    Law Institute (PLI) will be holding its Fundamentals of Patent Prosecution
    2013: A Boot Camp for Claim Drafting & Amendment Writing seminar on May
    14-16, 2013 in Chicago, IL, on June 12-14, 2013 in New York, NY, and on July
    10-12, 2013 in San Francisco, CA.  The
    three-day program, which is directed to patent prosecuting and litigating
    attorneys and patent agents with or without a Patent Office registration number
    or little patent experience, will focus on teaching the basics of claim
    drafting, patent application preparation and prosecution, as well as a review
    of recent developments in the law.  A
    litigator's perspective is also presented to show how drafting and prosecution
    can influence the development, and often the outcome, of subsequent patent
    litigation.  The seminar will feature
    lectures in the morning followed by small clinic sessions in the afternoon,
    with day 1 focusing on invention disclosures and patent preparation, day 2 on
    prosecution and issuance, and day 3 on litigation and opinion drafting.  Lectures will explain:


    How to decide what elements of the invention should be included in the patent;

    How to prosecute an application to result in allowance of an enforceable
    patent;•
    How to interview an Examiner;

    How to use reissues, reexaminations, and other post-issuance proceedings;

    How to anticipate patent litigation issues during the patent prosecution
    process; and

    How to approach patent opinion drafting.

    entitled "Kirtsaeng: Implications for Patent Law" on
    April 11, 2013 beginning at 2:00 pm (ET). 
    A panel consisting of Buckmaster
    De Wolf of General Electric
    Co.; Annette Hurst of Orrick,
    Herrington & Sutcliffe LLP; and Gary
    Hoffman of Dickstein Shapiro LLP will consider how factors
    governing international patent exhaustion are different from those governing
    copyright law and whether they will convince the U.S. Court of Appeals for the
    Federal Circuit to affirm Jazz Photo when it next has the opportunity.
    The panel also will discuss steps patent owners can take now to deal with a
    possible shift to international patent exhaustion, including:


    licensing provisions and other contractual restrictions,

    localizing product offerings, and

    "tethering" patented products so they require an interaction with a
    central server using "unlock codes" that restrict international transfer.

    USPTO SealThe U.S. Patent and Trademark Office ("USPTO") published
    its final rule in the April 3, 2013 Federal
    Register
    (78 Fed. Reg. 20180) in preparation for adopting new USPTO Rules of Professional
    Conduct ("USPTO Rules").  As we reported previously when the proposed
    rules were announced (see "USPTO Proposes Update to Code of Professional Responsibility"), the new USPTO Rules seek to conform the ethical obligations
    for representing others before the USPTO to the ABA Model Rules of Professional
    Conduct, which have been adopted in some form
    by every state (except California) and the District of Columbia. 

    The adoption of the new USPTO Rules is
    significant for any patent practitioner that has a USPTO registration number.  On the one hand, the updated USPTO Rules are welcome news for attorney practitioners, because currently
    such individuals are required to know and abide by the ethics rules of the
    state or jurisdiction in which they practice.  Because the USPTO had been
    operating under the Patent and Trademark Office Code of Professional Conduct,
    which was based on the former ABA Model Code from 1980, patent attorneys were
    required to maintain adherence to two different sets of ethical obligations.  On
    the other hand, non-lawyer patent practitioners (patent agents) will now be
    subject to the new USPTO Rules, even though they may not be aware of the
    differences and subtleties of the ABA Model Rules.  It will be important for
    these individuals to become accustomed to the new USPTO Rules, especially
    where they differ from the previous Patent Office Code.  In fact, Dennis Crouch, Associate Professor
    of Law at the University of Missouri School of Law and author at the Patently-O blog, submitted a comment expressing
    the concern that the Patent Office not unduly focus on the experience of
    attorneys at the expense of these non-lawyer patent practitioners.  The USPTO Rules will go into effect on May 3,
    2013.

    Confidentiality of Information

    After the proposed rules were promulgated on October 18, 2012,
    nineteen individuals or organizations submitted comments to USPTO.  This author submitted a comment on behalf of
    Patent Docs regarding concerns about the new disclosure-of-confidential-information
    rules, as outlined in a previous post (see "USPTO Proposes Update to Code of Professional Responsibility").  These concerns were echoed by the four organizations that filed
    comments:  the Intellectual Property Owners Association (IPO), the American Bar
    Association (ABA), the American Intellectual Property Law Association (AIPLA),
    and the Minnesota Intellectual Property Association.  Even though each of these comments addressed
    the problem slightly differently, the underlying concerns were still the same.

    In a nutshell, new rule § 11.106, which is based on ABA Model Rule
    1.6, states that a practitioner shall not reveal a client's confidential
    information without informed consent, implied authorization, or permission
    under the rules.  Both the new USPTO Rules and the ABA Model Rules include
    circumstances in which a practitioner "may" reveal such confidence,
    such as disclosing information that may prevent death, bodily harm, or fraud.  However,
    even in the cases where death, bodily harm, or fraud may result, the
    practitioner is still not required to reveal such information, but rather has
    permission to do so.  The new USPTO Rules diverge from the ABA Model Rules in
    one important respect:  the new USPTO Rules at § 11.106(c) include a type of
    information that is mandatory to reveal:  "A practitioner shall disclose to
    the Office information necessary to comply with applicable duty of disclosure
    provisions."  In other words, under this proposed rule, a finding that
    relevant information was intentionally withheld by a practitioner involved in
    the prosecution of an application will not only subject a patent to becoming
    unenforceable, it will result in an ethical violation by the practitioner.

    Of course, this requirement has the possibility of trapping a
    patent practitioner between two ethical obligations — a proverbial rock and a
    hard place.  Importantly, this obligation
    to disclose is not limited to the confidential information from the particular
    prosecution client, but instead extends to any confidential information
    belonging to any other client, provided it is material to the first client's
    application.  To be fair, a similar quandary may have already existed, because
    if a patent attorney is aware of such third-party confidential information,
    there was already a requirement to disclose it in order to prevent the patent
    from becoming unenforceable.  Nevertheless, most clients would prefer that
    confidential information not be made publically accessible in another client's
    patent file because the practitioner was required to satisfy his or her ethical
    obligation to the other client.

