This paper argues that intellectual property rights are incompatible with Rawls’s principles of justice. This conclusion is based upon an analysis of the social stratification that emerges as a result of the patent mechanism which defines a marginalized group and ensure that its members remain alienated from the rights, benefits, and freedoms afforded by the patent product. This stratification is further complicated, so I argue, by the copyright mechanism that restricts and redistributes those rights already distributed by means of the (...) patent mechanism. I argue that the positions of privilege established through both the patent and the copyright mechanisms are positions that do not “allow the most extensive liberty compatible with a like liberty for all.” They do not “benefit the least advantaged.” Nor are they “open to all under conditions of fair equality of opportunity.” In making this argument I critically assess the utilitarian defense of intellectual property rights and find it insufficient to respond to the injustices manifest in our current arrangement for the protection of intellectual property rights.
