Here is a related paper. Seems relevant for IP perspective and discusses patentleft, peer production, and BioBricks Public Agreement.
"What openness might mean in the patent-dominated context of biotechnology remains unclear, however, and has required a reassessment of the analogy to “copyleft” that had provided initial inspiration to the scientists and activists interested in open synthetic biology. I focused especially on the role of the BioBricks Foundation in this effort and explored the rationale behind the decision to pursue a “public domain” agenda via a new legal agreement, the BioBrick™ Public Agreement.
The success of this public domain strategy depends on the viability of peer
production without the advantages of legal coercion available through a “share-alike” licensing provision. In scrutinizing the motivations behind peer production, I borrowed from recent philosophical work critical of the conceptualization of the free rider problem to argue for the rationality of decentralized cooperation, even where individual contributions to a collective project are small. The rationality of such cooperation depends, however, on threshold effects that mark the efficaciousness of individual action in collective endeavors. In the context of
intellectual property, I argued that these thresholds are determined by the presence or absence of shared technical platforms."