    The biggest concern expressed in the comments about this issue was
    whether an attorney in such an ethical quandary would be able to withdraw from
    the case, and thereby discharge the ethical obligation.  In the published final rule, the USPTO addressed these comments, but did not change the proposed
    rule.  The USPTO's response provided some justification for the rule as drafted.  For example, the USPTO appears to suggest that such an ethical quandary is
    unlikely because the restrictions on conflicts of interest "would
    generally prevent a practitioner from accepting clients who may have
    potentially adverse interests."  Of course, this is not the test for
    whether there is a conflict of interest under ABA Model Rule 1.7 or USPTO Rule
    107.  Instead, a concurrent conflict of interest exists where the representation
    of two clients would be directly adverse, or where there would be a significant
    risk that the representation of either client would materially limit the
    representation of the other.  Indeed, a requirement to disclose confidential
    information can arise when a current client discloses information to a
    practitioner that happens to be material to the patentability of another client's
    application.  Conflict screening will generally not prevent these ethical
    quandaries.

    This does, however, bring up another interesting issue regarding
    the interplay between the duty to disclose and the rules on whether a conflict
    exists.  The USPTO Rules include a
    version of ABA Model Rule 1.10, in which the existence of a conflict of
    interest is imputed to everyone at a firm.  In other words, if another attorney at a firm is performing legal
    services for a client, then every attorney at that firm is thought to be
    working for that client, even if the other attorneys at the firm have no
    knowledge of that client.  Moreover,
    unless the conflict arises from an association with another firm, it is
    generally not possible to "screen" or "wall" those
    attorneys off to avoid the conflict.  Instead, in such instances where a conflict would arise, the firm is
    forced to decline the work that would cause the conflict.  This is not true of the duty of
    disclosure.  Whether a practitioner is
    aware of a reference that is material to the patentability of an application is
    personal to that patent attorney or agent.  Knowledge of a material reference is not imputed, so different attorneys
    representing different clients in similar spaces could be aware of art that
    would be material to the other client's application and not be required to
    disclose it.  This is because that
    attorney needs to have actual knowledge of the reference.

    Nevertheless, whether those attorneys had actual knowledge of such
    a reference is a factual matter, and the consequences of a court finding such knowledge
    can be catastrophic for a client.  Therefore, firms can take precautions to avoid even the appearance of
    impropriety.  For example, firms can
    obtain separate USPTO customer numbers for use with specific clients.  That way, if one client's reference becomes relevant
    to another client's application, as long as the attorneys of the second client
    are not associated with the first client's customer number, a presumption could
    be drawn that they never had knowledge of the reference in the first
    place.  The only problem with this
    approach, however, is that clients often hire a firm because of the firm's
    experience prosecuting particular types of applications.  Unfortunately, it is this experience that can
    potentially give rise to these conflicts, or requirements to disclose
    information.

    Ultimately, the USPTO did respond to the expressed concern by noting
    that a practitioner in such a situation could be able to withdraw from
    representation.  In the response to this comment, the USPTO pointed to § 1.116
    of the new Rules, which provides that in certain situations, a practitioner may
    seek to withdraw to avoid a conflict of interest.  Moreover, in the "Discussion
    of Specific Rule," the USPTO specifically stated that "if a
    practitioner has a conflict of interest in a given matter, arising from a
    different client, timely withdrawal by the practitioner from the given matter
    would generally result in OED not seeking discipline for conflicts of interest
    under part 11."  Even though the use
    of the word "generally" is troubling in this explanation, this is
    probably the best practical solution short of amending the rules.

    USPTO SealIn the past week, the U.S.
    Patent and Trademark Office has published two Federal Register notices to
    implement technical corrections to the Leahy-Smith America Invents Act.  On Monday, the Office issued an interim final
    rule (78 Fed. Reg. 19416)
    that revises the rules of practice to implement changes to the patent term
    adjustment (PTA) provisions as provided in § 1(h) of the Technical Corrections Act,
    which was enacted on January 14, 2013.  Section
    1(h) of the Technical Corrections Act specifies that the fourteen-month period within
    which the Office must issue a notice of rejection under 35 U.S.C. § 132 or
    notice of allowance under 35 U.S.C. § 151 (see
    35 U.S.C. § 154(b)(1)(A)(i)(II)) and the three-year application pendency period
    provided by 35 U.S.C. § 154(b)(1)(B) are to be measured from the same date, i.e., the date of commencement of national
    stage under 35 U.S.C. § 371.

    Section 1(h) also revises
    the provisions for notifying applicants of PTA determinations and for
    requesting reconsideration and judicial review of the Office's PTA determinations.  With regard to notifying applicants of PTA determinations,
    the interim rule changes the rules of practice to eliminate the need for the
    Office to provide an initial PTA determination with the notice of allowance, before
    the PTA under 35 U.S.C. §§ 154(b)(1)(A)(iv) (for not issuing a patent within
    four months following payment of the issue fee) and 154(b)(1)(B) (for not
    issuing a patent within three years after the actual filing date) can be
    determined.  Although the Office will no
    longer provide an initial PTA determination with the notice of allowance, under
    37 C.F.R. § 1.705(c) Applicants must still file a request for reconsideration
    prior to the issuance of a patent in order to reinstate PTA reduced pursuant to
    37 C.F.R. § 1.704(b) for failing to reply to a rejection, objection, argument,
    or other request within three months of the date of mailing of the Office
    communication.  With regard to requesting
    reconsideration of the Office's PTA determinations, the rules of practice are also
    being changed to allow applicants to extend the two-month period for filing a
    request for reconsideration of the PTA indicated on a patent by an additional
    five months after the date that the patent was granted under the provisions of 37
    C.F.R. § 1.136(a).

