Amortization of Intangible Assets. To illustrate the amortization of an intangible asset, imagine XYZ Biotech spends $30 million dollars on a patent with a useful life of 15 years. Theoretically, to account for the expense over a 15-year period, XYZ Biotech records $2 million each year as an amortization expense.
Maintenance and annuities fees increase over time, so the cost of keeping a patent in force becomes greater over the life of the patent. At the time of this publication, the maintenance fee for a US patent during the first payment window (i.e., 3 to 3-1/2 years from the patent grant date) is $1,130 USD. During the second payment window (i.e., 7 to 7-1/2 years from the patent grant date), the maintenance fee is $2,850 USD.
