Abstract
The invention discloses a system to score assets such as patents based on an event on which information is publicly available and is correlated to a number of intrinsic and extrinsic variables which characterize the assets. More specifically, the invention improves over the prior art by taking due account of yearly life expectancy statistics of patents of the same family in multiple jurisdictions where related patents owned by the same assignee have been filed. For doing so, the system of the invention provides a method to use statistical models of the semi-parametric type such as Cox proportional hazard models or the parametric type, such as Weibull accelerated failure models. These models yield a much improved precise estimation of patents families filed in multiple jurisdictions, the possibility to make available to the users the breakdown of the explanatory power for each relevant variable and validation criteria and the option to choose between different models the one best fitted to their usage scenario.