    The changes to 37 C.F.R. §§
    1.702, 1.703, and 1.705 provided by the interim rule apply to any patent
    granted on or after January 14, 2013, and the change to 37 C.F.R. § 1.704
    applies to any application for which a notice of allowance was mailed on or after
    April 1, 2013.  The Office will be
    accepting comments regarding the interim rule until May 31, 2013.  Comments can be sent by e-mail to AC84.comments@uspto.gov; by regular mail addressed to:  Mail Stop
    Comments—Patents, Commissioner for Patents, P.O. Box 1450, Alexandria, VA,
    22313–1450, marked to the attention of Kery A. Fries, Senior Legal Advisor,
    Office of Patent Legal Administration, Office of the Deputy Commissioner for
    Patent Examination Policy; or via the Federal eRulemaking Portal.

    Last week, the Office also
    issued a final rule (78 Fed. Reg. 17871)
    to implement technical corrections to the AIA with respect to inter partes review proceedings.  In particular, the final rule eliminates the
    nine-month "dead zone" for filing an inter partes review petition challenging a first-to-invent patent
    or reissue patent by permitting a petitioner to file an inter partes review petition challenging a first-to-invent patent
    or reissue patent upon issuance.  Revised
    37 C.F.R § 42.102 provides, in part, that:

    A petition for inter partes review of a patent must be filed after the later of
    the following dates, where applicable:
        (1) If the patent is a
    patent described in section 3(n)(1) of the Leahy-Smith America Invents Act, the
    date that is nine months after the date of the grant of the patent;
        (2) If the patent is a
    patent that is not described in section 3(n)(1) of the Leahy-Smith American
    Invents Act, the date of the grant of the patent[.]

    The effective date
    provision of AIA § 3(n)(1) states that:

    Except as otherwise provided in this section,
    the amendments made by this section shall take effect upon the expiration of
    the 18-month period beginning on the date of the enactment of this Act [i.e.,
    March 16, 2013], and shall apply to any application for patent, and to any
    patent issuing thereon, that contains or contained at any time–
        (A) a claim to a claimed invention that has an
    effective filing date as defined in section 100(i) of title 35, United States
    Code, that is on or after the effective date described in this paragraph; or
        (B) a specific reference under section 120, 121, or
    365(c) of title 35, United States Code, to any patent or application that
    contains or contained at any time such a claim.

    Thus, 37 C.F.R § 42.102(1)
    encompasses first-inventor-to-file (FITF) patents and 37 C.F.R § 42.102(2)
    encompasses first-to-invent patents.

    The final rule implementing
    technical corrections with respect to inter
    partes
    review proceedings took effect on March 25, 2013.

    3In an article published in
    the current issue of Genome Medicine,
    Jeffrey Rosenfeld of the University of Medicine & Dentistry of New Jersey
    and Christopher Mason of Cornell University contend that due to the
    non-specificity of sequence uniqueness across the genome and the broad scope of
    claims to nucleotide sequences, the Supreme Court and Congress should limit the
    patenting of existing nucleotide sequences ("Pervasive sequence patents cover the entire human genome," Genome Medicine 5:27 (2013)).  According to the two researchers, the Association for Molecular Pathology v.
    Myriad Genetics, Inc.
    case affords the Supreme Court with an opportunity to
    resolve the "sharp conflict between the public goods of medical knowledge and
    improved health and the private goods of rewarding innovation and entrepreneurial
    risk-taking" that is presented by gene patents.

    The
    authors begin by stating that "the broadest intellectual property rights
    on BRCA sequences" come from four claims in Myriad's U.S. Patent No.
    5,747,282:

    1.  An
    isolated DNA coding for a BRCA1 polypeptide, said polypeptide having the amino
    acid sequence set forth in SEQ ID NO:2.

    2.  The isolated DNA of claim 1, wherein said DNA
    has the nucleotide sequence set forth in SEQ ID NO:1.

    5.  An isolated DNA having at least 15
    nucleotides of the DNA of claim 1.

    6.  An isolated DNA having at least 15
    nucleotides of the DNA of claim 2.

    The
    article takes the Federal Circuit to task for (twice) "declar[ing] that even
    a short, isolated DNA molecule such as 'ACGT' is different from the
    'NNNNN-ACGT-NNNNN' present within a chromosome (AMP v. Myriad, Federal Circuit 2012), because it will not be
    connected to sugar via a phosphodiester bond and will have a hydroxyl group instead
    of a bond to a phosphate."  According
    to the authors, the Federal Circuit's ruling means that "even a 15
    nucleotide fragment of DNA in Claim #6 from Patent '282 is claimed to be
    'markedly different'."

    The
    authors, however, find the Federal Circuit's ruling to be overly broad for
    three reasons:

    First, it relies on the sequences having chemical
    features and side-chains that are not actually present in the patents . . . :
    the claims are for a linear series of nucleotides, not a specific chemical
    structure.  Second, if allowed to be so
    broad, these claims could also create a monopoly on all epigenetic and chemical
    variations of these sequences. Third, and perhaps most importantly, the
    non-specificity of 15mer sequences creates unclear infringement liability that
    has been even noted by the Court.

    To
    investigate this last point, the authors examined the incidence with which
    15mers from a given gene matched 15mers in other genes using the Consensus
    Coding Sequences (CCDS) database of 18,382 high-confidence genes.  This analysis showed that "every gene in
    the CCDS database had a 15mer that matched the sequence of at least one other
    gene," with the "[t]he number of matching genes ranged from as few as
    5 (for MTRNR2L7) or 689 (for BRCA1) to as high as 7,688 (for TTN),
    corresponding to 0.01%, 4%, and 42% of all genes in the human genome."  The authors note that 99.999% of 15mers in
    the human genome are repeated at least twice.

