1. A computer implemented method for generating a predicted depreciation schedule for a set of one or more patents, the computer implemented method comprising:
- selecting via a computer system a set of one or more patents for which to generate the predicted depreciation schedule;
accessing via the computer system, from a data repository, forward citation frequency data related to the set of one or more patents;
generating via the computer system a lognormal probability distribution function for the set of one or more patents based at least partially on the forward citation frequency data for a selected period of time, the lognormal probability distribution function representing ramp up public awareness of the set of one or more patents, wherein the lognormal probability distribution function is iteratively generated to determine coefficients that produce a best fit estimate of the forward citation frequency data;
generating via the computer system an exponential decay function for the set of one or more patents based at least partially on the forward citation frequency data for a second period of time that is beyond the selected period of time, the exponential decay function representing obsolescence of the set of one or more patents, wherein the exponential decay function is iteratively generated to determine coefficients that produce a best fit estimate of the forward citation frequency data; and
storing via the computer system the predicted depreciation schedule for the set of one or more patents, the predicted depreciation schedule comprising a combination of the lognormal probability distribution function and the exponential decay function, wherein the predicted depreciation schedule is correlated to a depreciation rate for the set of one or more patents.

Abstract
Methods for constructing an estimated depreciated schedule for a patent are disclosed. The steps for constructing this schedule may include: (1) determining a first function which approximately describes the rate of initial increase in expected forward patent citations over time; (2) determining a second function which approximately describes the rate of eventual decay in expected forward patent citations over time; and (3) constructing an estimated depreciation schedule using a calculated decay coefficient derived from said second function.
