43. A system for evaluating a patent document, comprising: a processor and a non-transitory computer readable storage medium having computer readable instructions stored thereon for execution by the processor, causing the processor to: (a) provide one or more patent indices, characterizing different aspects of the patent document, each patent index having a single numerical value and being defined on a bounded interval for each said patent index having respective minimal and maximal values; (b) transform the patent indices into a Patent Quality index (PQ) according to a deterministic non-linear transformation, said Patent Quality index being varied on a bounded interval for said PQ index having respective PQ min and PQ max values; a monetary value of the patent document being a function of said PQ index; said non-linear transformation being continuous, monotonous with respect to each of said patent indices; said non-linear transformation being non-linear with respect to at least one of said patent indices; wherein all patent indices are defined on the same bounded interval for each said patent index; 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.
