Since the late 1980s a number of studies have predicted the significant adverse impacts of climate change upon world food supplies both generally 1 and in relation to developing countries in particular. 2 The key findings of the 2001 Third Assessment Report of the United Nation's Intergovernmental Panel on Climate Change (IPCC) 3 with respect to food, fibre, forestry and fisheries were that: CO2 effect may be relatively greater (compared to that for irrigated crops) for crops under moisture stress; and crop yields would decline in both the tropics and mid to high latitudes with associated declines in plant health. The Report observed the possibility of increases in diseases and algal blooms in the aquaculture industry as seawater temperatures rise. The conclusions of the Panel's Fourth Assessment Report (2007) was that ‘climate change alone is estimated to increase the number of undernourished people to between 40 million and 170 million’ and ‘is likely to further shift the regional focus of food insecurity to sub-Saharan Africa’ such that ‘by 2080, about 75% of all people at risk of hunger are estimated to live in this region’. 4 A number of studies have highlighted the influence of climate change upon the development of weeds, insect pests and crop diseases 5 and the ways in which plants can be engineered to withstand salinity 6 and aridity. 7
These agricultural stresses arising from climate change present opportunities for innovators. IPRs have been identified as a means for incentivizing the development of CO2 and N2O abatement strategies through the management of animal feed to alter the rumen microbial population and its activity. 8 Similarly, computer software decision support tools, based on biophysical models of the agronomic system, have been identified as offering considerable scope to reduce N2O emissions from broad acre agriculture and emissions from wet rice cultivation by optimizing management of agricultural inputs such as fertilizers. 9 At the genomic level, climate change has led to the identification and patenting of stress-tolerant genes.
2 INTERNATIONAL INTELLECTUAL PROPERTY INFRASTRUCTURE
The global commercial significance of climate technologies is assured by the global reach of the international intellectual property (IP) regime. Members of the World Trade Organization (WTO), which include some 153 countries as of 23 July 2008, 10 are obliged to introduce IP laws which implement the norms prescribed by the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (‘TRIPS Agreement’). Key provisions in the present context are Article 23.1 which provides that ‘patents shall be available for any inventions, whether products or processes, in all fields of technology, provided that they are new, involve an inventive step and are capable of industrial application’. This provision requires also that ‘patents shall be available and patent rights enjoyable without discrimination as to the … field of technology’. The effect of this provision is to establish a patenting regime which extends to all WTO Members. Additionally, Article 27.3(b) of the TRIPS Agreement requires that WTO Members ‘shall provide for the protection of plant varieties either by patents or by an effective sui generis system or by any combination thereof’.
Although the TRIPS Agreement does not prescribe a sui generis system for the protection of plant varieties, most countries have adopted the 1991 version of the International Convention for the Protection of New Varieties of Plants (UPOV). Thus to 15 January 2011 the UPOV Convention has 70 signatories, with 41 of those joining after 1 January 1995. 11 Despite numerous commentaries and proposals for the adoption of alternative sui generis models, 12 only a few countries have adopted alternatives to UPOV. One of the reasons why countries have tended to adopt UPOV 1991, rather than crafting a sui generis alternative, is that the IPR chapters in the free trade agreements (‘FTAs’), signed since the 1990s by the USA and the EU with their various bilateral partners, includes the obligation to subscribe to the 1991 version of UPOV. UPOV provides for the protection of new plant varieties which are ‘distinct’, ‘uniform’ and ‘stable’. Excepted from protection under the 1978 version of UPOV, was propagating material which had been harvested by farmers and retained for further planting or for sale. Article 15 (2) of the 1991 version of the UPOV Convention confined this seed saving exception to the use of saved material for propagating purposes in farmers' own holdings and in reasonable quantities. UPOV 1991 also permits the use of protected varieties for the purpose of breeding new varieties. As is indicated below, where a new variety can be patented, the seed saving and breeding exceptions become irrelevant.
3 PATENTING OF DNA
The modern biotechnological revolution has enabled the engineering of desirable genetic traits from useful local species. These include: (i) pest control traits such as insect, virus and nematode resistance, as well as herbicide tolerance, and post-harvest traits such as delayed ripening of spoilage prone fruits; (ii) agronomic traits such as nitrogen fixation and utilization, restricted branching, environmental stress tolerance, and male and/or seed sterility for hybrid systems; and (iii) output traits such as plant colour and vitamin enrichment. The production of transgenic plants has become possible through the development of a number of enabling and transformation technologies.
