' ability to immediately undertake potentially infringing activity, the brief notes that "the medical professional Plaintiffs have the immediate ability and desire to provide BRCA screening," that "[t]he genetic counselor Plaintiffs similarly have the immediate ability and desire to begin assisting patients in seeking, receiving, and interpreting BRCA diagnostic testing," that "[t]he patient Plaintiffs . . . have the immediate ability and desire to receive that screening, whether it be to confirm test results received from Myriad, to obtain further analysis of a mutation reported by Myriad to have 'uncertain significance,' or to get a test that they cannot obtain through Myriad," and that "[t]he breast cancer and women's health advocacy organization Plaintiffs have the immediate ability and desire to begin assisting patients in seeking, receiving, and interpreting BRCA diagnostic testing."  As for Myriad's affirmative acts asserting the patents-in-suit, the brief states that "the record establishes that Myriad has sued or threatened every known lab to ever offer clinical BRCA testing, including the University of Pennsylvania lab directed and operated by two of the Plaintiffs, Drs. Kazazian and Ganguly."  The brief also states that "[t]he district court also found that Myriad has systematically and continuously sent threatening patent license letters and demanded license agreements from any academic or other institution wishing to perform BRCA diagnostic testing, including the NYU lab directed by plaintiff Dr. Harry Ostrer."

    Plaintiffs-Appellees next argue that Myriad's BRCA1/2 isolated DNA claims are invalid under 35 U.S.C. § 101 because they cover laws of nature, natural phenomena, physical phenomena, and products of nature.  According to Plaintiffs-Appellees, "[t]he patenting of human genes violates long-established Supreme Court precedent that prohibits the patenting of laws of nature, natural phenomena, products of nature, and abstract ideas."  Citing Diamond v. Diehr, 450 U.S. 175, 185 (1981), and Diamond v. Chakrabarty, 447 U.S. 303, 309 (1980), Plaintiffs-Appellees also suggest that "[c]ontrary to Myriad's assertion, the Court has described 'products of nature' as an exception, along with laws of nature, physical phenomena, natural phenomena, and abstract ideas."

    The brief contends that "[t]hree Supreme Court cases are fundamental to the section 101 analysis":  Chakrabarty, where "[t]he Court considered whether the claimed product had 'a distinctive name, character [and] use' and 'markedly different characteristics from any found in nature'"; Funk Bros. Seed Co. v. Kalo Inoculant Co., 333 U.S. 127 (1948); and American Fruit Growers, Inc. v. Brogdex Co., 283 U.S. 1 (1931).  Plaintiffs-Appellees argue that:

    These seminal cases prohibit the patenting of a product of nature even if it has undergone some degree of change, does not appear naturally in that form in nature, and is novel or highly useful.  They also layout the key clues to applying section 101: whether the product has a distinctive name, character and use, Chakrabarty, 447 U.S. at 309-10; whether it has markedly different characteristics from any found in nature, id. at 310; and whether the patent is on "nature's handiwork" or covers qualities that are the work of nature. Id.; Funk Bros., 333 U.S. at 130.

    Plaintiffs-Appellees distinguish "chemical molecules like water [that] can be described as H2O, HOH, or OH2 because they consist of any two hydrogen atoms and an oxygen atom," from DNA, which the brief states "is not described according to the sugars and phosphates of its backbone, but by its nucleotide sequence." "Because this blueprint is the defining characteristic of DNA and remains the same before and after isolation," Plaintiffs-Appellees contend that "isolated DNA has neither a distinctive name, character, and use from naturally-occurring DNA nor markedly different characteristics."

    The brief also suggests that in view of the DOJ's amicus brief (see "DOJ Tries to Be All Things to All Constituencies in Myriad Amicus Brief"), the Federal Circuit need not defer to guidance from the USPTO (in the form of the Office's utility examination guidelines).  According to Plaintiffs-Appellees:

    [T]he Utility Guidelines no longer represent the position of the United States.  After consultation with numerous federal agencies, including the PTO, U.S. Br. 1, the U.S. concluded that "isolated but otherwise unaltered genomic DNA is not patent-eligible subject matter under 35 U.S.C. § 101."  U.S. Br. 18.  If deference to the decisions of the United States is due, that deference now supports invalidation of the claims.

