22. A system for evaluating a patent document, comprising: processor and a non-transitory computer readable storage medium having computer executable instructions stored thereon for execution by the processor, forming: a data input means for receiving data with regard to one or more patent indices, each index characterizing a different aspect of the patent document and contributing to a quality of the patent document, the quality of the patent document being associated with a monetary value of the patent document, each index having a single numerical value and being defined on a bounded interval having respective minimal and maximal values; a processing unit, comprising computer program code stored in the non-transitory computer readable storage medium, for transforming the patent indices into a Patent Quality (PQ) index according to a non-linear transformation, said Patent Quality index characterizing the quality of the patent document by a single numerical value defined on a bounded interval for said Patent Quality index having respective PQ min and PQ max values; said transformation being continuous, monotonous with respect to each said one or more patent indices, and non-linear with respect to at least one of said one or more patent indices; wherein all patent indices are defined on the same bounded interval for each said patent index; wherein said non-linear transformation satisfies the following property: transforming any number of patent indices having equal numerical values holds the numerical value of said Patent Quality index unchanged; wherein said non-linear transformation has a parameter of non-linearity expressed as a real number, and wherein said non-linear transformation is a single-valued transformation providing a single numerical value for said PQ index for any parameter of non-linearity; and an Artificial Intelligence (AI) Unit, comprising an AI system for analyzing numerical values of said patent indices, including generating a conclusion regarding the quality of the patent document based on the numerical values of the patent indices and the performed analysis, and a reason explaining how the conclusion regarding the quality of the patent document relates to the numerical values of said patent indices.