A key issue around the patenting of genetic resources was whether a DNA sequence could be characterized as an ‘invention’. In the early history of patent law an invention was thought to involve some kind of technical innovation and a distinction was drawn between patentable inventions and non-patentable discoveries. The US Supreme Court in its 1980 determination, Diamond v Chakrabarty, 13 held in a 4:3 majority decision that a bacterium genetically engineered to degrade crude oil was an invention. This decision provided the legal underpinning for the US biotechnology industry. The European Parliament's belated response in 1998 was its Biotechnology Directive 14 which provided in Article 3.2 that ‘biological material which is isolated from its natural environment or produced by means of a technical process is deemed to be an invention even if this material previously occurred in nature’.
The patentability of genetic materials and gene fragments, such as expressed sequence tags (ESTs) and single nucleotide polymorphisms (SNPs), as well as enabling gene-based technologies, led to what has been described as a ‘genomic gold rush’ in the 1990s, as vast numbers of gene-based patent applications were filed, particularly in the USA. 15 Significant misgivings were expressed by numerous commentators. Probably the most influential among these were HelIer and Eisenberg who suggested that genetic research tool patents could create a ‘tragedy of the anticommons’ in which multiple patent owners would tie-up genetic materials in a thicket of IP patent rights. 16 This was perceived to be a particular problem for the genetic improvement of crops since this is an incremental process and each new patent would constrain the ‘freedom to operate’ particularly of public agricultural research institutes. 17
Arguably, this gold rush has been brought to an end, at least in the USA, by the In re Fisher 18 2005 decision of the US Court of Appeals for the Federal Circuit which upheld a ruling by the US Board of Patent Appeals and Interferences refusing to allow patent applications made on behalf of Monsanto Co on five ESTs encoding protein and protein fragments in maize plants grown by the Asgrow Seed Company of Des Moines, Iowa. 19 It is suggested that that the Fisher case was used by Monsanto Co, a significant downstream user of research tools, to urge upon the Court a higher patentability standard in order to eliminate the thousands of research tool patents which were cluttering research efforts. 20 Mainly for this reason, the case attracted amicus briefs filed by academic institutions as well as major biotechnology and pharmaceutical companies. The Board of Patent Appeals and Interferences was unable to identify any ‘substantial utility’ or usefulness in the application for patentability of the ESTs. The Appeal Court agreed with this approach, stating that claimed inventions ‘ought to have a specific and substantial utility’ to satisfy the requirements of the US patent statute. The Court observed that the application comprised asserted uses based upon ‘merely hypothetical possibilities’ which had not yet been achieved in the real world. As the applicant did not identify the function for the underlying protein-encoding genes, the Court held that ‘the claimed ESTs have not been researched and understood to the point of providing an immediate, well defined, real-world benefit to the public meriting the grant of a patent’. 21
Although this decision imposed a higher patent standard, which might result in the invalidation of previously granted patents over research tools, this was not specifically addressed by the Court. However, it has been optimistically suggested that ‘academic researchers as well as a considerable portion of the biotechnology and pharmaceutical industry will be satisfied by this judgment as it should reduce the number of parasite patents on gene sequences, in the United States’. 22
A recent US case which has raised the very question of the patentability of genetic material is Association for Molecular Pathology v USPTO in which a Judge of the United States District Court for the Southern District of New York delivered a summary judgment which invalidated patents related to the BRCA 1 and 2 breast and ovarian cancer susceptibility genes, which had been held by Myriad Genetics. 23 The Judge held that the claims to DNA sequences in isolation were held to be insufficiently distinct from naturally occurring genes in the body and were thus products of nature rather than inventions. Significantly, he concluded that ‘purification of a product of nature, without more, could not transform it into patentable subject matter. Rather, the purified product must possess “markedly different characteristics” in order to satisfy the requirements’. 24 In his search for ‘markedly different characteristics’ the Judge focused on the function of a gene. He observed that DNA represents ‘the physical embodiment of biological information, distinct in its essential characteristics from any other chemical found in nature and that DNA in an “isolated” form alters neither this fundamental quality as it exists in the body not the information it encodes’. 25
This decision was successfully appealed to the US Court of Appeals for the Federal Circuit (CAFC) in Washington, DC, which published its decision in August 2011. 26 Circuit Judge Lourie, giving the opinion for the Court, considered that the district court had fallen into error in considering, not whether the isolated DNAs were markedly different from naturally occurring DNAs, but rather whether they had the same informational content as native DNA sequences. He pointed out that:
Nevertheless, the CAFC considered that the district court was correct in holding that Myriad's claims directed to comparing and analysing gene sequences were not patentable, as these claims contained no transformative steps and covered only patent ineligible abstract steps. Circuit Judge Moore, concurring in part, noted that the isolation of a DNA sequence is more than separating out impurities, explaining that ‘the isolated DNA is a distinct molecule with different physical characteristics than the naturally occurring polymer containing the corresponding sequence in nature’. 28 According to Circuit Judge Moore, the fact that human action had ‘whittled the chromosomal DNA molecule down’ to a shortened version of its natural self, ‘defining the parts to be retained and discarded’ rendered it ‘entirely different’ from the naturally occurring gene from which it was obtained. 29 Circuit Judge Moore explained that whilst she might conclude that an isolated DNA sequence that includes most or all of a gene was not patentable subject matter if she was approaching the factual matrix from a blank canvas, this was not in fact the case as there was a ‘substantial historical background’ with the courts having been authorized by Congress to approach the issue of patentable subject matter expansively. Established practice had been to allow patents on isolated DNA sequences, such patents having being allowed by the USPTO for ‘decades’ according to the Judge. Accordingly, the Judge explained that she considered that ‘we must be particularly wary of expanding the judicial exception to patentable subject matter where both settled expectations and extensive property rights are involved. Combined with my belief that we should defer to Congress, these settled expectations tip the scale in favor of patentability.’ 30 Both the plaintiffs and the defendants in this litigation have filed petitions for a rehearing of the case by the Circuit Court of Appeals. 31
Adopting this approach, the district court disparaged the patent eligibility of isolated DNA molecules because their genetic function is to transmit information. We disagree, as it is the distinctive nature of DNA molecules as isolated compositions of matter that determines their patent eligibility rather than their physiological use or benefit. Uses of chemical substances may be relevant to the non-obviousness of these substances or to method claims embodying those uses, but the patent eligibility of an isolated DNA is not negated because it has similar informational properties to a different, more complex natural material that embodies it. 27
4 DNA PATENTING AND AGRICULTURE
The cultivation by farmers of GM crops has on occasion led to IP liability, where genetically modified (GM) seed is patented and the cultivation of that seed by the patentee is unauthorized. The cases are divided between those where farmers knowingly cultivate patented GM seed and those where the cultivation of patented seed is apparently inadvertent, for example, where crops are apparently pollinated by wind or insect-borne pollen.
An example of the first category of case is Monsanto Co v Scruggs, 32 which concerned Monsanto's patented Roundup Ready (‘RuR’) glyphosate tolerant seeds. This was licensed to seed companies, who were obliged to sell the seed to growers who signed technology licence agreements acknowledging Monsanto's patent, and on condition that they could only be used by growers for a single commercial crop, that is, growers could not save seed produced from a harvested crop for replanting during the following growing season. Scruggs, who had not signed a technology licensing agreement, purchased a small quantity of RuR soybeans and cotton seeds, which were cultivated and from which he saved seed for further plantings. The Court decided that Monsanto's patent had been infringed by Scruggs, rejecting his defence that neither Monsanto's biotechnology nor the plants in their fields were covered by the patent and that the first sale of the seed embodying the invention exhausted the patent rights of Monsanto. The Court noted that Monsanto never made an unrestricted sale of its seed technology, as it licensed its technology to seed companies with a proviso: subsequent sales of seed containing its transgenic trait must be limited to growers who obtained a licence from Monsanto and for only a single growing season. 33
A recent variant of these facts occurred in Monsanto Co v Bowman 34 where a farmer, Bowman, purchased commodity seeds from a local grain elevator which were not subject to a technology agreement. Following the application of glyphosate to the crops grown from these seeds, Bowman identified those which were glyphosate resistant and these were saved and re-planted in subsequent years, which enabled Bowman to use glyphosate-based herbicide. Monsanto filed a patent infringement claim against Bowman, and, in September 2009, the district court in Indiana granted summary judgment on patent infringement for Monsanto. Bowman appealed to the Court of Appeals for the Federal Circuit. Bowman argued that Monsanto's patent rights were exhausted under the first sale doctrine in relation to all second-generation Roundup Ready soybean seeds that were present in the grain elevators. He cited the 2008 Supreme Court case of Quanta Computer, Inc. v LG Electronics, Inc. 35 In this case the Supreme Court held that sales of products that ‘substantially embody’ the disputed patents will also be considered sales that exhaust the patent right. Bowman argued that the Court should hold that subsequent generations of the seeds are ‘substantial embodiments’ of the first generation seeds, and thus the sales of these seeds would be exhausting sales. The Appeal Court held that even if Monsanto's patent rights in the commodity seeds were exhausted, such a conclusion would be of no consequence, because once a grower, like Bowman, planted the commodity seeds containing Monsanto's RuR technology and the next generation of seeds developed, the grower had created a newly infringing article. 