    According
    to the authors, this analysis "demonstrate[s] that short patent sequences
    are extremely non-specific and that a 15mer patent claim from one gene will
    always 'cross-match' and patent a portion of another gene as well."  In support of this point, the authors
    identified 58 patents whose claims covered at least 10% of the bases of all human
    genes, with the claimed sequences of U.S. Patent No. 7,795,422
    matching 91.5% of human genes, and the claimed bovine sequences of U.S. Patent
    No. 7,468,248
    matching 84% of human genes.  Arguing
    that "[t]he demonstrated non-specificity of sequence uniqueness across the
    genome suggests that the Supreme Court should use [the Myriad] case to clarify the law on gene patents," the authors
    contend that "[i]f patent claims that use these 15mer or other short k-mer
    sizes are enforced, it could potentially create a situation where a piece of
    every gene in the human genome is patented by a phalanx of competing patents,
    with potentially harmful consequences for genetic testing laboratories and
    research groups performing targeted sequencing on any gene, in virtually all
    species."

    The
    authors' conclusion regarding the broad scope of Myriad's 15mer claims,
    however, is not particularly ground-breaking given that Kepler et al. similarly concluded in a 2010 Genomics paper that claim 5 of the '282
    patent was "exceptionally broad" (see
    "Caught in a Time Warp: The (In)validity of BRCA1 Oligonucleotide Claims").  Kepler et
    al
    . suggested that "if human genes were random strings of nucleotides,
    one would expect a human gene to contain an average of 15 15-mers claimed under
    the ['282] patent," and in fact found that 80% of 713 human mRNAs
    deposited in 1994 (the earliest effective filing date of the '282 patent is August 12, 1994) contained at least one of the claimed 15mers.  Thus, Kepler et al. indicates that claims 5 and 6 are sufficiently overbroad as
    to be easily invalidated.  Because the analysis of Kepler et al. and Rosenfeld and Mason suggest that claims 5 and 6 of the '282 patent (and perhaps 15mer claims
    in other patents) would likely not withstand an invalidity challenge, it is
    unlikely that these claims will have the adverse impact on the "medical
    good" suggested by the authors of the Genome
    Medicine
    article.

    One
    interesting result presented in the Genome
    Medicine
    article is that even longer nucleotide fragments from known genes
    matched the sequence of sequences in other genes.  In particular, the paper points out that
    "even 1,000 nucleotide fragments from known genes could still match 117
    other genes."  However, the paper does not
    present any additional information regarding the 1,000 nucleotide fragment (or
    fragments) that yielded such matches.

    Finally,
    it should be noted that Dr. Mason submitted two declarations when the Myriad case was before the District
    Court.  In a Supplemental Declaration
    submitted in response to Myriad's brief and Statement of Material Facts, Dr.
    Mason stated that claim 6 of the '282 patent was "so broad that it
    includes at least 4% and as much as 100% of the genes in the human genome."

    Supreme Court Building #1The
    Supreme Court heard oral argument in Federal Trade Commission v. Actavis (the caption for what was Federal
    Trade Commission v. Watson Pharmaceuticals, Inc.
    in the 11th Circuit opinion below) last Monday, with Deputy Solicitor General Malcolm
    Stewart arguing for the government and Jeffrey
    Weinberger arguing for Respondents.  Justice
    Alito recused himself from any involvement with this case, raising the
    possibility that the Court could not render a decision that would resolve the
    circuit split between the 11th Circuit decision at issue here and
    the K-Dur case in the Third Circuit (In
    re K-Dur Antitrust Litigation
    ).

    To
    briefly recap, the case involved a reverse payment
    settlement between NDA holder Solvay Pharmaceuticals and ANDA filers Watson
    Pharmaceuticals and Paddock Pharmaceuticals over AndroGel, a prescription
    testosterone formulation prescribed for treating hypogonadism.  Unimed (acquired
    by Solvay and later acquired by Abbott) and Besins Healthcare S.A. held the
    NDA, as well as Orange Book-listed U.S. Patent No. 6,503,894
    directed to the formulation; this patent will expire in August 2020. 
    Watson and Paddock filed separate ANDAs having Paragraph IV certifications that
    the '894 patent was invalid or unenforceable, and Unimed/Besins timely filed
    suit pursuant to 35 U.S.C. § 271(e)(2) in the U.S. District Court for
    the Northern District of Georgia.  The lawsuit was pending longer than the
    statutory 30-month stay, and the FDA approved Watson's ANDA, but neither Watson
    nor Paddock launched "at risk" (i.e., before the lawsuit had
    been decided).  As part of the suit, both Watson and Paddock did not
    contest that their products would infringe the '894 patent, but rather that the
    patent was invalid or unenforceable.  However, before the District Court could rule
    on defendants' summary judgment motions after a Markman hearing, the
    parties settled; the Court entered a Stipulation of Dismissal
    against Watson and a permanent injunction against Paddock.

    The case on appeal arose pursuant to an
    investigation by the FTC of these settlement agreements under 21 U.S.C. § 355 (2003).  The FTC alleged violations of Section 5a of the Federal
    Trade Commission Act under 15 U.S.C. § 45(a)(1).  The suit was transferred
    from the Central District of California to the Northern District of Georgia,
    where the District Court granted defendants' motion to dismiss pursuant to Fed.
    R. Civ. Pro. 12(b)(6) (failure to state a claim).  In doing so, the
    District Court rejected the FTC's contentions in its complaint "(1) that
    the settlement agreement between Solvay and Watson is an unfair method of
    competition; (2) that the settlement agreement among Solvay, Paddock, and Par
    is an unfair method of competition; and (3) that Solvay engaged in unfair methods
    of competition by eliminating the threat of generic competition to AndroGel and
    thereby monopolizing the market."  The basis for the District Court's
    action was that, in the 11th Circuit, reverse payments did not constitute
    anticompetitive behavior "so long as the terms of the settlement remain
    within the scope of the exclusionary potential of the patent, i.e., do
    not provide for exclusion going beyond the patent's term or operate to exclude
    clearly non-infringing products, regardless of whether consideration flowed to
    the alleged infringer."

    The 11th Circuit affirmed, and
    the FTC convinced the Court to review this decision rather than the Third
    Circuit's K-Dur decision (see "FTC Asks Supreme Court to Play Favorites in Reverse Payment Settlement Agreement Cases").

