Ethics, regulation and intellectual property

Biotechnology's power raises questions no experiment can settle: who decides what should be made, who bears the risks, who owns the results and who gets the benefits. This final lesson covers the institutions and rules that answer those questions in practice: biosafety and biosecurity, the regulators who approve products, the patent system and its limits on living things and genes, the ethics of consent and benefit sharing, and the particular debates over genome editing, agricultural biotechnology and the price of biologics. It ends with Lena's capstone task, a briefing note that forces her to weigh several of these at once.

Biosafety and biosecurity

Biosafety protects people and the environment from accidental exposure. Organisms are placed in risk groups by how dangerous they are, and laboratories work at matching containment levels, from level 1 for organisms not known to cause disease in healthy adults up to level 4 for agents that cause severe disease with no treatment. Each level adds requirements: practices, equipment such as biological safety cabinets, and facility features such as directional airflow and airlocks. In Canada, the Human Pathogens and Toxins Act and the Health of Animals Act are implemented through the Canadian Biosafety Standard, and facilities handling regulated pathogens need a licence from the Public Health Agency of Canada.

Biosecurity protects against deliberate misuse. It covers physical security and inventories of dangerous agents, screening of personnel, screening of synthetic DNA orders, export controls, and oversight of research whose results could be misused. Research that could reasonably be expected to increase the transmissibility, virulence or evasiveness of a dangerous pathogen attracts additional review, and policies on such work have been revised repeatedly, reflecting continuing disagreement about how to weigh the benefits for preparedness against the risks of an accident or misuse. The Biological Weapons Convention, in force since 1975, prohibits developing or stockpiling biological weapons but has no verification mechanism, so much of the practical burden falls on national rules and on scientists' own norms, in the tradition Asilomar began.

Who approves what

Regulation divides by product and by jurisdiction. In Canada, Health Canada approves drugs, biologics and medical devices, and assesses novel foods, including foods from engineered or edited plants, under the Food and Drugs Act and its regulations. The CFIA assesses environmental release of plants with novel traits, livestock feeds and veterinary biologics. New organisms and chemicals not covered by other acts fall under the New Substances Notification Regulations of the Canadian Environmental Protection Act, administered with Environment and Climate Change Canada.

Clinical research has its own layer. Trials need approval from a research ethics board, called an institutional review board in the United States, and from the drug regulator, and must be registered publicly. Informed consent must be documented. Good clinical practice standards govern how trials are run, and participants' privacy is protected by provincial health information laws and PIPEDA. For medicines made from human cells and tissues, additional rules govern donor screening and traceability.

Patents and living things

Patents give an inventor the right to stop others making, using or selling an invention for a limited term, usually 20 years from filing, in exchange for publishing how it works. Whether living things could be patented was settled for the United States in Diamond v. Chakrabarty in 1980, when the Supreme Court held that a bacterium engineered to break down oil was patentable because it was a product of human ingenuity, not a product of nature. Canada took a narrower path: in Harvard College v. Canada in 2002 the Supreme Court held that a transgenic mouse was not patentable, because a higher life form is not a manufacture or composition of matter, while in Monsanto v. Schmeiser in 2004 it held that patents on genes and cells are enforceable even when the gene is present in a plant the patent does not itself cover.

Gene patents have narrowed. In Association for Molecular Pathology v. Myriad Genetics in 2013, the United States Supreme Court held that isolated natural DNA is not patent eligible because it is a product of nature, while complementary DNA, which does not occur naturally, is. The decision ended exclusive control of testing for the BRCA1 and BRCA2 genes and lowered the cost of such tests. Methods, vectors, engineered sequences, cell lines and manufacturing processes remain patentable, and modern biotechnology patents focus on these.

Patents interact awkwardly with research tools. The foundational CRISPR patents were disputed for years between the University of California and the Broad Institute, with different outcomes in different jurisdictions, complicating licensing. Some tools are shared instead: the Registry of Standard Biological Parts, open-source plasmid repositories and patent pools lower barriers, and humanitarian licences allow royalty-free use in low-income countries, as for Golden Rice. Plant varieties have their own system, plant breeders' rights under the international UPOV convention, which traditionally allowed farmers to save seed, a right narrowed in later versions and often further restricted by contracts.

Consent, privacy and benefit sharing

Biological samples come from people, and people have interests in them. The case of Henrietta Lacks is the best known: cells taken without her knowledge during cancer treatment in 1951 became the HeLa line, used in tens of thousands of studies, while her family knew nothing for decades and received nothing. Modern research ethics requires informed consent for research use of samples and data, with debates about how broad a consent can be when future uses are unknown. Genomic data are peculiarly identifying and reveal information about relatives who never consented, which is why genomic databases use controlled access and why Canada's Genetic Non-Discrimination Act of 2017, upheld by the Supreme Court in 2020, prohibits requiring genetic tests or disclosure as a condition of contracts or services.

Benefit sharing applies the same idea to countries and communities. The Convention on Biological Diversity and its Nagoya Protocol establish that states have sovereign rights over their genetic resources, that access requires prior informed consent and that benefits must be shared on agreed terms. The rules extend uneasily to digital sequence information, which can be used without physical access to a sample, a question that negotiations have continued to address. For Indigenous peoples, principles of data sovereignty, such as the OCAP principles in Canada, assert community control over how samples and data about them are collected and used.

Three live debates

Genome editing in people divides cleanly along one line. Somatic editing, which affects only the patient, is treated like other advanced therapies and judged on safety and efficacy; the main ethical problems are cost and access, since therapies priced in the millions reach few of the people who need them, most of whom live in countries that cannot afford them. Heritable germline editing, which changes descendants, is prohibited in many countries and rejected internationally for now, both because safety cannot be shown and because consent from future generations is impossible. Between the two sit uses such as editing to prevent rather than treat disease, and questions about where therapy ends and enhancement begins.

Agricultural biotechnology shows how much of the debate is not about safety. Science academy reviews have found foods from marketed engineered crops as safe as conventional ones (lesson 9), yet opposition persists, grounded in concerns about corporate concentration, patents and seed saving, effects on smallholders, environmental effects of the farming systems the traits support, and a wish to choose what one eats, which labelling policies address differently in different countries. Treating these as scientific errors to be corrected misreads them; they are questions about who controls food production.

Pricing and access run through the whole field. Biologics are expensive to develop and make, and prices for cell and gene therapies have reached the millions. Defenders argue that high prices fund the research that produced the therapy and reflect lifelong benefit from a single treatment; critics note the public funding behind much of the underlying science, the role of marketing and patent strategies in extending exclusivity, and that insulin, nearly a century old, remained unaffordable for many patients until policy intervened. Biosimilars and public manufacturing capacity are among the proposed remedies, with their own costs and limits.

How to think about a new application

A workable habit for judging a new biotechnology is to ask five questions in order. What exactly is the product, and what does the evidence show about its risks and benefits? Who bears the risks, and who gets the benefits? What rules apply, and are they about the product or the process? Who owns what, and does that ownership block anyone who needs access? And what would make the decision reversible if it turns out to be wrong? The answers do not follow from biology alone, which is why regulation, ethics and law are part of a biotechnologist's training rather than an afterthought.

Lena's co-op term ends with the briefing note. She has built a plasmid, watched a 2,000 litre culture grow, purified an antibody, validated a test strip, read three countries' rules and written a recommendation that she knows the board may not take. That mixture, of bench skill, quantitative judgement and attention to the rules and interests around the science, is what working in biotechnology actually involves.