    The brief also argues that other precedent supports the conclusion that isolated DNA is not patentable.  Among the cases cited by Plaintiffs-Appellees are:  Ex parte Latimer, 1889 Dec. Comm'r Pat. 123 (1889) (purified pine needle fiber); Gen. Elec. Co. v. De Forest Radio Co., 28 F.2d 641 (3d Cir. 1928) (substantially pure tungsten); In re King, 107 F.2d 618 (C.C.P.A. 1939) (vitamin C purified from lemon juice); In re Merz, 97 F.2d 599 (C.C.P.A. 1938) (purified ultramarine); In re Marden (Marden II), 47 F.2d 958 (C.C.P.A. 1931) (purified vanadium); In re Marden (Marden I),47 F.2d 957 (C.C.P.A. 1931) (purified uranium).  As for lower court cases that Myriad relies on to support its position for patentability, the brief contends that those cases "did not squarely address subject matter eligibility under section 101 or are otherwise inapposite."  In a footnote, Plaintiffs-Appellees also argue that "Myriad's reliance on section 103(b)(1) to support the patentability of isolated DNA is similarly misplaced."  In particular, Plaintiffs-Appellees contend that "[t]he fact that Congress mentioned 'nucleotide sequence' in section 103(b)(1) — a statutory provision which deals with the obviousness of processes — does not support the notion that Congress intended isolated DNA to be patentable compositions.  An organism can be engineered to express a 'nucleotide sequence' that is not naturally-occurring."

    Returning to the DOJ brief, Plaintiffs-Appellees note that "[a]micus United States argues that claims limited to cDNAs would not violate section 101."  While stating that this issue is not material to the case, the brief argues that "should this Court choose to reach the cDNA question, it should also invalidate claims on cDNA that is an exact copy of naturally-occurring mRNA."  In addition, the brief contends that "cDNA does exist naturally in the body through a naturally-occurring process in which RNA is reverse-transcribed into cDNA," and that "[s]ome of these cDNAs are then reinserted into the genome in the form of pseudo genes."

    Plaintiffs-Appellees devote only a few pages of the brief to their final two arguments.  With regard to their argument that Myriad's process claims are invalid under § 101 because they cover laws of nature and abstract ideas, the brief states that "[c]onsidered as a whole, the method claims at issue here clearly cover a phenomenon of nature — whether two BRCA sequences are different or the same."  In particular, the brief contends that:

    Claim 2 of '857 covers comparing a BRCA2 sequence from a sample with the wildtype sequence, wherein any alteration indicates a predisposition to breast cancer, and further illustrates the preemptive effect.  The claim does not specify which alterations are covered and makes the scientifically incorrect assumption that any alteration indicates cancer predisposition.  Thus, the claim exemplifies how a patent on a general correlation between a gene and disease monopolizes a law of nature.  A scientist who wants to identify which alterations in fact indicate a breast cancer predisposition will run afoul of the patent claim as soon as he or she compares two gene sequences and considers the significance of an alteration.

    As for Myriad's argument that its process claims satisfy the transformation prong of the machine-or-transformation test, Plaintiffs-Appellees counter that in order to satisfy the test:

    Myriad imports entirely new terms and processes into the claims' plain language.  Myriad argues that "sequence" should be understood as the isolated DNA molecule and that the method claims necessarily involve isolating, sequencing, and hybridization of DNA or genes using a primer or probe.  Yet, none of these processes is required by the challenged claims themselves and for that reason, they cannot be magically inserted.

    The brief also points to dependent claims not involved in the suit, which do require hybridizing, amplifying, electrophoresing, and/or cloning.

