Most of the studies of the patent system conducted by economists assume that the agency in charge of granting and managing the system functions with perfect efficiency-that is, that there are no transaction costs imposed by the patent system. Thus, in theory, the patent acquisition and enforcement system, as a whole, is a black box that works perfectly. In practice, however, the Patent Office has been subject to harsh criticism over its procedure for granting patents. First, the Patent Office's process for reviewing patent applications may not involve an adequate search for relevant prior art in different technological fields.' Compared with other patent offices, such as those in Japan and the European Union, the USPTO has high rates of acceptance and low levels of review. Second, the USPTO is not free from political influence. Important interest groups that exert pressure on policymakers in Congress and the USPTO directly shape patent policy.

For example, a firm can patent an obvious technology that is not challenged initially because of the small value of the patent. Later, however, this patent could become both valuable and harmful to competing firms. Therefore, having a post-grant system could help provide an inexpensive challenge system for some time after a patent is issued. Nonetheless, for any pre-grant or post-grant system, challengers may still contest a "bad" patent in
