What Factors are used in computing an IPQ score?
There are over 50 discrete factors that make up IPQ scores. Each factor is independently identified as correlating either positively or negatively with patent maintenance (i.e. whether or not a patent’s maintenance fees were paid). These factors are then analyzed in a regression analysis to determine the coefficients and weighting factors which are ultimately used in calculating the IPQ score. The factors can generally be categorized as Technology Factors (e.g. U.S. Patent Class or IPC), Disclosure Factors (e.g. the length of the detailed description), Claims Factors (e.g. the number or length of independent claims) and Prosecution Factors (e.g. the number of rejections received).
