The America Invents Act, the first substantial legislative changes to patent law, took effect two years ago. Late last year, attempts to reform patent law stalled when late opposition to the proposed act was voiced. This year, a number of legislative proposals are under consideration in both houses of Congress. Some proponents of patent reform cite increasing patent litigation as a key indicator that reform is necessary, while opponents argue that the empirical evidence used to support those claims is faulty. Our experts debated new and old empirical evidence, and the underlying need for further patent reform.
