This piece recounts the efforts by NGO Sign of Hope (SoH) to rectify human rights violations in South Sudan, which manifested themselves as drinking water pollution by the oil industry. Committed to exposing and remediating this water contamination, SoH was able to prompt the automobile company Daimler’s CSR to engage in extended dialogue with the oil industry stakeholders in Unity State. Despite a tactful use of various methods ranging from cooperation to confrontation, SoH’s campaign did not lead the oil producers to reverse the harm inflicted on the people of Unity State. When SoH tried to hold these companies accountable, SoH had the impression that it was hitting an elastic wall. This piece identifies lessons which may help to counter corporate human rights violations and compensate for the weakness of CSR in fragile states and in the face of corporate irresponsibility.

This article examines a patenting conflict between the Halliburton Oil Well and Cementing Company and an independent inventor named Cranford Walker. It argues that Halliburton’s effort to lower the barriers to entry into the oil well depth measurement industry facilitated the re-emergence of materiality as a pre-condition for the patent eligibility of inventive processes. In 1941, Walker sued Halliburton for infringement of three of his patents, and Halliburton responded with an aggressive defense aimed at invalidating them. Over the next five years, the courts handling this conflict adopted very narrow legal theories developed during the Second Industrial Revolution to assess the patent eligibility of inventions that involved mental steps—processes such as mathematical computations, which people can perform in their minds. The resulting legal precedent cleared the path for Halliburton’s short-term industrial goals and continued to shape patent law for the rest of the century.