    Supreme Court Courtroom_cAt
    oral argument, the government began with its strongest statement of its argument:  "a
    payment from one business to another in exchange for the recipient's agreement
    not to compete is an paradigmatic antitrust trust violation."  The question before the Court, according to
    the government, is whether the same payments arising in settlement of patent
    infringement (ANDA) lawsuits should be permitted, thus pandering to the Court's
    displeasure with patents, patent law, and "special rules" for patents.

    The government's grounds for its position is that such settlements "subvert
    the competitive process by giving generic manufacturers an incentive to accept
    a share of their rival's monopoly profits as a substitute for actual
    competition in the [marketplace]."  This assertion was met by a
    question from Justice Scalia, who asked "how is a payment different from a
    geographic division of a market via an exclusive license?"  The government's first response, that
    exclusive licenses are contemplated by the Patent Act, was not convincing
    (Justice Scalia said it "doesn't impress"), so the government
    enunciated a second rationale (which would resonate with the Justices later in
    the argument), that a license "doesn't give the . . . infringement defendant
    anything that it couldn't hope to achieve by prevailing in the lawsuit."  Justice Scalia said that this is just another
    way to say that the defendant would get to make money, and asked why the
    patentee could not "short circuit" the process and just give the
    defendant the money to make them "go away."  The government responded that the difference
    is that the payment is  "a
    substitute for earning profits in a competitive marketplace," reflecting
    the FTC's preference for "competition."

    The
    government seemed to assert a refinement of its position (which, it should be
    recalled, began with the proposition that reverse payment settlement agreements
    in ANDA litigation should be a per se
    violation of the Sherman Act), now arguing that the "logical subject of
    compromise" should be that the generic drug maker would be able to enter
    the marketplace at some time before it would have if the branded patentee had
    won the underlying ANDA lawsuit and after the time it could have entered the
    marketplace if the generic drug maker won.  "That's an actual subject of compromise and we don't have a problem
    with that," according to Mr. Stewart.

    Justice
    Scalia asked for a case where the patentee has been held liable under the
    antitrust laws for doing something within the scope of the patent, and the government
    said yes, provided that you define "scope of the patent" the way it
    characterized the Respondents' position, that "the goods that are being
    restricted are arguably encompassed by the patent and the restriction doesn't
    extend past the date when the patent expires."  The government also analogized reverse
    payment settlement agreements to resale price maintenance agreements (which the
    Court held to be illegal in the face of patent protection) because "there's
    nothing in the Patent Act that says you can pay your competitor not to engage
    in conduct that you believe to be infringing."  And the government reminded the Court that
    reverse payment settlement agreements involve (typically) a non-sham allegation of infringement rather than a
    finding of infringement.

    Justice
    Ginsberg mentioned that this seems to be a change in the government's position,
    and Mr. Steward argued that while the FTC hasn't changed its position, the DOJ had
    previously "advocated . . . a test that would focus on the strength and scope
    of the patent[, t]hat is, the likelihood that the brand name would . . . ultimately have prevailed if the suit had been litigated to judgment."  The government's current position is that
    these agreements are "presumptively unlawful with the presumption able to
    be rebutted in various ways."

    Justice
    Kennedy asked whether one of these ways was assessing the "strength"
    of the infringement case, something he identified as his "problem,"
    because the government's test is "the same for a very weak patent as a
    very strong patent," which "doesn't make a lot of sense."  In response, the government shifted the focus
    of its argument to be whether there has been a payment "that would tend to
    skew the parties' choice of an entry date, that would tend to provide an
    incentive . . . for the generic to agree to an entry date later than the
    one that it would otherwise insist on."  Justice Kennedy suggested that the
    determination — of how much and in what direction the market entry was "skewed" — would "itself reflect the
    strength or weakness of the patent so that the market forces take that into
    account."  The government's response
    was that "legitimate" agreements would be those where an assessment
    of the strength of the patent would determine when the generic drug maker entered the marketplace — presumably
    such agreements would not involve
    payments.  But "the problem with the
    reverse payment is that it gives the generic an incentive to accept something
    other than competition as a means of earning money," Mr. Stewart advocated
    as a (the?) principle issue the government had with these settlements.

    Justice
    Scalia posited that this issue reflected a problem with the Hatch-Waxman Act
    (as shown by attempts to "fix" these problems, notably by the
    Medicare Prescription Drug, Improvement and Modernization Act of 2003), and the government responded that "these types of payments appear to be
    essentially unknown in other lawsuits and other patent infringement cases"
    (but Justice Scalia reminded Mr. Stewart that "suits against this kind of payment" also don't exist outside the Hatch-Waxman
    context, either).  The Justice suggested that
    Hatch-Waxman "made a mistake by not foreseeing these types of arrangements,"
    further saying:

    And in order to rectify the mistake, the FTC comes in and brings in
    a new interpretation of antitrust law that did not exist before, just to
    make up for the mistake that Hatch-Waxman made, even though Congress has tried
    to cover its tracks in later amendments, right, which . . . deter . . . these payments.

    Not
    surprisingly, the government was not willing to go that far, but Justice Scalia
    asked why the Court should be willing to "overturn understood antitrust
    law" to fix Congress's mistake in Hatch-Waxman?

    Turning
    the argument back to antitrust law, the government argued for a hypothetical
    where Watson developed a new drug that would compete with AndroGel and Solvay
    paid them not to market it; this would be a clear antitrust violation, according
    to the government, "even though Watson's ultimate ability to market the
    new drug would depend on FDA approval that might or might not be granted."  The government's point was that the
    underlying illegality should not be vitiated by intervening considerations (FDA
    approval, or in this case patent protection, albeit requiring the Court to
    ignore the statutory presumption of validity).  Mr. Stewart cited Professor Hovenkamp for the proposition that "in
    the typical market if a patent holder were known to have paid a large sum of
    money to a competitor who had been making a challenge to the patent, if other
    competitors knew that that had happened, then they would perceive that to be a
    sign that the patent was weak and that they would leap in" (which,
    paradoxically is exactly the argument the 11th Circuit made in
    deciding that "weak" patents would be more, not less vulnerable if
    the patentee made too generous settlements or payments).  Specifically:

    Although a patent holder may be able
    to escape the jaws of competition by sharing monopoly profits with the first
    one or two generic challengers, those profits will be eaten away as more and
    more generic companies enter the waters by filing their own paragraph IV
    certifications attacking the patent.

