Homogeneous geodesics of non-unimodular Lorentzian Lie groups and naturally reductive Lorentzian spaces in dimension three

We determine, for all three-dimensional non-unimodular Lie groups equipped with a Lorentzian metric, the set of homogeneous geodesics through a point. Together with the results of [C] and [CM2], this leads to the full classification of three-dimensional Lorentzian g.o. spaces and naturally reductive spaces

Algae and Biodiesel: Patenting Energized as Green Goes Commercial

In the twenty-first century, predominant dependence on fossil fuels as energy resources will not be sustainable. Developing and commercializing green energy innovations will be an essential component of the transition to a more diversified energy economy. Algal biodiesel is one of the most promising green fuels because of its potential as a renewable and sustainable fuel source without displacing food crops. Algal biodiesel research and development are necessary early steps towards a transition to a green energy economy. The strategic use of strong patent portfolios will drive this by attracting investment, incentivizing innovation and accelerating commercialization. Whereas algal biodiesel research and development is largely still early stage, this will rapidly change as aggressive investments and government subsidies facilitate economically competitive algal biodiesel to enter the energy market. Algal domestication, improvement and industrial utilization for biodiesel production will therefore inevitably create value, leading to increased assertion of property rights, of which intellectual property rights in the form of patents are fundamental. This article provides a summary of representative patents and patent applications in the algal biodiesel technology space and their commercial applications

Golden Rice: A Case Study in Intellectual Property Management and International Capacity Building

In order for agricultural biotechnology (agri-biotech) to play a larger role in the development of sustainable agricultural systems, intellectual property (IP) rights management must be addressed. These issues are not limited to developing countries. With increased globalization, the management of agri-biotech IP rights affects both developing and industrialized countries. In industrialized countries, for example, IP rights risk management entails protection of inventions via strong patent portfolios. For developing countries, IP rights risk management includes the acquisition of rights requisite for the use of inventions essential to the basic welfare of the population. Strategies are needed to bridge these disparate IP management paradigms to facilitate the successful transfer of the agri-biotech from an industrialized country source to a developing country recipient. This paper examines IP management linked to agri-biotech products. Further, this paper examines Golden Rice, a genetically engineered rice strain that accumulates beta-carotene (i.e., pro-vitamin A) in the endosperm tissue of grain, as a case study for IP management, with emphasis on the international movement of agri-biotech from industrialized to developing countries. Topics discussed include: the application of agri-biotech to international development; the challenge of transferring this technology from industrialized to developing countries; a method for evaluating the IP constraints impinging on the deployment of Golden Rice; industrialized/developing country perspectives vis-a-vis IP rights management; six shorter-term options for the management of IP connected to Golden Rice; and a longer-term proposed path to sustainable transfers of agri-biotech products
