Zinc Fingers Could Point to Future Cures, But Gene Patents Could Get In The Way

Jake Meyer by Jake Meyer

A December 29th, 2009 article in The New York Times describes a new technique that allows for the editing of human genes.  The technique uses natural agents called "zinc fingers," two loops of protein that can recognize specific sequences of DNA have multiple potential uses.  Zinc fingers could be used in the future to engineer new crop plants, treat human diseases, and to make alterations to sperm or egg cells –- alterations that would be inheritable. 

Zinc fingers can be used to turn on or off a gene at a specific DNA site.  An agent that turns the gene on or off can be linked to the zinc finger, which recognized and attaches to the specific DNA site.  But zinc fingers have another use which makes them a promising technology for gene therapy –- they can cut out and insert DNA from the gene sequence.

FDR’s Cancer and Abe Lincoln’s DNA: What Rules Should Govern “Biohistory?”

Lori Andrews by Lori Andrews

Historians traditionally probed the lives of past presidents by analyzing their speeches, reading their diaries, and tracing the trajectories of their lives.  But now medical and genetic tools have been added to the arsenal of historic inquiry.  And questions have arisen about the ethical and legal ramifications of the emerging field, “biohistory.”

A new book, FDR’s Deadly Secret by neurologist Steven Lomazow and The New York Post reporter Eric Fettmann, hypothesizes that Franklin Delano Roosevelt had cancer.  The authors and came to that conclusion by analyzing photos of small lesion above his eye, thought to be a melanoma.

The assertion is nothing new. For at least half a century, physicians and journalists, including a 1979 Time magazine article, reported on just such a speculation.  But newspaper and blog responses in the past few days are filled with anger about how FDR could have kept this from the public.  There’s even a sense of outrage that his decision-making during World War II might have been impaired due to the spread of the cancer to his brain.  In yesterday’s PostFettman accused FDR of endangering the nation by running for president with this supposed malady.

Irish Supreme Court Says Sperm Donor is Legal Dad: Will the U.S. Follow Suit?

Lori Andrews by Lori Andrews

Last week, the Supreme Court of Ireland stunned the reproductive technology community by holding that a sperm donor had legal rights as a father.  Four of the five justices wrote separate opinions as to why an agreement in advance not to be a donor did not prevent the sperm donor from asserting parental rights.

The case, J. McD v. PL and BM, involved a Lesbian couple who chose a friend as a sperm donor.  He signed an agreement stating that the female couple were the parents and he would have a role akin to that of a "favourite uncle."  When he sought a greater relationship, a lower court ruled against him.  But the Supreme Court of Ireland held that he could assert his legal rights. 

The reasoning used by the various justices was sweeping and could be applied to any situation of donor insemination, not just those involving nontraditional family structures.  Chief Justice Murray, for example, seemed to compare the sperm donor, McD., to a biological mother who gives her child up for adoption. Murray indicated that the sperm donor’s consent to relinquish parental rights before the child is born is suspect. Murray said that a sperm donor, "when faced after birth with the reality of a child… may, quite forseeably, experience strong natural feelings of parental empathy and identity which may overcome previous perceptions…arrived at in the more abstract situation before the child was even conceived….  [A] change of heart may be, as it was in this case, an event which raises issues as to whether in the interests of the child access or guardianship ought to be granted to the father."

In the United States, as in Ireland, the biological parents of a child cannot create a private contract which denies either parent's rights or responsibilities.  To get around the legal precedent that private agreements are non-binding, most American states have adopted sperm donor statutes, generally addressed to married couples, which hold that the consenting husband of the woman who is inseminated is the legal father.  There are several loopholes in the American jurisprudence, however.  A handful of states do not have statutes at all.  Some of the statutes only say the husband is the father and the donor is not, but others just say that the husband is the father without specifically cutting off the donor's parental rights.  Some terminate the donor’s parental rights only when a married woman is inseminated, not a single woman.  So, litigation in which a sperm donor asserts his rights is still a possibility in some states.  In the absence of specific statutory guidance that is directly on point, an American court, like the Irish one, would probably turn to the "best interest of the child" standard. 

And changing cultural norms might convince an American court that children have a right to learn the identity of their biological fathers, the sperm donors.  In the Irish decision, Justice Fennelly pointed out, "Scientific advances have made us aware that our unique genetic make-up derives from two independent but equally unique sources of genetic material. That is the aspect of the welfare of the child which arises."

So, ironically, even at the same time that reproductive technology is making it unnecessary for parents to have a biological connection to their child, genetic technology is telling children that biology matters.  And courts may be willing to grant a sperm donor rights, not just for the benefit of the donor, but for the benefit of the child. 