    Herbert Hovenkamp, "Sensible
    Antitrust Rules for Pharmaceutical Competition," 39 U.S.F. L. Rev. 11, 25
    (2004).

    The
    government also asserted the "first filer" provisions of the ANDA
    statute (which is a red herring after the 2003 amendments where a first filer
    loses its ability to block later filers by entering into a reverse payment
    settlement agreement), stating that the 180-day exclusivity is "not good in
    and of itself for consumers" due to the delay in price erosion during that
    period.  Justice Breyer seemed
    unconvinced ("that's rather thin"), speaking generally about settled
    antitrust tools and principles and asking the government's lawyer why this
    approach ("Judge, pay attention to the department when it says that these very often can be anticompetitive, and ask the defendant why he's doing it.")
    shouldn't be used in assessing the legality vel non of reverse payment
    settlement agreements.  According to
    Justice Breyer, the government asks the Court to "produce some kind
    of structure — I don't mean to be pejorative, but it's rigid — a whole set of
    complex per se burden of proof rules that I have never seen in other antitrust
    cases," and asks the government to provide the antecedents in antitrust
    law that would support such a regime.  After some colloquy regarding other standards like the "quick look"
    rule of reason, Justice Breyer said:

    [W]hy isn't the government satisfied with an opinion of this Court that
    says, yes, there can be serious anticompetitive effects.  Yes, sometimes there
    are business justifications, so Judge, keep that in mind.  Ask him why he has
    this agreement, ask him what his justification is, and see if there's a less
    restrictive alternative.  In
    other words, it's up to the district court, as in many complex cases, to
    structure their case with advice from the attorneys.

    Mr.
    Stewart responded that this would not provide enough guidance, but Justice
    Breyer rejoined that it is the same guidance as in any other antitrust case
    with regard to anticompetitiveness.  He
    remarked that he has "32 briefs" supporting the government's position
    that the agreements are anticompetitive, and then "four [], maybe five"
    briefs supporting Respondents that say there could be "offsetting
    justifications."  And for Justice
    Breyer, district courts can make these distinctions.

    The
    government countered, saying that its "approach accounts for that,"
    wherein it is the payment that "gives rise to the inference that . . . the
    delay . . . is longer than the period that would otherwise reflect [the generic's]
    best assessment of its likelihood . . . of success in the lawsuit."  There are two ways the government proposes that
    parties to a reverse payment settlement agreement could rebut the presumption
    of illegality:  either by a showing that the payment was not for delay in market
    entry, or that (unlikely in the government's view) even if the payment was for
    delay there is some pro-competitive effect.

    Justice
    Breyer noted that the briefs in support of the Respondents mention at
    least two other possible rebuttals of the government's presumption.  The hypothetical is significant due to
    Justice Breyer's understanding that it is not anticompetitive:

    [B]ecause the person's already in the market thinks that the next year or
    two or three years is worth $100 million a year, and the person who's suing
    thinks it's worth 30 million a year.  And so he says, hey, I have a great idea,
    I'll give him the 30 million and keep the 70.  And . . . that, I don't see why
    that's anticompetitive if that's what's going on.

    The
    other rebuttal perceived by Justice Breyer is when the market is hard to break
    into, and then the brand is helping the generic enter the market in return for
    not challenging the patent (which Justice Breyer thought would be procompetitive).  But he admitted that parsing this out can be a
    nightmare.

    The government blamed any nightmarish aspects of the agreements on the branded and
    generic parties who make them so, and stated that Respondents' position that it
    would be permissible for the branded to delay entry of the generic until patent
    expiry upon the payment of sufficient monies "really shows their
    anticompetitive potential, i.e., that the payment is what skews the decision to
    agree on a time for generic market entry.

    Justice
    Sotomayor then asked the Deputy SG "why is the rule of reason so bad?,"
    apparently agreeing with Justice Breyer that the government is asking the Court
    to erect a completely new structure where traditional antitrust principles
    should work just fine.  She addressed the
    problem with the government's position in terms echoing those identified in the
    Bender White Paper (see "Academic White Paper Rebuts FTC and S. 214"):

    I have difficult[y] . . . understanding why the mere existence of a reverse
    payment . . . presumptively . . . changes the burden from the Plaintiff.  It would
    seem to me that you have to bear the burden . . . of proving that the payment for
    services or the value given was too high.  I don't know why it has to shift to
    the other side.

    While
    never providing a direct response, the government raised "administrative"
    and "conceptual" grounds which
    did not convince Justice Breyer, who believed that making these types of
    determinations would take a district court "probably 3 minutes or less."  The government completed the opening portion
    of its argument by reiterating that the ANDA lawsuit could not have resulted in
    a reverse payment to the generic company, and thus that the existence of the
    payment is enough to raise a presumption of anticompetitive behavior and thus
    to be illegal.

    Respondents'
    attorney Mr. Weinberger began his argument by answering (in the negative)
    Justice Scalia's query regarding whether the Court had ever found an antirust
    violation resulting from a "patent-based restraint[on trade]," with
    the only exceptions being in cases where
    the patentee was acting outside the scope of the patent, such as downstream
    retail price controls.

    Justice
    Sotomayor asked why this isn't the case here, because there is no presumption
    of infringement, so doesn't the settlement raise the presumption that the
    parties are acting outside the scope of the patent?  Mr. Weinberger said no, because there is no
    basis for assessing whether there has been an antitrust violation based on
    whether you could establish in litigation that the patent had been
    infringed.  But Justice Sotomayor opined
    that the Court should not be asked to "accept" that there had been
    infringement under circumstances where the patentee has "voluntarily
    decided not to pursue his rights."  The Justice contrasted the case where the infringer licenses the patent
    and gets the right to sell upon payment to the patentee, with the situation
    here where the patentee pays the generic putative infringer not to sell,
    suggesting to her that the parties are "sharing profits."  She also noted that typical licensing
    settlements for patent infringement suits don't involve reverse payments.

