On April 13, 2018, the Company entered into a purchase and sale agreement with Buys, its Chief Technology Officer, pursuant to which the Company agreed to purchase the Buys Portfolio, provisional patent rights, and other intellectual property relating to air and/or gas fired long guns or pistols, including pump action launchers and munitions used with such pistols and long guns, including self-stabilizing shaped or “finned” rounds. As consideration for the Buys Portfolio, the Company paid Buys $100,000, and incurred $10,000 in legal costs to transfer these patent rights. This consideration of $110,000 was capitalized and represents the minimum rights to a license arrangement as patent rights as the Agreement included an option for full acquisition of the rights, conditional upon certain future events taking place. The Company also agreed to pay Buys either $500,000 in cash or $750,000 worth of Company stock within two years at Buys’ discretion, if the Company elected to retain certain patents within the Buys Portfolio, which terms were changed by subsequent amendment. Pursuant to an amendment of the Agreement effective December 18, 2019, the Company made two additional payments to Buys totaling of $776,799, consisting of the Second Payment of $696,799 through the issuance of 3,866,810 shares of common stock and Final Payment of $80,000 in cash. The Final Payment was paid during the quarter ended May 31, 2020. Buys no longer retains any reversion rights or security interests in the Buys Portfolio. These patent rights have a maximum life of 20 years, expiring on various dates beginning from November 2033 to 2038, and are amortized on a straight-line basis over a period of 15 years. The Company amortized $16,219 of patent rights during both three months ended February 28, 2021 and February 29, 2020. The Company did not recognize any impairment losses during the three months ended February 28, 2021 and February 29, 2020, respectively.
