Semantic Patent Informatics: Legal Reasoning with Legal RuleML in the Patent Law IES Fact Screening and Transformation Project (FSTP)


The Artificial Intelligence (AI) and Law communities have converged in the last twenty years on modelling legal norms and guidelines using logic and other formal techniques. Legal RuleML is a new OASIS standard which extends the Rule Markup and Modelling Language standards family (RuleML) with features specific to the semantic formalization of legal norms, guidelines, and legal reasoning. This talk will introduce the use of Legal RuleML for the representation of semantic patent claims as formal ontological statements with semantic annotations from semantic background knowledge and for the representation of patent law systems and their (case) law decisions as legal rules. This semantic model is used in an AI expert system - the IES (Innovation Expert System) FSTP (Fact Screening and Transformation) - for legal reasoning which resolves complex legal questions. Based on a mathematical model called the FSTP Test, which enables determining a non-obviousness indication of an invention to its prior art, by measuring the semantic, in-turn the pragmatic height of the invention through its inventive steps, it automates the analysis of a large number of patent’s technical facts (e.g., patent claims) with respect to their logical coherence in a given patent law system. It can be used to point out logical inconsistencies and can be used to evaluate compliance of patent claims with patent law systems including e.g., claim construction law and non-eligibility