    Justice
    Breyer characterized the government's position to be that reverse payment
    settlement agreements are not per se
    unlawful, but that "they want to cut some kind of line between a per se
    rule and the kitchen sink.  And if you look at the brief supporting you, it is
    the kitchen sink," asking Mr. Weinberger to define the rule.  Mr. Weinberger stated that he didn't think
    there was any "intermediary" test, because "you can't really
    measure whether there were any anticompetitive effects from such a settlement
    agreement without determining what would have happened if the case hadn't
    settled and it would have been litigated"; if the patentee had won there
    would not have been any
    anticompetitive effects.  This was the
    determination of the Second and Federal Circuits in the tamoxifen and Cipro
    cases, respectively, where those courts applied the antitrust "rule of
    reason" test and required the government to establish anticompetitive
    effects, according to Mr. Weinberger.

    Justice
    Kennedy then asked whether the focus should have been on what the generic could
    have lost rather than what the branded gained, and Mr. Weinberger returned to Respondents'
    theme that there would have been no gains if the generics had not prevailed,
    requiring that patent litigation actually ensued and infringement was found (or
    not).

    Justice
    Kagan asked for clarification with her own hypothetical, which quickly
    indicated where her initial inclinations seemed to lie.  According to the Justice, what if there is a
    lawsuit and the defendant says to the patentee, if I win I reduce your profits
    from $100 million to $10 million, but if I go away you continue to make the
    $100 million.  Thus, if the patentee paid
    $25 million to the challenger both parties would be better off, but such an
    arrangement would be anticompetitive and an antitrust violation.  If that is the case, asked the Justice, why
    doesn't that describe the situation before the Court?  She added: "It's clear what's going on
    here is that they're splitting monopoly profits and the person who's going to
    be injured are all the consumers out there" and "I think if we give
    you the rule that you're suggesting we give you, that is going to be the
    outcome because this is going to be the incentive of both the generic and the
    brand name manufacturer in every single case is to split monopoly profits in
    this way to the detriment of all consumers."  (In this, the Justice ignored,
    for the moment, the fact that this hasn't
    happened.)

    In
    response, Mr. Weinberger mentioned the lower entry cost to challenge a patent
    under Hatch-Waxman based on certification alone, because a generic challenger
    does not need to make the actual investment that a competitor would need to
    make in other types of patent infringement litigation.  "And the FTC's own studies have shown
    that it takes a very small chance of winning, something like 4 percent for a
    drug over $130 billion to justify a generic suing a brand name company" he
    reminded the Court.

    Justice
    Sotomayor then raised her own concerns with these agreements.  "The Second Circuit recognized,"
    said the Justice, "even though it accepted your scope of the patent
    [standard], that there was a troubling dynamic in what you're arguing, which is
    that the less sound the patent, the more you're going to hurt consumers because
    those are the cases where the payoff, the sharing of profits is the greatest
    inducement for the patent holder."  Mr.
    Weinberger responded by arguing that this isn't an issue in practice because of
    the "so many potential challengers" to the patent, for all of whom "all
    they have to do is file an ANDA, there are 200 generic companies in this
    industry, that if you try to adopt that strategy of paying the profits of a
    generic, there's going to be a long line of [generics to pay off]."

    Justice
    Kagan disputed this argument based on the first filer/180-day exclusivity provisions
    (which she called a "glitch" in Hatch-Waxman), saying that "once
    the 180-day first filer is bought off, nobody else has the incentive to do this"
    (which may have been the law before 2003 but is not the law now).  Respondents argued that this is not correct "either
    by logic or by reference to actual experience" based on the long lifetimes
    of the drugs, but Justice Kagan stated she understood that "the huge
    percentage of the profits [are made] in the exclusivity period."

    Justice
    Sotomayor then posed the counter question to Mr. Weinberger that she posed to
    the Deputy SG: "what's so bad with banning reverse payment settlements?"  Mr. Weinberger responded that while the
    parties could "always just litigate," there is no incentive for the generic
    not to litigate instead of settling without some financial recompense, i.e., the reverse payment.

    Justice
    Ginsberg raised the concern that the generic is unjustly enriched, a position
    in which Justice Kennedy agreed, to the extent that the generic obtained more
    than what it would have gotten if it won the ANDA litigation.  Justice Ginsberg stated her interpretation of
    the government's position, that generics were getting a windfall, but Mr.
    Weinberger noted that the government has not provided any data or examples of
    such a situation.  Justice Kennedy noted
    that "if the generic wins [the ANDA litigation] the brand companies
    profits are going to go way, way down right away and generic profits are not
    going to be that great.  . . .  [I]f you key
    your payment to what the brand company will make, it's just a much higher
    figure, and a greater danger of unreasonable restraint."  Mr. Weinberger's response was that while this
    may be a hypothetical risk, the reality is that "with the number of
    challenges you have here, which is basically unlimited, that if you put a sign
    around your neck that says, paying off all generic companies their profits,
    whoever wants to challenge my patent come do it, there is going to be a long
    line of people, of companies doing it."  When Justice Kennedy asked whether this wasn't true in every industry,
    Mr. Weinberger reminded him of the low barrier to ANDA status:  "They have
    nothing at risk.  If they lose, they haven't lost any damages.  They just walk
    away."

    In the most cogent few minutes of uninterrupted argument, Mr. Weinberger made the
    case that:

    I think that the antitrust rule should not be fashioned to deal with a
    case on the extreme, which hasn't been shown to happen, which logically from an
    economic point of view is highly unlikely to happen.  And if for some reason
    that starts happening empirically, then Congress — and it is a loophole in
    Hatch-Waxman that is causing that, and there is really no evidence that that
    extreme example has happened –­ then Congress can deal with it, just as it
    dealt with the exclusivity provision.

