§1235 Patent Sale — Long-Term Cap Gains Treatment

Individual inventor selling patent gets LTCG treatment regardless of holding period.

Overview

IRC §1235 grants long-term capital gains treatment to individual inventors selling ALL substantial rights in a patent — regardless of holding period, regardless of whether inventor is a 'dealer.' Applies to natural person or their financier (backer). Turns what would be ordinary royalty income into 15–20% LTCG. Post-TCJA §1221(a)(3) excludes self-created patents from cap-asset treatment for POST-2017 creation — but §1235 override still applies to individual inventors.
