This article applies van Gennep’s structure of the ritual to the patent application process, arguing that information undergoes several ontological transformations on the way to patentability. The second half of the article applies Turner’s focus on the liminal space. From this perspective, the ‘pure possibility’ of the liminal space is essential to patent law, because it helps negotiate between strong boundaries (as a form of property) and the almost improvisational way in which general rules are applied to specific patents. Taken together, these two approaches provide a more nuanced understanding of how patent law comes into existence and how the patents themselves operate as distinct social and cultural artefacts. The analysis does not intend to replace the economic understanding of patent law, but instead seeks to reflect more completely how it actually functions.