The Fender Bender Gene: A New Study Suggests Bad Driving May Be Genetically Based

Jake Meyer by Jake Meyer

While driving in holiday traffic you may be cut-off by a motorist who erratically enters your lane without using a turn signal or you may need to suddenly slam on your brakes to avoid another motorist who brakes with no warning.  And you may find yourself honking your horn and shouting "where did you learn to drive?"  But what if bad drivers didn’t learn to drive like bad drivers, but instead were born bad drivers? 

A recent study by neurologist Dr. Steven Cramer at University of California Irvine suggests that bad driving may be in part genetically based, finding that drivers with a certain gene variant performed 20 percent worse on a driving test than drivers without the gene variant. The study looked at the gene associated with the production of a protein called brain-derived neurotrophic factor (BDNF).  BDNF supports communication among brain cells and keeps them functioning optimally.  Previous studies have shown that people with the BDNF gene variant, when engaged in a task, have a smaller portion of their brain active than those with a normal BDNF gene variant. The study put 29 people in a driving simulator – 22 without the gene variant and 7 with the gene variant – and had them drive 15 laps on track with difficult turns and curves.  Four days later, the participant returned to drive the same 15 laps.  The participants with the gene variant did worse on both tests and also remembered less of the track the second time.

Monsanto Hitting a Genetically Engineered Rough Patch

Patrick-Bickleyby Patrick Bickley

Although it may be hard to feel bad for a $44 billion company dominating its industry with over $11 billion in sales last year, poor Monsanto has had a rough couple of months.  Monsanto has dominated the seed market through its sales and licensing of its genetically modified seeds.  In the 1970’s, Monsanto patented a new herbicide called Roundup that quickly killed weeds and any other plants prior to planting seeds.  In the 1990’s, Monsanto isolated a gene, called CPS4, from Roundup resistant bacteria found in the company’s waste ponds and placed the gene into its patented soybeans and corn.  These Roundup Ready seeds allowed farmers to continue using Roundup even after planting.

First, in September, Judge Jeffery S. White in the Northern District of California ruled that the U.S. Department of Agriculture failed to assess the environmental impact of genetically engineered sugar beets before approving the crop for farmers to use, according to The New York Times.  The next issue to be decided in the case is what remedy should be imposed.  One possible option is ban on planting the crops until the Department of Agriculture completes the environmental impact statement.  The ban is possible, even though the plants have already been widely adopted by farmers (one survey indicated that 95% of all sugar beets planted this year were genetically engineered), a ban on planting the crops until an environmental impact statement is complete is possible.  In 2007, a different judge in the Northern District of California ruled that genetically modified alfalfa could no longer be planted until the environmental impact statement was completed.  Today, the statement has still not been completed, and the modified alfalfa is, “with rare exceptions,” not being grown.

Supreme Court Ponders A Method of Keeping Students Awake in Anti-Trust Class and a Method of Whispering to Horses

Jake Meyer by Jake Meyer

On November 9, 2009, the U.S. Supreme Court heard oral arguments in the case Bilski v. Kappos.  This important patent case asks the question: what is the proper test for determining what is patentable subject matter for a process?  Patents are not supposed to be granted on mental processes, but Bilski’s claims are directed to a method of hedging risk in commodities trading, which the Federal Circuit has states is a “process wherein all of the process steps may be performed entirely in the human mind.”

In In re Bilski, the Federal Circuit announced that the proper test to determine whether a process was patentable subject matter under 35 U.S.C. § 101, was the machine-or-transformation test, stating that: a “process is surely patent-eligible under 101 if: (1) it is tied to a particular machine or apparatus, or (2) it transforms a particular article into a different state or thing.”  The Federal Circuit has since applied the machine-or-transformation test in a biotechnology case, Prometheus v. Mayo, which I previously blogged about.

Under the test, the Federal Circuit held that Bilski’s claims were not patentable because the claims were not tied to a machine and did not transform an article into a different state or thing.  Claims such as Bilski’s, are considered “business method” claims, and so the Court was also asked the question “[w]hether the Federal Circuit’s ‘machine-or-transformation’ test for patent eligibility, which effectively forecloses meaningful patent protection to many business methods, contradicts the clear Congressional intent that patents protect ‘method[s] of doing or conducting business.'” 35 U.S.C. § 273.  The Justices made many interesting quotes during the oral argument which shed light on the interesting and fundamental patent law question: what is patentable subject matter?

At oral argument, Bilski’s attorney, J. Michael Jakes, argued for a less rigid rule than the machine-or transformation test.

MR. JAKES: . . . I think the question can be avoided, because we don’t need a rigid test of this type based on machine-or-transformation. The question we are looking at and should be looking at is: Are we trying to patent an abstract idea?

At oral argument, the Justices pushed Bilski’s attorney, J. Michael Jakes, by giving seemingly ludicrous examples of things that would be patentable under a more liberal test that did not require a machine-or-transformation.