    Justice
    Sotomayor made the most direct argument against reverse payment settlement
    agreements from the bench:

    I see that as an argument that there is an economic reality in Hatch-Waxman
    that would require us not to apply any rule we choose or accept here to other
    situations, only here.  That's the argument that you're creating for me, that
    there's a different economic reality here that requires a different rule [because] in Hatch-Waxman, Congress decided that there was a benefit for
    generics entering without suffering a potential loss to enter the market more
    quickly [and] any settlement in these cases deprives consumers of the
    potential of having the benefit of an earlier entry.

    Respondents'
    only argument to counter these assertions was that these settlements have not
    hindered the rise in generic entry over the past 10 years, and that requiring
    generics to litigate to conclusion could restrict generic entry.

    In
    rebuttal, the government argued that the outcome of patent litigation is irrelevant
    because antitrust liability comes from the behavior (not the reality) of the
    parties, and that this approach (essentially ignoring the existence of the
    patent) avoids the "conundrum" of determining the outcome of patent
    litigation.  No doubt.

    From the oral argument, reading how the Justices may be leaning is easier for some of the Justices than others.  Justices Sotomayor
    and Kagan (and to a lesser degree, Justice Ginsberg) appeared most enamored of
    policy arguments against these agreements and concerned about their negative
    effects, while the Chief Justice and Justice Thomas' leanings are incapable
    of being determined by their silence.  Justices Scalia, Breyer, and Kennedy were apparently concerned (to
    varying extents) with whether agreeing with the government would upset settled
    antitrust jurisprudence and, paradoxically, itself add another "special"
    set of rules for patent cases.  On
    balance, the Court clearly understood that this case represented another
    instance of the interplay between patent, regulatory, and antitrust law, and
    while individual Justices appeared uncertain about particular provisions and
    their effects (particularly the 180-day exclusivity period) the Court
    questioned both the government and Respondents with equivalent intensity.  Meaning that there is little prospect of
    providing any reasonable conjecture on how this case will come out.

    The
    Court is expected to render its decision by the end of its term in June.

    Patent No. 2,203,040 to Novartis AG (and the associated Supplementary
    Protection Certificate (SPC)) protected rivastigmine, a drug used for the treatment of Alzheimer's
    disease.  The Court of Appeal held the patent to be invalid on the ground of obviousness
    and criticised the over-reliance on the "obvious to try" test for
    assessing obviousness.

    The Patent

    RivastigmineA chiral compound exists as two or more non-superimposable, mirror-image
    chemical structures, the alternative structures being known as enantiomers.  Rivastigmine is the (-)enantiomer of the chiral carbamate compound, N-ethyl-3-[(1-dimethylamino)ethyl]-N-methylphenyl-carbamate.  UK Patent No. 2,203,040 claims rivastigmine.  The compound is marketed in the UK by Novartis as Exelon®,
    and is used for the treatment of
    Alzheimer's disease.

    The High Court Decision

    The High Court assessed
    whether it would have been obvious to a skilled person to select RA7,
    resolve it into its individual enantiomers, and then use the (-) enantiomer as
    a medicinal product for the treatment of Alzheimer's disease.

    A racemic mixture (RA7),
    a mixture of the (+) and (-) enantiomers of N-ethyl-3-[(1-dimethylamino)ethyl]-N-methylphenyl-carbamate,
    was known at the priority date of
    the Patent and had been identified as a potential treatment for Alzheimer's
    disease.

    The UK High Court therefore held that it would
    have been obvious to select the racemic mixture, RA7, to resolve it
    into its individual enantiomers,
    and to use the claimed (-) enantiomer for the treatment of Alzheimer's disease.  The Patent and associated SPC were
    therefore found to be invalid.

    The Court of Appeal
    Decision

    NovartisOn appeal, Novartis argued that the High Court erred in its
    assessment of obviousness.  Novartis argued that that it would not have been "obvious
    to try" and resolve RA7 into the individual enantiomers, nor would there have been
    any expectation that the claimed (-) enantiomer would possess improved biological
    activity compared to the (+) enantiomer.

    The Court of Appeal criticised over-reliance on the obvious to try test in assessing
    inventive step.  The Court of Appeal acknowledged that it might be appropriate
    when assessing inventive step to ask whether it was obvious to try a particular
    route with a reasonable expectation of success.  However, the Decision
    emphasized that such assessment is secondary to the statutory question of
    whether an invention is obvious:

    This is another case in which a
    patentee defending his patent has attempted to analyse a single multi-faceted
    question ("was the invention obvious?") by chopping it up into a
    series of sub-questions, and then treating each of the sub-questions in
    isolation.  . . .  [T]hat is the wrong approach.

    In the present case it was
    clear that the prior art disclosed a group of compounds, including RA7, that were potentially
    useful in treating Alzheimer's disease.  Biological data published in the prior
    art also showed that RA7 was an obvious candidate for further
    development.  The skilled person was also well aware of the common practice at
    the priority date to attempt to resolve racemic compounds at an early stage of the drug development process
    and that there would likely be practical benefits associated with such
    resolution.

    On this evidence the Court
    of Appeal upheld the judgement of the High Court and the patent was held
    invalid.

    Conclusions

    Earlier UK Court of Appeal decisions
    (Generics (UK) Limited v. Daiichi Pharmaceutical Co Ltd and H
    Lundbeck A/S v. Generics (UK) Limited) held patents relating to the
    biologically active enantiomers
    escitalopram and levofloxacin were non-obvious.  However, evidence in these cases indicated that there were particular
    problems with resolving the enantiomers at the relevant priority date.  The
    evidence in the present case indicated that there were no problems encountered
    in resolving RA7 and that resolution could be achieved using
    conventional techniques.

    The present Decision might
    suggest that obtaining patent protection for single enantiomers in the UK is likely to prove difficult if the
    enantiomer was easily resolved from a known racemic mixture.  If data can be produced that demonstrate
    practical difficulties with isolating an enantiomer from a racemic mixture or
    an unexpected therapeutic effect associated with the claimed enantiomer then
    objections of obviousness may be overcome.
