      abstract = {We have studied all final patent validity decisions issued  by the federal courts between 1989 and 1996 reported in  United States Patents Quarterly. We test this dataset to  determine a number of facts of interest to scholars and  patent litigators, including the rate at which patents are  held valid, the subject matter of the patents litigated,  the rate at which judges and juries hold patents valid, the  most common grounds for invalidity, how validity decisions  fare on appeal, and numerous other hypotheses.},
