In particular those cases initiated by the patent owner - to proof that a third person's action is infringing his/her patent right - attributed greatly to this increase. Moreover, the rate of trials which turned out successful for the patent owner rose from 17.6% in 2005 to 21.5% in 2009.
According to a spokesperson of the IPT, scope of right trials are treated preferentially at the IPT as these trials are regarded as a particular important tool to solve patent related disputes efficiently.
