Lowell v. Lewis raises the "moral utility" of subject matter for the purposes of patenting, in this case, the patentability of a water pump. In Lowell, the U.S. Patent and Trademark Office claims there are "public policy and morality aspects" of the utility requirement. (Although courts have relied on Lowell in recent years, it is usually in relation to inventions of specious utility, rather than questions of moral utility. In fact, courts have not raised moral utility as a bar to patentability even for inventions that are illegal.)

1859: Darwin publishes Origin of Species
Charles Darwin publishes The Origin of Species.

1925: Scopes Trial: the right to teach evolution
Tennessee v. John Scopes is the first trial to address the teaching of the theory of evolution in U.S. public schools (an issue still very much in debate in 2003). In March of 1925, Tennessee is the first state to outlaw non-Biblical stories of creation, and John Scopes is arrested for teaching the theory of evolution. Decades later (1968), the Supreme Court rules that creationism should not be taught because it is a religious belief, but evolution may be because it is a science.

1942: Supreme Court stops some sterilization, establishes reproductive right
In Skinner v. Oklahoma, the Supreme Court rules that a 1935 law allowing for the forced sterilization of certain kinds of criminals is unconstitutional. (However, Buck v. Bell (1927) remains in force so that the involuntary sterilization of the "feebleminded" is still allowed under the constitution.)

1943: DNA = genes
Avery demonstrates that DNA is the material of genes.

1945: Reports of donor insemination
The British Medical Journal publishes early reports of artificial insemination using donor sperm, raising concerns in both in the press and in Parliament. In 1948, a report from the office of the Archbishop of Canterbury recommends criminalizing artificial insemination that uses donor sperm. Concerned that such action would drive it underground, the government discourages but does not criminalize sperm donation.

1960: Birth-control pill approved
The Food and Drug Administration approves the birth-control pill. An FDA official states "Approval was based on the question of safety.... When the data convinced our experts that the drug meets the requirements of the new drug provisions our own ideas of morality had nothing to do with the case."

1960s: Animal organs transplanted to humans

On learning that her blood contained an extremely rare antibody, Garber sold it to various medical firms for large sums of money, but did not report the sales on her tax returns, for which she was prosecuted. She maintained the right to sell her body.

1980s: Commercial development of federally funded research
Three laws are passed, the Patent and Trademark Amendment Act (commonly known as the Bayh-Doyle Act, 1980), the Stevenson-Wydler Technology Innovation Act (1980), and the Federal Technology Transfer Act (1986), that advance industry/government relations (and expand patent law) by encouraging government agencies and other educational and nonprofit institutions to interact, and to apply for patents on inventions that had federal funding. In addition, the Bayh-Dole act offers tax incentives to companies investing in academic research. The Stevenson-Wydler Act promotes technology transfer by encouraging joint projects. With the Technology Transfer Act, researchers at government facilities, such as the National Institute of Health, can patent their inventions and keep up to $150,000 in annual royalties.

1980: First patent on a living organism
In the Diamond v. Chakrabarty case, the U.S. Supreme Court rules for the first time that living organisms can be patented. In a close and hotly contested decision, the court rules that a bacterium that was genetically engineered to break down oil spills is a "'manufacture' or 'composition of matter'" that met the criteria for patenting. The majority opinion states that the court was "without competence" to judge the merits of arguments that warned of dire consequences if life was ruled patentable. The court's decision opens the door to claims on other living organisms not explicitly included in the Plant Patent Act. Over the last 15 years, the U.S. Patent and Trademark Office (USPTO) has granted more than 400 U.S. patents on higher animals, including pigs, cows and sheep, many genetically modified with human genes. Human-cow embryos have been patented, and in 2001, the University of Missouri was granted a patent on a cloning technique that does not rule out the creation of human embryos. The U.S. Patent and Trademark Office (USPTO) now allows genes to be patented. Over 20,000 genes, 7,810 of them human genes, have been patented in the U.S.

p>1981: Research regulation on humans
The National Research Act of 1974 is revised by the Department of Health and Human Services Services, creating the Common Rule, which requires that institutions adhere to rules of ethical treatment of human research subjects. The rules are adopted in response to the Tuskagee Syphilis Study (a study in which, from 1932 to 1977, 399 African-Americans were denied treatment for syphilis in order to study the disease's effects), a blatant case of unethical human-subject research. The National Research Act also "led to the establishment of the OPRR [now the Office of Human Research Protections] and the National Commission for the Protection of Human Subjects."

1988: Embryo research ethics committee formed
Congress forms the Biomedical Ethics Advisory Committee to make recommendations regarding embryo research.

1988: Biology wins in surrogacy court case
The surrogacy case of "Baby M" is one of the first to come before the courts when surrogate mother Mary Beth Whitehead refuses to surrender custody of the child she carried for another couple. (Whitehead was inseminated with the semen of the intended father; the intended mother was unable to conceive or carry a child.) The New Jersey Supreme Court awards Mr. Stern, the baby's genetic father, and his wife permanent custody, but allows Whitehead to retain some parental and visitation rights because of her biological relationship (genetic and gestational) to the child.

