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.
If the patent term has not expired, you will then want to check with the USPTO to see if the required maintenance fees have been paid. There are three maintenance fees due for utility patents (design patents do not have maintenance fees): 3 years, 7 years and 11 years. U.S. Patent No. 6,854,555). 2  If the competitor's product does not have a patent number directly on it, check the packaging, marketing materials and website for any patent notices. 3  After you have identified a patent number of interest, you can perform a patent number search to view the patent.
