Is Patents Tax Deductible? 2026 Guide
It Depends
It depends. Patent costs may need to be amortized over the patent's legal life (typically 15 years under Section 197) rather than deducted in full in the year paid. Legal fees for patent applications are generally capitalized.
IRS Form: Schedule C, Line 27
Conditions & Requirements

What the IRS Says
Under IRC Section 197, patents acquired or developed are intangible assets that must be amortized over 15 years. This includes USPTO filing fees, attorney fees, and prosecution costs. However, under Section 174, research and experimental expenditures incurred in developing the invention may be amortized over 5 years (domestic) starting in 2022 due to TCJA changes. Annual USPTO maintenance fees may be deducted as current expenses.
