When a company becomes involved in a patent infringement litigation, in-house counsels need to understand the prospects of the litigation, explain them internally, and consider necessary measures. In this case, the “prospects of the litigation” usually include (1) the possibility of winning the case and (2) the trial schedule. It should be noted, however, that in patent infringement litigation, each of the above (1) and (2) is difficult to predict due to the peculiarity of the trial process.
