The biopharmaceutical industry has long been considered immune to the threat of patent trolls, patent holders who seek to monetize the value of a patent through enforcement rather than productive use. But a paper by UC Hastings Robin Feldman and Harvard Fellow Nicholson Price argues that the biopharmaceutical industry should be worried and that steps should be taken now to counter the threat before it blossoms into an industrywide problem. We spoke to Feldman, professor of Law and Director of the Institute for Innovation Law at the UC Hastings College of Law about the study, why the biopharmaceutical industry should be concerned, and what steps can be taken to deter abusive behavior while protecting innovation.
