PITCH:

The modern regulatory state affects all forms of property rights, from land to chattels to intellectual property. The only constitutional limit on the government dispossessing a property owner, or excessively restricting the use of property through regulations, is the Takings Clause in the Fifth Amendment. But does the Fifth Amendment impose any constitutional limits on the government's infringement or regulation of patents? Join the Federalist Society as a panel of experts discuss the doctrinal, policy, and historical issues raised by this increasingly important constitutional question.