JUSTICE BREYER: So you are going to answer this question yes. You know, I have a great, wonderful, really original method of teaching antitrust law, and it kept 80 percent of the students awake. They learned things –
(Laughter.)
JUSTICE BREYER: It was fabulous. And I could probably have reduced it to a set of steps and other teachers could have followed it. That you are going to say is patentable, too?
MR. JAKES: Potentially.

Scalia searched for some historical context.

JUSTICE SCALIA: You know, you mention that there are all these — these new areas that didn’t exist in the past because of modern business and what-not, but there are also areas that existed in the past that don’t exist today. Let’s take training horses. Don’t you think that — that some people, horse whisperers or others, had some, you know, some insights into the best way to train horses? And that should have been patentable on your theory.
MR. JAKES: They might have, yes.
JUSTICE SCALIA: Well, why didn’t anybody patent those things?

Breyer brought up concerns of the costs of patents on information.

JUSTICE BREYER: That’s exactly what I -maybe I can get you to inadvertently help my — my hypothesis you don’t like. That’s why I say it’s inadvertent.
You said there are two things. There are actually four things in the patent law which everyone accepts. There are two that are plus and two that are minus. And the two that are plus is by giving people a monopoly, you get them to produce more. As you said, you get them to disclose.
The two minuses are they charge a higher price, so people use the product less; and moreover, the act of getting permissions and having to get permission can really slow things down and destroy advance. So there is a balance.
In the nineteenth century, they made it one way with respect to machines. Now you’re telling us: Make it today in respect to information. And if you ask
me as a person how to make that balance in respect to information, if I am honest, I have to tell you: I don’t know. And I don’t know whether across the board or in this area or that area patent protection will do no harm or more harm than good.
So that’s the true situation in which I find myself in respect to your argument. And it’s in respect to that, I would say: All right, so what do I do?

Sotomayor was also concerned with the cost patents exact on the free flow of information.

JUSTICE SOTOMAYOR: But a patent limits the free flow of information. It requires licensing fees and other steps, legal steps. So you can’t argue that your definition is improving the free flow of information.

Sotomayor gave some attention to amici’s concern that a broad ruling in Bilski may hurt the biomedical world.

JUSTICE SOTOMAYOR: How about if we say something as simple as patent law doesn’t cover business matters instead of what the Federal circuit has begun to say, which is technology is tied to a machine or a transformation of the substance, but I have no idea what the limits of that ruling will impose in the computer world, in the biomedical world, all of the amici who are talking about how it will destroy industries? If we are unsure about that, wouldn’t the safer practice be simply to say it doesn’t involve business methods?

Justices Breyer and Sotomayor are right to be concerned about the effect of patents on the free flow of information.  This is particularly troublesome when patents are on information itself.  For example, with patents on gene sequences, the “invention” is the information.  It’s the A’s, C’s, T’s, and G’s that make up the sequence that are of value, and the disclosure of this information is meaningless because the patent prevents it from being built upon.

At oral argument in Bilski, the lawyer representing the patent office, Malcolm L. Stewart, argued for keeping the machine or transformation test, but to leave it open to an exception for unforeseen technologies.

MR. STEWART: Well, I think the Court could say — could do essentially what was done in Benson and Flook, namely acknowledge that there had never been a case up to this point in which a process had been held patent eligible that didn’t involve a machine or a transformation. It could leave open the possibility that some new and as yet unforeseen technology could necessitate the creation of an exception.

The government is right to be concerned about limiting unforeseen technologies, and the machine-or-transformation test could be an effective test for determining patentable subject matter of processes.  However, the Federal Circuit’s decision in Prometheus showed that the Federal Circuit considers the machine-or-transformation test to be a low hurdle, by holding that the physical step not central to the claim was transformative.  If the Supreme Court decides to keep the machine-or-transformation test, the Court shall have to give guidance to the Federal Circuit on what is to be considered transformative and what is to be considered a machine or else clever claim drafting can add a computer (machine) or other non-essential step (which could potentially be argued to be transformative) to any process claim and make it patentable, which would come with the high cost of limiting the free flow of information.

From Rabbits to Humans: Transplanting Wombs

SarahBlennerBy Sarah Blenner, JD, MPH

In 2000, the first human womb transplant was attempted in Saudi Arabia.  The transplant failed when the 26 year old woman developed a blood clot and the transplanted uterus had to be removed.  But now scientists believe that they are close to perfecting a reproductive technology that could solve some women’s infertility: transplanting a womb into a woman who lacks a functioning uterus. 

