1. A computerized method for evaluating a patent document, comprising: in a computer having a processor configured for: (a) introducing one or more patent indices, characterizing different aspects of the patent document, and a Patent Quality (PQ) index, depending on said one or more patent indices; a monetary value of the patent document being a function of said PQ index; (b) the Patent Quality index having a single numerical value, and being varied on a bounded interval for said PQ index having respective PQ min and PQ max values; 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; and (c) transforming said one or more patent indices into said Patent Quality index according to a deterministic non-linear transformation; 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 said patent indices and said non-linear transformation are chosen so as to satisfy the following: tending of any one of said patent indices substantially to a respective minimal value, results in said Patent Quality index tending substantially to one of the following, independent of values of other patent indices: the PQ min ; the PQ max ; and 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.

The method as described in claim 1 , wherein: all patent indices are defined on the same bounded interval for each said patent index; and transforming any number of patent indices having equal numerical values holds the numerical value of the Patent Quality index unchanged.