As a federal agency, the Federal Railway Administration falls under the provisions of the U.S. Constitution.

1989: Criminal DNA database created
Virginia is the first state to pass a law requiring convicted sex offenders, all convicted felons (1990) and convicted juveniles (1996) to provide samples for a DNA database. By 1998, all fifty states required certain offenders to provide DNA.

1989: Supreme Court allows criminal DNA banking

1989: Supreme Court rules biology does not equal paternity R
The U.S. Supreme Court rules in Michael H. v. Gerald D. that a man who has fathered the child of a married woman does not have a constitutional right to paternity. The ruling upheld the 1872 California law of presumptive paternity, which said that regardless of biology, the husband of a woman is the father of that woman's child.

1990: First transgenic dairy cow
GenPharm International creates the first transgenic dairy cow, to produce human milk proteins.

Moore v. Regents of the University of California is the first case in the United States to address the issue of who owns the rights to an individual's cells. Diagnosed with leukemia, John Moore has blood and bone marrow withdrawn for medical tests. Suspicious of repeated requests to give samples because he had already been cured, Moore discovers that his doctors have patented a cell line derived from his cells and sues. The California Supreme Court finds that Moore's doctor did not obtain proper informed consent, but that Moore cannot claim property rights over his body.

1990: Reproductive Technology in the UK regulated
The Human Fertilization and Embryology Authority is created in the United Kingdom to act as a licensing authority regulating reproductive technology.

1990: Reproductive right to IVF protected
In Lifchez v. Hartigan, a federal court struck down an Illinois Abortion Law as being an impermissible infringement on a woman's fundamental right to privacy and reproductive freedom. The court found the law vague because it failed to distinguish between prohibited "experimental" and permissible "therapeutic" medical procedures, thereby infringing on a woman's right to use medically assisted reproductive technologies such as in vitro fertilization, embryo donation or embryo freezing. Additionally, the court held that the use of these and other technologies were encompassed within a woman's fundamental right to privacy and reproductive freedom.

1990: Human Genome Project proposed

Workers sue the federally run Lawrence Berkeley Laboratory for testing them without their knowledge for sickle cell anemia, syphilis and pregnancy, alleging that the tests violate their constitutional right to privacy, the Americans with Disabilities Act and Title VII of the Civil Rights Act. The U.S. Court of Appeals for the Ninth Circuit ultimately agrees in 1998, saying that an employee may not be tested for such highly private and sensitive medical information without his knowledge and that the testing violated Civil Rights Act because black and female—and not white male—employees were subjected to tests (for sickle cell anemia and pregnancy, respectively). However, the court dismissed the ADA claim, saying that the scope of pre-placement exams may be "unlimited" under the ADA.

1996: Federal law outlaws some genetic discrimination

1997: World's first cytoplasmic transfer birth
The first child is born using a new assisted reproduction procedure,cytoplasmic transfer,at the Institute for Reproductive Medicine and Science of Saint Barnabas Medical Center in N.J. In cytoplasmic transfer, cytoplasm from a donor egg is injected into the egg of a woman who is considered unable to sustain a pregnancy, but would like to have a genetic connection to a child. Because cytoplasm has mitochondrial DNA, the resulting embryo has been shown to carry genetic material (DNA) from the sperm and from both women, the egg donor and the infertile woman. Commentators call cytoplasmic transfer the first inroad into germline genetic manipulation (manipulation that affects future generations.) The FDA has since claimed jurisdiction over the procedure, calling it a kind of gene manipulation.

1998: First genetic privacy ruling
The U.S. Court of Appeals for the Ninth Circuit (the highest level of court below the U.S. Supreme Court) is the first to address genetic privacy. Lawrence Berkeley Laboratory, a federal laboratory at the University of California, for years conducted genetic tests on all employees without their explicit permission. Blood and urine samples that were taken were tested for syphilis; some were also tested for sickle cell anemia (a genetic disease) and pregnancy. In 1995, workers sued, alleging that the tests violated their federal constitutional right to privacy, and their right to privacy under the California Constitution, the Americans with Disabilities Act (ADA) and Title VII of the Civil Rights Act of 1964. The Court ultimately agreed in 1998, saying that an employee may not be tested for such highly private and sensitive medical information without his knowledge. However, the court dismissed the ADA claim, saying that the scope of pre-placement exams may be "unlimited" under the ADA.

The U.S. Equal Employment Opportunity Commission (EEOC) brings suit against the Burlington Northern Santa Fe Railway (BNSF) for doing secret genetic testing on its employees. The employees had filed claims for work-related injuries based on carpal tunnel syndrome. The EEOC argues that the test is illegal because it did not meet the ADA's requirement that it be work-related and of business necessity, and that certain employees are being illegally retaliated against for refusing to submit to the test. Burlington Northern Santa Fe agrees to pay $2.2 million to settle charges with legal issues still unresolved. (Note: There is no known gene responsible for carpal tunnel syndrome. BNSF used an inappropriate test for their stated goal.)
