New White Paper Identifies Patent Thickets as Barrier to US Biosimilars Market and Domestic Manufacturing

“How Patent Thickets Constrain the US Biosimilars Market and Domestic Manufacturing,” authored by Alex Brill and Christy Robinson, explains how reference biologic manufacturers create thickets of overlapping, weaker follow-on patents to keep competitors from entering the market. The paper highlights how originators have strong incentives to protect their profit streams and have found patent thickets to be an easy way to significantly extend the duration of monopolies in the US, preventing access to more affordable medicines for patients.
