Gene Patents: 2010 Update

Gene Patents: 2010 Update

Authored by Rachel Goh, Medical Student, The University of Melbourne | Victoria, Australia. Edited by Kwanghui Lim

The first half of 2010 saw three events shake the landscape of gene patenting as we know it. As a medical student with research experience, my interest rests in the clinical impact of these developments and its long-term potential benefits to patients. So far, the aftermath continues to have far-reaching consequences for the fields of personalized medicine, biotechnology and intellectual property – which will no doubt carry into 2011.

Myriad and Monsanto

In March, a U.S. district court invalidated (http://graphics8.nytimes.com/packages/pdf/national/20100329_patent_opinion.pdf) several of Myriad Genetic’s patent claims, notably those on isolated BRCA1-2 DNA sequences. Judge R. Sweet ruled that the BRCA gene mutations linked to breast and ovarian cancers do not differ from genes found in nature, and thus were not innovations. Since ‘products of nature’ cannot be patented, this verdict undermines the fundamental basis on which companies file patents: that the act of isolating and purifying the genes makes them different from what is found in nature. This runs contrary to the previously held standpoint of the U.S. Patent and Trademark Office; that individual unmodified genes can be patented. As expected, the biotech industry lobbied against this verdict. They argued that if upheld, the resulting shockwaves would nullify all naturally-occurring gene patents and be detrimental to corporations that have invested heavily in the development of tests for hundreds of diseases. Unsurprisingly, in June, Myriad filed an appeal (http://www.genomicslawreport.com/wp-content/uploads/2010/11/Myriad-Appellant-Brief.pdf) to challenge Judge Sweet’s ruling in a case headed for the U.S. Supreme Court.

Following this, in another suit over a gene patent, the Court of Justice of the European Union ruled against Monsanto Technology LLC, stating reasons similar to those presented by Judge Sweet (http://www.genomicslawreport.com/index.php/2010/07/28/european-court-issues-gene-patent-ruling-against-monsanto-a-myriad-connection/#more-4036). In September, the U.S. Department of Justice also published an amicus brief (http://www.genomicslawreport.com/wp-content/uploads/2010/11/Myriad-Amicus-Brief-US-DOJ.pdf) that threw their weight behind Judge Sweet’s verdict, except for patents which clearly require human ingenuity (such as those used for complementary DNA in therapeutic molecules or DNA-based vectors for therapy). These, they argue, should be retained.

Key Developments in Australia

Myriad’s story is different in Australia. In September, the Cancer Voices Australia v Myriad Genetics litigation took an unexpected turn when (faced with a case that had no upside and significant downside for them) (http://www.genomicslawreport.com/index.php/2010/06/21/myriad-litigation-goes-down-under/) Myriad offered to surrender its BRCA2 patent. Presumably, they sought to preclude a ruling that would prohibit gene patenting altogether. Their stratagem was unsuccessful, and the case is on its way to the Australian Federal Court (although it is now focused specifically on the BRCA1 gene patent). In addition, a private member’s bill (http://www.theaustralian.com.au/news/health-science/unlikely-challenge-to-human-gene-patents/story-e6frg8y6-1225952333147) was introduced last month with the aim of making genes unpatentable. Shortly after, the Australian Senate finally published their long-awaited report on gene patenting (http://www.aph.gov.au/senate/committee/clac_ctte/gene_patents_43/report/index.htm). Containing sixteen recommendations, the report drew on reasoning similar to that of Judge Sweet’s and suggested amendments not dissimilar to those we advocated in our last update. Like us, they proposed that:

·         Patents be restricted to DNA sequences which are in a form that 1) did not previously exist and 2) are an inventive solution to a real world, practical matter.

·         The use of naturally occurring genetic sequences for medical research be exempted from infringement liability.

This ensures that IP Australia are “patenting cures, not DNA” and protects patient interests. The Senate also recommended the formation of an independent patent audit committee and a “transparency register” to outline who owns what biological material. The report will hopefully prevent years of litigation over where the line lies between what is and what is not eligible for patents. A separate inquiry into the private member’s bill is scheduled in mid-2011.

Concerns over Patentable Materials and Synthetic Life

In June, a second significant international development took place – the much-anticipated conclusion to the Bilski v. Kappos case. In an anticlimactic Court ruling (http://www.supremecourt.gov/opinions/09pdf/08-964.pdf), the Supremes supported the Federal Circuit’s judgment that Bilski’s business method was not patent-eligible, but stated that the Federal Circuit’s “machine-or-transformation” test was not the sole test of patentable subject matter. In short, the ruling helped disperse fears that overzealous patent enforcement inhibits innovation, given that the Court has “substantial discretion … to interpret and implement the patent eligibility doctrine in a manner that fosters innovation”. On the other hand, it did little to clear up the confusion over how to evaluate patent eligibility.

The third major development in the first half of this year, touted as more significant than the cloning of Dolly the sheep, was the world-first creation of a synthetic life form. In May, the J. Craig Venter Institute (http://www.guardian.co.uk/science/video/2010/may/20/craig-venter-new-life-form) produced the first living cell to be controlled entirely by a synthetic genome. These custom-designed life forms can be instructed to produce plastics, medicines, fuels or even absorb greenhouse gas emissions and could be the key to combating climate change. They are exactly the types of innovation that fit the criteria for a patent grant. Certainly, the Institute’s US patent (http://portal.uspto.gov/external/portal/pair) reflects the innovative applications of the new technology, specifically for a set of essential genes that produce a synthetic “free-living organism that can grow and replicate” and make either hydrogen or ethanol for industrial fuels. Naturally, this development has reignited the debate over the ethics of gene patenting. The Canadian ETC Group (http://www.telegraph.co.uk/news/uknews/1553919/Man-made-microbe-to-create-endless-biofuel.html), which tracks developments in biotechnology, raised familiar concerns about companies receiving exclusive intellectual rights to the building blocks of life.

Commentary by Rachel Goh:

In my view, business and biotechnology fuel each other. We’ve never questioned whether this is different for gene patenting. Some would have us believe that complete proprietary protection is critical in encouraging biotech companies to invest in genetic innovation. They argue that should limits be placed on gene patenting, the advancement of research and the future of personalised medicine would be stilted. However, it is unclear how much evidence actually supports this concern. The competition among researchers to find diagnostic mutations for cystic fibrosis and other common diseases flourishes, even though no company has exclusivity. Furthermore, few companies actually go to court when claims to gene sequences are violated. It is controversial that firms are claim rights over genetic data that were obtained partly due to open access to the scientific research accomplished by others and often funded by taxpayers.

Thorough assessments are still needed to examine how important gene patents really are for incentivising the development of diagnostic tests. The role of gene patents is also changing within the biotech industry. Diagnostic laboratories are moving away from a dependence on individual gene patenting and towards multiple-genome analyses, with prominent articles (published as early as March, 2010) reporting that: “when hundreds or thousands of genes are being tested at once, patents on each individual gene can become a hindrance to innovation rather than a spur” (http://www.nytimes.com/2010/03/31/business/31gene.html?_r=1&hp). As we begin to move closer towards developing gene therapy and personalized medicine, a multi-genomic approach will become increasingly important and we will face greater concerns about whether the patenting of individual genetic sequences will inhibit follow-on and systemic innovations.