Infertility affects one in six women.  Some women are unable to get pregnant because they either do not have a uterus or do not have a properly functioning uterus.  At least 15,000 women in Britain alone are infertile because of a condition associated with uterine function.  A woman may lack a uterus because she has had a hysterectomy or may not have a properly functioning uterus because of a medical condition, such as intrauterine adhesions, also known as Asherman’s syndrome.  Currently, if women without a properly functioning uterus wish to have children, they must either adopt or turn to surrogacy.  Despite the availability of these alternatives, some women want to bear their own children and are willing to undergo surgery to achieve pregnancy.

CSI Meets PhD: Should Universities Require DNA Testing of Job Applicants?

Lori Andrews by Lori Andrews

If you're applying for a job at the University of Akron, you may have more to worry about than the old adage of publish or perish.  Whether you want to work as a secretary or a tenured professor, a new university policy empowers the college to require job applicants to submit DNA.  Laurie Massie, a spokesperson for the University of Akron, told CBS News that the board decided to include DNA testing in the policy because "there have been national discussions that indicate that in the future, reliance on fingerprinting will diminish and DNA for criminal identification will be the more prominent technology." 

But Massie’s statement obscures the difference between a DNA sample and a fingerprint.  Taking DNA is more intrusive, even if it is just done through a cheek swab.  A recent criminal case, Friedman v. Boucher, 580 F.3d 847 (9th Cir. 2009), found that police exceeded their authority when they subjected an unwilling suspect to a cheek swab.  Plus, DNA contains far more information than does the fingerprint.  Testing an applicant’s DNA could provide information about whether the applicant, while healthy now, was likely to develop a costly-to-treat genetic disease.  Even if the DNA was only used to see if an applicant’s DNA was in the federal DNA databank because he or she had committed a crime, adding employment searches to the investigative searches of the databank would result in even greater backlogs than currently exist.

Motion to Dismiss Denied in Breast Cancer Case: The USPTO is a Defendant in a Case Challenging the Constitutionality of Patents Granted by the USPTO

Jake Meyer by Jake Meyer

November 1, 2009, Judge Sweet of the United States District Court in the Southern District of New York issued an opinion in Association for Molecular Pathology v. United States Patent and Trademark Office.  The plaintiffs in the case, which were previously blogged about here, challenge the constitutionality and validity of patents on the BRCA1 and BRCA2 breast cancer genes owned by Myriad.  The defendants — the U.S. Patent and Trademark Office (USPTO), Myriad Genetics, and the Directors of the Utah Research Foundation — moved to dismiss the case for standing and jurisdictional issues.  Judge Sweet denied all motions to dismiss, finding there was both standing and jurisdiction.

The inclusion of the USPTO as a defendant in this case is unique to this case, as the USPTO has never been a party to a lawsuit in which the constitutionality of patents issued by the USPTO were brought into question.  The USPTO moved to dismiss for lack of subject matter jurisdiction (the USPTO also moved to dismiss for lack of standing) arguing that it had a comprehensive statutory scheme in place to redress violations of the Patent Act.  However, the cases the USPTO cited involved claims that alleged statutory violations that the Patent Act provided a remedy for.  Judge Sweet found that there was no comparable statutory scheme that provided remedies for constitutional violations.  Judge Sweet found that there was subject matter jurisdiction over the USPTO citing the novel circumstances of the action, the absence of any remedy provided in the Patent Act, and the importance of the constitutional rights asserted by the plaintiffs.

The Story of a Sperm with a Bad Heart

Keith Syverson by Keith Syverson

A study published in last week's issue of the Journal of the American Medical Association (JAMA) raises concerns about regulation of sperm banks.  The study describes the case of a 23-year-old man in good health who donated sperm to a U.S. sperm bank almost a hundred times over a two year period.  The sperm bank followed protocols standard in the industry at the time of the donation: doctors gave the donor a comprehensive medical evaluation including a complete personal and family medical history in addition to laboratory testing for communicable diseases. Several years later, a woman inseminated with the donor's sperm gave birth to a child diagnosed with Hypertrophic Cardiomyopathy (HCM) — a heart disease characterized by the thickening of the heart muscle.  The sperm bank notified the donor and all other recipients of his sperm that their children were at risk for HCM.  Twenty-two children were born using the donor's sperm in addition to two children born to the donor's wife.  Five children showed evidence of HCM including one two and a half year old child who died waiting for a heart transplant.

This case study underscores the need for more stringent testing protocols for gamete donation.  The American Society for Reproductive Medicine has published recommendations on genetic screening for gamete donors, but compliance with these guidelines is voluntary.  Studies have shown that most gamete donor agencies do not follow these protocols.  For sperm banks, only half of programs surveyed performed a chromosome analysis and about a quarter of egg donor agencies reported that they do not screen egg donors.  Moreover, the authors of the JAMA article note that it is a surprise that the sperm bank was able to contact the donor and everyone who received the sperm because this is uncommon in the industry.