36 The Court observed that: ‘The fact that a patented technology can replicate itself does not give a purchaser the right to use replicated copies of the technology. Applying the first sale doctrine to subsequent generations of self-replicating technology would eviscerate the rights of the patent holder.’ 37
A case of apparently inadvertent infringement is illustrated by the Canadian litigation between Monsanto Canada, Inc and a farmer, Percy Schmeiser. Schmeiser grew canola commercially in Saskatchewan. He had never purchased Monsanto's patented RuR canola nor did he obtain a licence to plant it. Yet, in 1998, tests revealed that 95 to 98 per cent of his 1000 acres of canola crop was made up of RuR plants. The origin of the plants is unclear. They may have been derived from RuR seed that blew onto or near Schmeiser's land. Monsanto brought an action for patent infringement. In finding patent infringement the trial judge ruled that the growth of the seed, reproducing the patented gene and cell, and sale of the harvested crop, constituted taking the essence of Monsanto's invention and using it without permission, and in so doing infringed the patent. 38 By a majority of 5:4 the Federal Court of Appeal ruled that Schmeiser's saving and planting the seed, then harvesting and selling plants that contained the patented cells and genes appeared to the Court, on a common-sense view, to constitute ‘utilization’ of the patented material for production and advantage, within the meaning of s 42 the Canadian Patent Act. 39 The argument that the infringing seed had merely grown as the result of wind pollination, or through the pollinating activities of birds and bees was rejected by the majority Judges as denying ‘the realities of modern agriculture’. 40 What was at stake in this case was sowing and cultivation, ‘which necessarily involves deliberate and careful activity on the part of the farmer’. 41 They noted that he had actively cultivated RuR canola as part of his business operations, thus in light of all of the relevant considerations, Schmeiser had used the patented genes and cells, and infringement was established.
5 PATENTING OF STRESS-TOLERANT GENES
The litigation referred to in the immediately preceding section illustrates some of the implications of DNA patenting in modern agriculture, both in its impact upon farmers and also its implications for the commodification of DNA. This section examines DNA patenting and climate-change agriculture. Somvanshi in a 2008 study identified 30 patents relating to drought tolerant genes. 42 These included: (i) patents related to Proline biosynthesis; 43 (ii) patented dehydration responsive element binding factors (DREB) and C-repeat sequences binding factors (CBF); 44 (iii) patents related to Protein Kinases; 45 (iv) various patents awarded for transcription factors involved in improving drought stress tolerance in plants; 46 and (v) patents related to miscellaneous drought tolerance genes. 47 A 2008 study by the ETC Group 48 identified 55 patent ‘families’ 49 (a total of 532 patent documents) that were applied for and/or granted to a number of biotechnology companies on so-called ‘climate-ready’ genes at patent offices around the world. 50 Its 2010 update of this study ‘examined patents containing claims concerned with abiotic stress tolerance (ie traits related to environmental stress, such as drought, salinity, heat, cold, chilling, freezing, nutrient levels, high light intensity, ozone and anaerobic stresses’. 51 It noted ‘a dramatic upsurge in the number of patents published (both applications and issued patents) related to ‘climate-ready’ genetically engineered crops from June 30 2008 to June 30 2010, identifying 262 patent families and 1663 patent documents. 52
6 DEBATE ON THE ROLE OF CORPORATIONS IN THE PATENTING OF STRESS TOLERANT GENES
The 2008 ETC report was subjected to a close analysis by Dr Carol Nottenburg, 53 the Principal of a US Patent firm, and it is useful to examine the claims and counter-claims to identify the significant elements of the debate about the patenting of stress tolerant genes, as her comments are equally applicable to the 2010 ETC report. The ETC report stated that the so-called ‘Gene Giants’, exemplified by BASF, Bayer, DuPont, Monsanto and Syngenta ‘are staking sweeping patent claims on genes related to environmental stresses’ in patent offices around the world. Dr Nottenburg points out that the patenting of gene sequences is not permitted in a number of developing countries, including Andean countries, and an examination of the patents which are identified in the 2008 report have been sought in Argentina, Brazil and China, leaving more than 200 countries ‘in which these patent applications will never be pertinent’.
