Twenty years after Heller and Eisenberg predicted the emergence of an anticommons in biomedical research, this article assesses the currency of the anticommons theory. While a patent-fueled research anticommons does not appear to have emerged in the ways that Heller and Eisenberg envisioned, there are new ways in which the fragmentation of rights -- whether through trade secrecy, narrow licensing or data propertization -- continues to threaten research and commercial development. The anticommons theory thus remains as relevant today as it was when it was first proposed.