    Finally, with respect to Plaintiffs-Appellees' First Amendment argument, the brief states that:

    None of the method claims purports to cover any specified process of comparing or analyzing gene sequences or testing therapeutics.  The only instructive part of these claims is that at the end, the medical professional thinks, "They are the same" or "They are different" or "They are different in a way that is significant."  In other words, it is the thought that is patented, not a particular process.  Enforcement of such a patent by a governmental actor, such as the Defendant University of Utah Research Foundation, would violate the First Amendment.

    Senate Seal Members of Congress having sent their letter to the Food and Drug Administration on December 21st (see "Representatives Send Letter to FDA to Explain Data Exclusivity Provisions of Biosimilars Legislation"), on January 7th, it was the Senate's turn.  In their letter, Senators Kay Hagan (D-NC), Orrin Hatch (R-UT), Michael Enzi (R-WY), and John Kerry (D-MA) address the same provisions of the Act and give the Agency substantially the same message as to their "intent" in passing the legislation that their House colleagues did two weeks earlier.

    Agency action that prompted the Senators' letter was the portion of the Public Notice in the Federal Register requesting public input (significantly from the innovator and biosimilar communities) regarding the meaning of the term "exclusivity" in the statute (Patient Protection and Affordable Care Act (P.L. 111-148)):

    What factors should the agency consider in determining whether a modification to the structure of the licensed reference biological product results in a change in safety, purity, or potency, such that a subsequent Biologic License Application (BLA) may be eligible for a second 12-year period of marketing exclusivity?

    FDA Like their colleagues in the House of Representatives, the Senators assert that "[t]he Act does not provide market exclusivity for innovator products."  Rather, the exclusivity referenced in the Act is data exclusivity, "which prohibits FDA from allowing another manufacturer of a highly similar biologic to rely on the Agency's prior finding of safety, purity and potency for the innovator product," qualified by the phrase "for a limited period of time."  The Senators, like the MOCs, make the distinction that the biosimilar manufacturer is not prohibited from "developing its own data to justify FDA approval of [its own BLA] rather than an abbreviated application that relies on the prior approval [and data] of a reference product."

    The letter also reminds the Agency that the Act does prohibit it from granting more than one period of data exclusivity to the innovator (but not, of course, to the putative follow-on biologic manufacturer who undertakes filing its own BLA, which upon award would benefit from its own 12-year data exclusivity period).  This is clear from the qualifiers "from the same company" included in the letter's synopsis of these provisions of the Act:

    The Act explicitly precludes any period of data exclusivity for the following:

    o   A supplement to a BLA; or
    o   A subsequent BLA (from the same company) for a non-structural change that results in a new indication, route of administration, dosing schedule, dosage form, delivery system, delivery device, or strength; or
    o   A subsequent BLA (from the same company) for a structural change that does not result in a change in safety, purity or potency.

    Like the letter from the House members, the Senators' letter closes with a statement that "the Act provides incentives for innovators to research and develop new treatments for patients," including an innovator company that "modifies an approved product to produce a change in safety, purity or potency [presumably, for the better]."  Approval of such a "new [drug] product" will not change the data exclusivity for the "first-generation" product (which will expire "as usual"), but will be entitled to its own 12-year data exclusivity period like all new biologic drug products.

    While it might be easy to dismiss this letter (like the MOC's earlier letter) as unadorned politics (particularly since both letters are not binding on the agency or a reviewing court in implementing or interpreting the statute), it does reflect bipartisan consensus on these issues.  The letters proffer a definition of "exclusivity" that attempts to prevent "evergreening" while fostering innovation, and to encourage an alternative path for biosimilar approval for those biologic drugs having sufficient market profit potential to justify the effort and expense of avoiding the innovator's data exclusivity by producing its own.  The combination of interpretations may also encourage development of "bio-betters," but that may also require the FDA to make decisions on questions such as the meaning of the terms "highly similar" and "interchangeable" that (unlike the meaning of "exclusivity") Congress has left to the agency's discretion and the exercise of its expertise.