Dr Nottenburg also pointed out that the number of patent families is the better indicator of the incidence of the patenting of stress-tolerant genes, than patent filings. This is certainly the case, as a number of filings are duplicated in different countries. The 2010 report identifies some 262 patent families which is a considerable advance on the 55 identified in the 2008 report. However, it should be noted that even a small number of patent families can have a considerable political impact. For example, if the number of biopiracy incidents was totalled, they would probably not exceed around 20 causes célèbres.
The 2008 report is critical of over-broad patent claims, but Dr Nottenburg considers this to be a matter dictated by the ‘eye of the beholder’, and in one case involved an error in the published patent document. She concludes that ‘visions of gene-grabbing and holding farmers hostage are unwarranted’. A particular problem had been that patent applicants had been allowed to make bulk claims in relation to genetic material of which the use had not yet been identified. However, the 2010 report concedes that in 2001 the USPTO put a brake on ‘bulk claims’ by issuing new guidelines requiring that claimed inventions must have ‘well-established’ utility and that in 2007 the USPTO limited bulk claims by notifying its patent examiners that they had the option of restricting claims to only a single nucleotide sequence in each patent application. 54
The 2010 report of the ETC contrasts the ownership of 9 per cent patent families by public sector institutions (9 per cent of the total) with the private sector which holds 91 per cent of the total. As is the case with biotechnological patenting generally, proprietary biotechnologies are concentrated in the same few corporations. 55 The 2010 report points out that ‘just three companies – DuPont, BASF, Monsanto – account for two-thirds (173 or 66%) of the total’. This level of market concentration gives cause for concern to those who espouse the positive role of competition.
In addition to the possible adverse impacts this market concentration might have upon the vigour of competition, the market dominance of these private corporations also has an important influence upon the sort of biotechnological research which is undertaken. For example, to what extent will the dominance of private corporations in biomedical and agricultural research direct that research towards Northern concerns away from Southern food priorities. 56 It has been estimated that only 1 per cent of the research and development budgets of multinational corporations is spent on crops likely to be useful in the developing world. 57 Almost entirely neglected by these corporations are the five most important crops of the poorest, arid countries – sorghum, millet, pigeon pea, chickpea and groundnut. 58
7 COMPETITION IMPLICATIONS
The UN's Special Rapporteur on the Right to Food, in his 2008 Report warned that:
His 2009 Report added that the development of IPRs on agriculture would lead to transfers of resources from technology users to technology producers, both within States and between States and that the oligopolistic structure of the input providers' market could result in poor farmers being deprived of access to productive resources essential for their livelihoods, leading to increases in food prices. 60
[E]xtending patents to plant varieties … would accelerate the ‘verticalization’ of the food production chain, as agricultural producers would become dependent on the prices set by companies for the seeds on which they have patents and would be denied the traditional right to sell and exchange seeds among themselves, as well as to save part of their crops in order to retain seeds for the next planting season – either as a consequence of the protection of patents or by the use of ‘technology use agreements’ by companies selling seeds. 59
The application of IPRs to genetic resources has become a pronounced feature of agricultural innovation in the past decade. The Food and Agriculture Organization of the United Nations (FAO) Panel of Eminent Experts on Ethics in Food and Agriculture has observed that ‘while most innovation for food and agriculture does not depend on IPRs, the acquisition and exercise of IPRs in this field raise a variety of ethical concerns’. 61 These include the fact that ‘IPRs protection may just mean the lack of access to innovations for the poor’ and the concerns raised by the ‘patenting of merely isolated genes, the basic building blocks of life’, which ‘are not invented, but are part of nature’. 62 More practically, the ability of individuals and corporations to obtain proprietary rights over agricultural innovations has important implications for food security, 63 particularly as the expense and general transactional costs have tended to concentrate such IPRs in a few hands. The patenting in relation to genetic material which might be useful in permitting organisms to resist the stresses of climate change mirrors the high market concentration levels which have already been observed in the seed industry and the control of patent thickets by a small number of companies.
The practical effects of the application of IPRs to genetic resources is reflected in the actions which have been brought for infringements of IPRs. To date, these actions have mainly been brought against farmers who have cultivated patented GM crops without the permission of the relevant rights holder, as well as actions against importers of products containing patented GM ingredients. Potential IPR liability also lies against governments, research institutes (international and national) and seed breeders who supply or utilize the proprietary technologies which are indispensable for the development of climate resistant crops.
