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.
