On the Implications, Impact and Countermeasures of Patent Troll.

Patent Troll refers to not only a specific type of patentees in practice, but also the phenomenon of patentees' exercising patents. Patent Troll may be suspected of "indulging in infringement" or "fraud and coercion" causing some enterprises'huge economic losses and intensifying the tool orientation of the patent system, which has affected the healthy operation of the patent litigation system. However, Patent Troll has also explored a model of patent operation; therefore, it couldn'be opposed or supported absolutely. To deal with Patent Troll, the patent legal system should be improved in terms of the judgment standards of patentability and the legal liability of patentees'misconduct. [ABSTRACT FROM AUTHOR]
